What does lte mean on iPhone 6s. What is LTE network. Lack of VoLTE support by the operator

Throughout its existence, mankind has tirelessly solved the problem of how to transfer data. This question worried in different contexts. At first, the emphasis was on the transmission of data from generation to generation, which made it possible to promote scientific and technological progress. Later, people became interested in the problem of data transmission over long distances. If a century ago it took years to transmit a message from one end of the earth to another, today the transmission of information takes a matter of seconds. Plus, data transfer plays an important role in conducting experiments, in creating know-how. So, our present and future depends on the ability to share information. And the most important role in such a matter is assigned to wireless communication. Today it is one of the key developing industries.

It is difficult to keep up with modern technology. New ideas and solutions appear constantly. So relatively recently a unique technology of its kind called LTE was born. It should be admitted that this novelty has not yet been appreciated by all modern users. For some, it remains a mystery, while someone actively uses it to achieve their goals and solve corporate or personal problems.

What does LTE mean? Why is everyone so actively discussing this new product? What place does it have in the technology market? If you do not try to delve into the difficult technical features in detail, you can draw a completely understandable picture for yourself.

Three capital letters LTE (Long Term Evolution) have long been found in advertising that is dedicated to communication systems. In translation, this abbreviation means "long-term evolution". Agree, the title is promising.

LTE is a special mobile communication standard. We are talking about a fundamentally new generation of communication, which began to take root in our lives back in 2010. The key feature of LTE is the ability to transfer data at an incredibly high speed (about 100 Mbps for mobile devices and 1 Gbps for stationary devices). Features of LTE:

This standard is not available for simple telephones. Only smartphone users can enjoy new opportunities by connecting to the LTE network.
Communication services are of high quality.
Wireless internet has become even more accessible.
Connection to the LTE network is possible only with a special SIM card.
Users have unlimited access to virtual television, video communication, online games, and multimedia Internet content.

In Russia, there are only a couple of hundred settlements with LTE networks. Not all operators are ready to provide an opportunity to use a new type of communication. But many smartphone manufacturers have already begun to release devices with LTE-modules, as they are well aware that the future of the presented communication is cloudless.

In fact, LTE represents the next step between 3G and 4G. Its main task is to reduce the load on wireless networks. This is a real bold step into the technological future. How LTE differs from 3G:

The new connection is of higher quality.
Its speed is several times higher. You can exchange information ten times faster.
LTE is in great demand because comfort is important to users.

How is LTE different from 4G (4Generation)? Due to the fact that LTE networks do not yet meet the requirements set forth by the International Telecommunication Union, they cannot be considered fourth generation (4G) networks. The list of exclusions includes only LTE-Advanced.

What is lte in modern iphone?

As noted earlier, not every Apple device supports the new communication format - LTE. The iphone 5s works fine on the territory of the Russian Federation. They have been on sale since 2013. Interestingly, the manufacturer of such gadgets decides for himself which networks (more precisely, operators) modern iPhones 5C and iphone 5s will work with.

The fact is that Apple tests the networks of all mobile operators and then allows the use of LTE. Some people think that the locking capabilities are related to the gadget's firmware. But this is not the case. Here you can see the connection between blocking and SIM-card settings of some telecom operators. The reason for this confusion lies in the incorrectly configured CSFB function, which is responsible for the transition from using LTE data to a voice call.

That is, users can skip calls during the time interval when they use next-generation wireless communications. As you know, Beeline and Megafon have permission to use LTE. The manufacturer Apple does not agree to other operators, as it believes that possible numerous complaints from iphone 5s users can damage the company's reputation. It should be noted that the Russian operators named above themselves had to contact the management of Apple Inc.

What is lte? Long Term Evolution translates as long term development and is written with the abbreviation LTE. Operators commonly use the 4G name in their advertisements.

How subscribers of Beeline, Megafon and MTS can connect LTE to Apple iPhone

Wireless data transmission is a rapidly developing technology today. In a world where most of our life is spent on the Internet, high data rates are required. An important component of this phenomenon are communication devices that allow us to access the World Wide Web anywhere and at any time. This trend places high demands on modern devices and the quality of cellular communications.

The implementation of the iPhone 5S in the markets of the CIS countries began at the end of 2013. Many have had difficulty switching to LTE technology in the iPhone. The reason for this is Apple's desire to choose when and with whom of the cellular operators to cooperate. For a long time there was a situation when iPhones were on sale, formally Apple supported lte in the iPhone, in fact it was impossible to connect to it. Today, there has been a long-awaited change in data handling.

What is lte?

Long Term Evolution is translated as long term development and is written with the abbreviation LTE. Operators commonly use the 4G name in their advertisements. LTE does not fully meet the requirements of this type of transmission. Only LTE-Advanced is suitable for this generation.

4G - comes from G (generation is translated as generation), i.e. fourth generation of data transmission over the Internet. In 2008, the quality standards were set: 1 Gbps for stationary devices, 100 Mbps for moving ones. Typically, cellular operators reduce the speed to 20 Mbps to prevent network congestion. Although today this issue has already improved its performance, and at the presentation of the Apple iPhone 6 and 6 plus, the speed of LTE support for smartphones was announced at 150 Mbit / s.

To understand what speed is available for the device, look at the icon next to the link level indicator in the upper corner of the phone. If the location does not have LTE coverage, the previous generation of data transmission (3G) will be displayed. If it is not available, then the earlier generation type will be visible.

There are four generations of data transmission:

GPRS, speed 0.08 Mbps.
EDGE, operates at speeds from 0.06 to 1.0 Mbps.
3G or H +, works in the range of 3-5 Mbps.

The calculation of the cost of the Internet comes from the consumption of 1 MB of data, regardless of the type of connection. When accessing a high speed, the consumption of Internet traffic increases significantly.

What is lte in iPhone?

Apple's decision to open LTE to carriers is because it is testing the carrier in the first place. Only after this procedure is LTE operation allowed. The blocking of the connection goes through the SIM-cards of the operators, and not through the firmware of the apple iPhone, as many believe.

How LTE 4G works on iPhone SE, Nexus 6, and iPhone 6S from the US

Many US smartphone buyers can't figure out if 4G will work on their device. I propose to break ...

Comparison of WiFi and LTE in iPhone 5s, iPhone 6 and iPhone 6 Plus

There is a reason for such blockages. Mobile operators have a poorly functioning CSFB (Circuit Switched FallBack), which is responsible for moving from LTE to making a voice call. Such a situation is clearly displayed by missed calls during lte on on the iPhone.

IPhones starting with 5S and 5C have real LTE capability. At first this was only possible formally. After the direct appeal of Russian mobile operators to Apple, this issue brought about changes. And now subscribers of Beeline, Megafon and MTS, owners of iPhone, can connect LTE. Today, work is underway to improve wireless data transmission and the situation is changing for the better day by day.

How to enable 4g \u200b\u200bon iPhone

When you are a happy owner of an iPhone 5S / 5C and you do not have LTE available, but should, go through the settings to the "main" tab. Click "about this device" and you will be presented with an automatic update of your mobile operator settings. Agree and wait until the end of the process. If, after completing this procedure, the connected LTE on the iPhone does not work, then you need to update the SIM card. Probably the existing one does not support 4G. The supporting SIM card is black with the designation 4G, if you are offered such a white one, be aware that this is a test card and its functionality is still being tested, and there are malfunctions.

How to enable lte on iPhone

Data transfer on iPhones is carried out in several ways. It depends on the mobile operator. It is divided into mobile operators supporting VoLTE and not.

VoLTE support by operator

VoLTE stands for Voice over LTE. On your phone, go to "cellular" through the settings menu and go to "cellular data options". With the support of this technology, the following items will be opened:

Shutdown. Complete disconnection of LTE.
Voice and data. The use of voice calls and mobile data is enabled.
Data only. Voice calls are disabled when mobile data use is enabled.

If you experience frequent connectivity problems or interruptions while using this technology, use a full disconnect. If after this measure the connection quality improves, contact your cellular operator for help.

Lack of VoLTE support by the operator

In this case, the operator uses the GSM standard and offers the following options for handling data:

LTE. Data usage is enabled over LTE or 4G based on available coverage.
3G. Data usage is enabled over the 3G network if the coverage area allows it.

4G designation is possible via UMTS and LTE. It depends on the mobile operator. When using CDMA standard, only "Enable LTE" will be available.

To use the possibility of data transmission, you need to be the owner of a valid tariff plan or have a connection to the World Wide Web. For more information, you can contact your mobile operator.

To receive high-quality data transmission, you need to clarify the cellular coverage area of \u200b\u200bthe operator used, where you are most of the time. Or use the services of the operator with the widest coverage area.

If you find yourself outside the service area of \u200b\u200byour operator, you can use the services of another one available where you are. To do this, you need to go through the settings in the "cellular data" and click on the button "data roaming". In this situation, the service is likely to be paid, so make sure you have funds in your account to pay. After using this feature, to avoid loss of funds from your account, disable "data roaming".

Almost all modern smartphones have LTE support, but not everyone knows what it is and whether it can be classified as an advantage. It turns out about the following picture - having acquired a new-fangled phone with this support, people do not know how to apply it in practice. Trying to figure it out on their own, as a rule, they come across a technical designation that includes a lot of related terms, and their intricacy, instead of explanation, confuses even more.

Trying to briefly explain what LTE is essentially, it turns out that it is a modern Internet standard for mobile devices. It is even simpler - an intermediate link, familiar to all 3G and 4G users, but at the same time, it has no direct relation to any of them, only indirectly. To fully understand, it is necessary to understand what these differences are.

The decoding of the abbreviation is Long-Term Evolution, which fully reflects the purpose, but does not explain its features, and what they are. When connected, the 4G LTE icon appears on the smartphone screen - this is a kind of hint, no more, since the connection between the two standards is rather blurred. Even to compare 2G, 3G, 4G with the modern development standard is wrong, it is developed on the GSM / EDGE and UMTS / HSPA platforms. This provides an increase in bandwidth and speed qualities when connected to the network, while improving its core, achieved thanks to a radio interface different from the same 4G. The patent belongs to the 3GPP consortium, a recognized creator of specifications designed to improve the overall performance and capabilities of mobile telephony, and is identified in its documentation as Release 8.

LTE essentially refers to updated wireless standard, used by GSM / HSPA and CDMA2000 network operators, this is the main difference from 2G and 3G. It is simply not compatible with them, because it uses more advanced digital processing techniques for signal transmission and modulation. In addition, it operates on different, separate frequencies from them, using different band options, which may differ within the country or region of its use. The difference between the standards becomes clearer when you look at a comparison that shows their main characteristics:

Overview of technology features

The main goals that were pursued when creating LTE are multiple increased throughput and speed have been fully achieved. This is facilitated by a radically new method applicable for digital processing and modulation, developed at the end of the last century, but introduced in practice only 15 years later. Another set goal - a complete reconstruction of networks aimed at simplifying their architecture and transferring them to the IP basis, in order to reduce transmission delays, has not been fully implemented. Most likely, the final update will be presented in Release 9, which is under development and is not yet being prepared for release as a full-fledged 3GPP product. The capabilities of the 8th release provide the speed of reception and transmission, within the limits of 326.4 and 172.8 Mb / s, respectively, with support for bandwidths from a minimum of 1.4 to a maximum of 20 MHz. Connection and transmission delay, at the same time, it is reduced to the indicator - 5 milliseconds.

In theory, radius of action LTE is not limited, but in practice this is not confirmed, it entirely depends on related factors: the distance of the signal source, i.e., the base station, the power of the radiation and radio frequencies. The maximum data transfer rate is possible at a short distance, and a radius of 20 km is the absolute limit of the possibility. An example is a comparison involving the distance and frequency range required to achieve a speed of 1 Mb / s:

Station operation in the range 2600 MHz (applicable by most Russian operators), capable of providing coverage and specified speed, up to a maximum distance of 19.7 km.
Radio frequency operation 1800 MHz (used by the most often world operators), although it has the necessary capacity, it can provide high speed within a radius of 6.8 km.
Base stations with range 800 MHz (far from the most popular among all operators), provide high traffic speed over a fairly long distance, the maximum range of 13.4 km.

Despite the fact that the developers of the standard have not fully realized its potential, the modernization of 3G UMTS and work on simplifying the system architecture have a positive result. Mostly, this is reflected in its transition from a complex UMTS circuit structure using a circuit-switched network connection to a unified and simplified all-IP infrastructure. And the use of the E-ULTRA wireless interface, which became the main one, allowed LTE to receive the following features and benefits:

FDD and TDD technologies

FDD and TDD contain the main characteristics of the network, indicating the applicable methods for dividing channels - into receiving and transmitting, between the mobile device and the signal source. Both technologies, independently of each other, share counter streams data transmission, preventing their mixing and intersection of communication channels. It is not difficult to understand what they are for using a simple example: LTE without FDD and TDD is a high-speed highway with oncoming traffic. Without these technologies, it is not able to fully function. It is not very convenient to describe their use in conjunction, each has its own purpose, therefore, they should be considered separately.

FDD technology

Frequency Division Duplexing (frequency division duplexing) - a radio channel, when dividing data streams, using completely different, unrelated and non-intersecting frequencies. Thanks to this feature, reception and transmission can occur simultaneously, and the counter streams do not interfere with each other in any way, there is no interference and this does not affect the FDD throughput. At the moment when both channels are in the active phase, the networks maintain the minimum signal delay and high speed. Frequency division technology, having a number of advantages, is used mostly by Russian and foreign operators.

TDD technology

Time Division Duplexing is a radio channel that uses a single frequency to separate data streams into incoming and outgoing streams. To avoid mixing them, there are 2 different modes that are used alternately at different times. At a certain moment, depending on the active mode, only one of the functions is available for the smartphone or tablet, and for the base station. Using one channel for both receiving and transmitting limits bandwidth TDD, in this regard, technology is much inferior to FDD in functionality.

There is a possibility of setting asymmetric sections at the discretion of the operator, due to the prevalence of the transmitted volumes over the received ones, such measures are aimed at increasing the throughput. But there is also a negative side to this - asymmetric segments cause delays in symmetrical communication. The use of TDD in conditions of limited frequency range operation is relevant, to provide communication for a large number of users concentrated in a small area.

LTE position in Russia

The history of using the LTE network among Russian subscribers began in Novosibirsk, at the end of 2011, when Yota officially launched over 60 base stations. Before this happened, work was carried out in a test mode, the services were available to local residents completely free of charge with the presence of an appropriate USB modem. The next operator that provided subscribers with a connection to the new technology was Megaphone, which launched it in the spring of 2012. It is interesting that the residents of Novosibirsk were again the first to connect, and for Muscovites it became available only after 3 weeks. At the moment, the coverage area of \u200b\u200bthe LTE network covers the territory where about 70% of the country's population lives, but only 2/3 use it. In general, the situation is non-standard, considering that the coverage level is radically different, depending on the specific operator, and in most cases the connection remains available only within the administrative centers of individual regions.

As of the end of 2016, there were 111500 base stations throughout the Russian Federation, while a year earlier there were 72,200, their number increased by almost 55% in 12 months. Almost half of LTE stations are concentrated in the Central Region - 41,000, the smallest number in the Far East region, where there are exactly 10 times less of them. Currently, there is a full-scale modernization, especially in terms of the transition from CSFD to VoLTE, however, the launch of the new approach is still in test mode. The situation is complicated by the use of each of the operators different frequencies and types radio channels. However, there is a hope that after the conclusion of an agreement between MTS and Beeline on joint activities in the development of technology, others will follow their example. Such cooperation is necessary, the transition to LTE technology is happening everywhere in the world, for example, in South Korea it is already used by 97% of subscribers, in neighboring Kazakhstan 81%, in this it takes 7th place, Russia with 49%, only 54th in the ranking.

LTE support by mobile devices

Modern gadgets, both smartphones and tablets, in the overwhelming majority, are designed for a high-speed Internet connection - this is a mandatory standard. For them, video communication, viewing high-definition video and other projects related to the exchange of data are equally important, this is the degree of their functionality, reflected in the cost of mobile devices.

The former gimmick not so long ago, 3G, is gradually becoming a thing of the past, against the background of the lightning-fast development of technologies, it no longer meets many requirements and it happens unable to provide the required connection speed. The ability to support LTE technology is inherent in smartphones, tablets and other gadgets themselves, this is the main and only condition for connecting to the new standard. What it is should be considered in more detail to understand whether the device meets the established requirements.

Characteristics of mobile devices

The necessary characteristics of gadgets for connection are mainly in their high-speed features that support the new format. They are expressed in the following indicators of a single device:

Connection benefits

It is quite obvious that the high speed of the Internet connection on mobile devices is of great importance for all users without exception. Hardly anyone likes endless downloads or transfers of small files, no matter how they are expressed. And the high speed provided by LTE technology means almost unlimited possibilities in the network:

Disadvantages of the new technology

There were some drawbacks here, but they are few in number, and most of them are either far-fetched and belong to the category of hoaxes, or they have been exhausted through modernization and improvement of technology. Therefore, it makes no sense to even voice them, since they are not relevant at the moment.

LTE to iPhone

There is a historical connection between them - the first smartphone to support the latest standard at that time was the iPhone 5, although there were variants that did not include support for it. But all subsequent Apple products invariably contain it. In addition, the "apple" family is equipped with high-frequency LTE-modems based on Intel or in other configurations from Qualcomm. The only inconvenience in the fact that on the territory of the Russian Federation, they operate exclusively in the 1800 MHz range, but the list of frequencies is currently expanding.

4G and LTE - what's the difference

With all the advantages of the new format, the superiority of 4G should be recognized in some areas. They belong to the same generation, they are often compared and contrasted, but they are not confused with each other, because they are far from the same thing. What is the advantage of 4G over LTE:

Maybe in some way LTE is inferior to 4G in a smartphone, but it cannot be classified as less developed. It will be enough just to look at the statistics to make sure that the whole world is gradually moving to this standard. What this is connected with is described above, and the main message is contained in its very name - long-term development. And that's it.

Due to the rapid development of mobile communication technologies, many are wondering what is LTE in the iPhone? To answer this question, you need to understand what LTE is. Why is it needed at all, and what advantages does it have.

LTE is a wireless technology that belongs to the 4G standard. The main difference of the technology lies in the increased data transmission speed, as well as the improved communication quality. LTE theoretical speed is 300 Mbps for data download and 170 Mbps for uploading. However, due to the fact that the technology is still under development, and is also only being introduced on the network, the actual speed is 100 Mbps when downloading and 50 Mbps when uploading information.

So far, my speed is enough for less money. Thanks for the input and against! I currently have an old limited volume subscription and do not want to switch to new ones for cost reasons. It has always been the case for me that I had to buy a discounted, new subscription. If you absolutely want to stay with your current subscription, you need to buy the phone at full price.

So we are doing another one on Paranoia. Meanwhile, thanks to Edward Snowden, we all know that Americans are almost everywhere because they force companies to provide their exclusive access to their databases. I don't need to enter code. No, you don't need to change your subscription, but you have a different price. You can choose from various options. Pada's statement does not apply.

In addition, LTE technology has a peculiarity that it uses the existing infrastructure for its implementation, which makes it possible to reduce the costs of networking. In addition, only LTE allows the transition from 3G to 4G networks smoothly and imperceptibly for subscribers. As a rule, all devices that are equipped with the LTE module are capable of operating in third and second generation networks. Thus, even if the subscriber leaves the LTE coverage area, the device automatically switches to 3G / 2G networks without losing communication.

What can she do with your fingerprint if you are not breaking any law and living like an ordinary citizen? Let's see how long it takes! Fortunately, each consumer can decide for himself. The fingerprint sensor in a smartphone is stimulating everyone, but it doesn't matter for years, laptops with such scanners are probably not interested. These laptops are especially popular with companies with a fingerprint sensor.

Frequency chaos: 44 groups worldwide

Since they are well defined, interested parties can find in the table at the very end of the article. The large number is due to the fact that different frequency bands are available in different countries. In a short but comprehensive overview, we were able to analyze the most relevant points of both devices. It is lightweight, stylized and will be available in gold, silver and black, giving it an air of elegance. In the latter case, it combines an editor like the one we already know with a thin time range that can be personalized depending on when we want to implement this option.

1. So what is LTE in an iPhone

LTE technology opens up a lot of new opportunities for subscribers. In turn, operators are able to provide users with a wider range of services. The LTE module in the iPhone allows you to take full advantage of the technology. These include:

High data transfer rate;
High quality communication;
Lots of new features;
Full HD video viewing in real time;
Creation of video conferences with business partners;
Reducing the cost of communication;
Creation of a single global global LTE network.

Thanks to these advantages, you can contact a person who is on another continent at any time to resolve various issues.

There are some people who don't like the huge bezel around the screen - of course it's a phone with thick wallpaper, but that doesn't bother me. Plus, the size fits perfectly in the hand and doesn't require extremely long fingers to cover the screen. The phone comes in black, silver, gold and pink colors. All apps load at the same speed and perform the same actions, at least in front of my human eye.

It's great to have more screen space, especially for those who often use their phone to read, play or watch videos.

However, today, different countries use different frequency bands in which LTE networks are built. Because of this, smartphones that work in the United States cannot work in Russia. For example, modern iPhone models with LTE are equipped with LTE models capable of operating at 2100 MHz, while in Russia for LTE networks, frequency ranges are used in the range of 791-862 MHz and 2500-2700 MHz.

Good strength, good bonding

It's very good that the manufacturer's input phone has this feature.

This is due to the different frequency configurations of the same product, which is divided into models. You should definitely request to unlock or unlock it. Otherwise, you won't be able to use it here. Get the chip from the local operator that operates there: International roaming.

In this regard, the question arises: is it worth expecting that the new iPhone LTE models will support Russian networks?

According to Apple's management, the new iPhone 5 model will be universal and will be able to work in almost any country in the world, however, not for all operators. The company began production of three models of the new iPhone:

GSM model A1428:
GSM model A1429:
CDMA model A1429.

2. LTE for MTS: Video

This way you make sure the device is unlocked. With that in mind, let's move on to products that can be compatible with this frequency. Operators: Tim, Claro, Vivo and Oi. Operators: Tim, Claro Vivo and Oi. Brazil, Dominican Republic, Austria, Bahrain, Belgium, Chile, Croatia, Denmark, France, Germany, Iceland, Italy, Latvia, Liechtenstein, Luxembourg, Malta, Moldova, Montenegro, Norway, Poland, Portugal, United Kingdom, Romania, Russia, Sweden and Switzerland.

Australia, Korea, China, Hong Kong, India, Malaysia, New Zealand, Singapore, Sri Lanka and Thailand. Latin America: Colombia and Venezuela; Do not buy. It's never too late to remember that Leo has sharper teeth and claws than ever, especially for electronics.

With the CDMA model, everything is clear, but Apple is creating a GSM model for the first time, and the reason for this is the significant fragmented LTE technology. Because of this, the company had to develop two variants of the GSM iPhone. One model for the US and Canadian market and one for the rest of the world.

The result is as many as three iPhone options for the whole world. However, none of them support the frequencies of Russian operators. The GSM model A1429 is designed for a frequency of 2100 MHz, in which most operators in Europe operate. But as already mentioned above, in Russia for the construction of LTE networks, other frequency ranges are allocated, which differ from those supported by the Apple mobile device.

Almost all devices are now compatible with frequencies leased by Italian mobile operators. But customers of other mobile operators will also benefit. We create standards and throw them into the clay. In stores you cannot find models from other countries, at least not with the previous models they made. It is not so impossible, and indeed very likely. The vice of all transnational corporations. Well, the Australian judge gave an explanation to the appellants. If anything, it would be too pretentious to give you anything other than what you bought. The latter even took the camera hostage, demanding even a refund of shipping costs for return, despite the camera having an obvious manufacturing defect. Repair yes, but not replacement. ... Made with great care.

But recently this problem has been resolved. A smartphone from Apple has entered the Russian market, which is capable of working in Russia, or rather in Russian LTE networks. The new iPhone 5C and iPhone 5S provide users with high-speed Internet access in Russia, opening up new opportunities for LTE mobile subscribers. These models are, of course, not cheap, and not available to everyone. But given the rapid development of technology, we can safely say that in the near future such devices will become more affordable.

Carved with extreme precision. It is not just the product of what is technologically possible, but technologically useful. It is not only a vision for the future, but also an inspiration for the future. Here is the technology today. Chip with 64-bit architecture. Fingerprint identification sensor. Improved and faster camera. An operating system designed specifically for the 64-bit version. Each of these features will give any smartphone a significant edge. The good news is that they are all in one smartphone.

Also available in silver and gray. And it is felt in every way. Beautiful aluminum body. The elegance of metal and glass. Sapphire crystal main button. This level of design and sophistication is unmatched today. In three elegant colors: gold, silver and sidereal gray. Entering the code at each deceleration. It is a convenient and secure way to access your phone. The world's first 64-bit smartphone. In other words, a desktop-worthy architecture in an ultra-thin phone.

In addition, the Russian mobile device market has a lot of smartphones from other manufacturers that allow you to enjoy all the advantages of LTE technology.

Apple has decided not to release one model of the iPhone 5s and iPhone 5c with support for all LTE versions, as some other manufacturers do. The reasons are quite clear - fewer chips make the phone's prime cost lower and its power consumption lower. Instead, the company produces several varieties of the same model. And although it follows from the specifications that some versions should work in Russian LTE networks, in practice, as experts have found out, this is not the case.

The difference is staggering. Take on imaginary game worlds. Textures and shadows are more realistic than nature. The sun reflects on the water. Everything is much more realistic. Auto focus is twice as fast, image capture is faster and video frame rate is higher.

Perhaps this will affect autonomy. A new level of productivity. Therefore, they consume less energy. The plans therefore automatically switch from driver navigation to pedestrian navigation when, for example, you park and continue walking.

The world's most popular camera still gives you a smile. New camera app. You can now capture square images. Or select one of eight real-time filters and apply it before or after shooting. Use the Snapshot filter to get a vintage patina for a group photo on the beach.

For those who missed everything or managed to forget it: in Russia, the 2600 MHz frequency range is relevant for LTE networks. To be precise, we are talking about LTE band 7 - this is LTE-FDD, the more popular version of the standard in the world - and band 38 - and this is a slightly exotic Chinese version, TDD-LTE. In band 7, the networks "Iota" / "MegaFon" and "Beeline" were initially built. MTS tried to follow a special Chinese path - but in the end it still switched to the development of the same band 7. As a result, that MTS 4G network works in this range, which we have been lucky to use for the second week.

Or choose a black filter to capture a breathtaking black and white self-portrait. Video stabilization limits the jolts of adrenaline-filled sequences. With up to 10 faces detected, no one will be lost in the crowd. Take even-numbered photos during video recording when you want to document your story.

Its large pixels and an improved rear light sensor increase its sensitivity in low light conditions - perfect for sharing a Mediterranean sunset with a Parisian friend. A completely new perspective. To improve it, it was necessary to simplify it more, make it more enjoyable and practical without breaking user habits.

At the same time, the previous generations of Apple mobile devices - both "retina" iPads and iPhone 5 - did not support either band 7 or band 38. There are many reasons for this, but in general they can be reduced to a rather short sentence: it was not possible to provide good "omnivorousness" existing hardware, and in the priority US market for Apple, fourth-generation networks operate in very, very different ranges. Since Russia in the top list of Apple occupies a place near Nigeria and Pakistan, we could only wait and hope.

All your favorite apps have been updated to make it even easier to find and use. Several versions for this model. Classic model sold everywhere except China. The model representing most of the problems with three device versions. Simple and easy installation, no software installation required.

Manual switch to switch cards. While we wait for the official platform updates, we also understand which devices will be able to receive the update. The new smartphone is well positioned to become a hit in the market and become more popular than its predecessor.

In principle, at the time of the release of the iPhone 5, this worried only the most seasoned mobile analysts. At that time in Russia, at the very least, there was only one LTE network - "Iota" / "MegaFon" - and even that, to put it briefly again, was not ready for full-fledged work.

Over the past year, everything has changed a little. To begin with, recently 3G networks in the Moscow region have begun to work in much the same way as local roads. Thanks to dear operators who have blocked their networks with ultra-cheap subscribers, who enjoy using unlimited Internet for $ 5-7 a month (if you have American friends, tell them about local tariffs for mobile Internet and see what size their eyeballs will reach during the story ).

Consumers have the ability to customize how the battery works based on their habits and get maximum performance. The body of the smartphone is of a one-piece type and the back remains static without removing it. Running with a claw, we cannot find the edge here.

Looking at the body of the smartphone, we will also notice that the speaker grill is no longer at the back, but at the top right side. According to initial data, the tech giant has agreed to invest in at least 10 different television programs. If you can't wait to try out its features on the new platform, you know that it won't support 32-bit apps. This is bad news for users and developers. Other categories most affected are entertainment, lifestyle and education.

At the same time, only the “select few” have gotten to the LTE network so far: firstly, for access it was necessary to buy relatively expensive equipment, and secondly, the same “MegaFon” did not let everyone into 4G, but only subscribers of rather expensive tariff plans. ... For advanced Muscovites, the LTE network has become something of a helicopter, if we continue the analogy with the Moscow transport realities: more expensive, but fast and without traffic jams.

Once you do this, all 32-bit programs will appear in alphabetical order. This is the release of the much anticipated of all. You are probably more interested in how fast the new network will be. Video calls. Higher speeds will also have a huge impact when playing online, as it ensures your game is smooth and consistent. Streaming video.

Upload photos. One of the things many cloud services offer is fast uploading of photos to the servers of the company that offers them. Thrones are not only suitable for entertainment, but they can also revolutionize commerce. In this case, however, the drones must be permanently connected to the Internet and thus be controlled remotely. Thus, vehicles can be tracked on a map and even broadcast live video of their flight.

Red highlighted versions of iPhone 5c with support for Russian LTE networks

Red highlighted versions of iPhone 5s with support for Russian LTE networks

Reason for Celebration - iPhone 5s (left) and iPhone 5c model listings, including two versions each with support for our frequencies

Therefore, at the time of the announcement of the iPhone 5s and 5c, not only confused specialists were happy about the support of the LTE bands that are relevant to us. However, this joy turned out to be premature: the "gray" iPhones brought in in the first days of sales did not work in our networks.

And this is how it looks on the MTS network: there is not even a hint of LTE

The fact is that smartphone manufacturers practice software disconnection of LTE for those networks in which there may be problems with communication. They can be understood: even though the operator is to blame, the user will also swear at the manufacturer of the phone. And who should be so substituted? Yes, nobody. For example, Nokia did this in due time - it turned off the LTE support for Russia in its devices, and after a while turned it on.

In our review of the iPhone 5s, we wrote that something similar would happen to Apple. And it was predicted that LTE support could be included in new iPhones by the time official sales in Russia begin. However, this was probably an overly optimistic forecast. There is a suspicion that it will take a little longer to wait. Or not even a little.

In "MegaFon", it seems, they themselves do not really understand what is happening

There are several reasons for this. First, as mentioned above, Russia is a secondary market for Californians. Secondly, Yabloko has a reason to dislike Russian operators. Thirdly - and this is the most important thing - the LTE networks of our dearest "opsos" are still in a far from ideal state. So it's not at all a fact that Apple will approve of them: the company is very sensitive to checking networks for compatibility - it obliges the company adhered to the principle "we do not do unnecessary functions, but everything that we have in mind should work perfectly."

I must say that the "Russian question" is not the first time that Apple has deprived subscribers of a particular operator of access to the 4G network. In principle, by the time the iPhone 5 was released, there were not many networks in the world in which LTE was implemented in such a way as to suit Apple. So many had to endure.

This first happened with the Swiss operator Swicsscom, which launched its LTE network in November last year - after the launch, subscribers using the iPhone 5 were surprised to find that 4G in their smartphones was not working. They had to wait two months for the happy ending of this story. Another example: subscribers of the American T-Mobile waited for "approvals" for about a month after the launch of this operator's LTE network.

At about the same time, the customers of the Norwegian operator Telenor were expecting the opening of LTE access in the "five". Basically, he developed the network in the very band 7, with which the fifth iPhone could not work, but in one of the largest cities in Norway, the network worked on the supported band 3 - despite the technical possibility of working, initially access was not open. O2 UK subscribers are suffering with us right now from the lack of 4G in the iPhone 5s and 5c. The network should be approved by Apple "within a few weeks." Similar stories happened with the Malaysian Maxis, not to mention the Tajik Babilon Mobile - the latter's network did not manage to get into the "white list", despite the fact that it initially works on band 1 and band 3 supported by all iPhones and iPads.

However, in our case, there is one nuance that greatly complicates everything. The fact is that none of the existing fourth-generation mobile communication networks in Russia at the moment, by and large, is ready for normal operation. Consequently, it may turn out that it is not ready for Apple certification either. For example, Beeline deployed 4G only within the Garden Ring - it's not even a joke to call it a network.

Beeline's LTE network coverage on the map looks like a spit into the soul of Russia

MegaFon has problems of a different kind: the network of this operator is more extensive, but its work is rather intricate. Despite the fact that the company has already acquired the Yota network, which it previously used for outsourcing, the normal integration of these networks has not yet taken place - and, given that the economy is not simple, it is not clear when the MegaFon and Yots "will finally merge in ecstasy.

The largest LTE network in Russia - MegaFon

In addition, MegaFon still does not support CSFB technology in all regions - at the moment this is the only option for our operators to provide voice transmission in the LTE network. The fact is that in the LTE standard, as such, voice communication is not provided - it is assumed that voice transmission will be implemented through packet data transmission (VoLTE - Voice over LTE), that is, speaking quite roughly, like a certain operator Skype. However, the implementation of this option is still hampered by our legislation.

Therefore, Russian operators have to use "crutches" - the same CSFB (Circuit Switch FallBack). The essence of the technology is that at the time of the call, the smartphone switches from the 4G network to the 2G / 3G network - accordingly, if CSFB is not supported, and access to LTE is open, then you will simply skip incoming calls, and to make an outgoing call you will have to manually switch. In short, in the absence of CSFB support, a smartphone turns into a tablet - and this arrangement is unlikely to suit Apple.

The best at the moment are the chances of the third representative of the Große Troika. Like Beeline, MTS has implemented and operates normally with CSFB technology. But, unlike the yellow-blacks, the red-whites have a much wider network. It is still considerably inferior in terms of coverage to the megaphone, but at least to see the coveted LTE icon on the smartphone screen, you do not have to walk under the walls of the Kremlin: you can try your luck in more remote areas of the capital - and even the Moscow region.

What's the bottom line?

Let's summarize. It is not yet clear when Russian iPhone 5s and 5c users will have access to fourth-generation networks. You will have to wait at least until the launch of official sales in Russia. And the maximum is difficult to identify - it all depends on how Apple's perfectionism will manifest itself in assessing the real performance of our networks. As mentioned above, there are many reasons for refusing to approve.

iPhone 5s of the correct version A1457 so far works in Russian LTE networks with no greater success than the iPhone 5

MegaFon subscribers will probably wait until the operator implements CSFB support in all its regional subnets. Perhaps even up to a more interesting moment - before the full integration of their own network with the Iota network, their joint work is now very intricate. So far, it seems, nothing shines for Beeline clients - that small speck of LTE coverage, which this operator has now, cannot be called a network. MTS has no problems with technology, more or less good coverage - we can assume that this operator will still be able to meet the deadline and get Apple's approval for the start of official sales of new iPhones in Russia.

You can't blame Apple for the delays; the company just wants to make sure everything works as it should. Who's guilty? Of course, our operators - some of them delayed the development of the network for too long. They waited for the rooster to peck - and then he pecked. The latter deployed it in an overly cunning way. Both of them will have to try hard to bring the nets into a divine form. There is no better incentive for this.

Yes, you can also send rays of love to those who are largely responsible for our 4G networks in such a depressing state - the gentlemen who are directly involved in the distribution of frequencies. But this is a separate topic.

LTEhe is 4G LTE, is a promising technique for high-speed information transfer via GSM / EDGE and UMTS / HSPA protocols in telephones. It is known that LTE is a standard that is primarily intended to increase the speed of data exchange using mobile phones, PDAs and other interactive devices with the ability to connect to cellular terminals of mobile communications.

What it isLTE 4 G on smartphones? As the “fourth generation data transmission standard” for telephones, LTE is a logical evolution of the older data transmission standard, the third generation standard also known as 3G.

The LTE standard is based on the concept of maintaining the maximum reduction in the cost of transmission, with a concomitant increase in speed and the possibility of a promising optional connection of various information services.

In other words, the creators of 4G LTE set themselves the goal of developing a more sophisticated and at the same time cheaper method of transferring data to phones, which, in addition, would become the basis for further improvements and innovations. And I will note that 4G LTE fully satisfied their ambitions. You can truly understand that this is LTE only by using this technology for a while on your gadgets.

LTE technology characteristics

Thanks to the innovative digital modulation technique of the radio signal and optimization (existing at the time of 4G LTE development) architecture of 3G networks, the new stream was able to provide data transfer rates up to 326.4 Mbps! And this despite the fact that the delay between sending packets was reduced from those that existed at that time 2.8 seconds to 5 milliseconds!

In addition, this 4G LTE technology allows radio traffic in the widest frequency range from 1.4 MHz to 20 MHz, and even supports frequency channel differentiation (FDD), which makes it possible to use this protocol for a variety of auxiliary options, for example, for IP telephony, voice exchange based on VoLTE technology and other "weighty" packet transmissions.

It should also be noted that this LTE technology, due to the optimization of the architectural developments of the 3G network, makes it possible to connect up to two hundred active subscribers even to a standard 5 MHz mobile cell. Thanks to this feature, the 4G LTE standard made it possible not only to increase the existing characteristics of 3G networks, but also to reduce the direct cost of data exchange, since fewer pieces of equipment were now required to provide radio exchange of the same number of devices.

The difference between 4G and 3G

In addition to the above-described key features, which are a logical development of the developments of the 3G standard, 4G LTE also boasts unique features, in particular:

Possibility of interaction with the E-ULTRA protocol;
A conceptually new technique for supporting signal transmission mobility, allowing radio communication with a terminal moving at speeds up to 350 km / h;
Radio switched packet data;
Previously inaccessible ranges of the frequency spectrum.

How can I connect to the LTE network

It should be noted that the majority of modern devices supported LTE even before its widespread introduction, and this is no coincidence - the developers focused on the possibility of cooperation with old GSM / EDGE, UMTS and CDMA2000 client terminals (mobile phones, PDAs). We figured out what this LTE standard is, now we will learn how to use LTE on the phone.

However, to use all the advantages of this protocol "to the full", you will still need a device that supports the 4G standard, since otherwise the data transfer rate will be limited by the parameters of the client device, and not by the power of the cell tower.

As for the software configuration, no applications or utilities are required for pairing with the 4G LTE network - it is enough to register the terminal with the standard authorization data of the cellular operator. Simply put, if your phone went online on the territory of the Russian Federation using the 3G protocol, then "finding" a 4G LTE cell, it will connect to it without any participation on your part, and you will only have to be content with high-speed mobile Internet.
