Frequency distribution in the range of 800 MHz. Cellular frequencies in Russia. Modern clock frequencies: there is practically no “nominal”

Quick answer: 800 megahertz in modern processors is normal. Moreover, this is a very cool feature, not a device failure. Electricity consumption in this "reduced" mode is minimal. And as soon as all the blatant power of 2-4 gigahertz is needed, the processor will give them out instantly, or even add another 300-500 MHz to the nominal frequency. By the way, he will add it himself.

But why is the processor frequency sometimes reduced to "indecent" 800 megahertz?

What is a CPU, is it a processor?

One of the key devices of any computer (and near-computer monster such as a smartphone, TV, and even WiFi router) is the CPU. This is a chip with an area of Matchbox, and in thickness - a couple of matches. Laptops have even less CPU. In phones, the processor area is generally comparable to a penny coin. CPU, by the way, is the standard abbreviation for a processor, "Central Processor Unit". Russian analogue - CPU, "central processing unit".

The task of the processor: calculations. Everything that happens on the PC screen, and everything that is hidden somewhere in the depths of the “iron box” are numerical transformations, and nothing more. Even a letter on a monitor is not just a letter; is the symbol represented by:

1. Numeric code
2. Color and font with a specific digital designation
3. Points on the screen that have their own numerical coordinates

The above is only an incomplete example of calculations for only one letter, with which the CPU works.

What is the frequency of the processor and how to understand this characteristic?

Clock speed (in simple terms) is the number of simple digital operations that a processor can perform per second. 2.5 gigahertz = 2.5 billion addition, subtraction or multiplication of prime numbers. Frequency is one of the many characteristics of the CPU, but far from the only one. The higher the frequency, the more powerful the processor, in principle. But - it is "in principle".

The truck engine is many times more powerful and larger than the 3-4-cylinder passenger car engine. But faster and more dynamic a car. Same with CPU speed.

Let's look at an example. The more powerful the engine of the car - the faster this car? This is far from true. For example, the Kamaz engine is many times more powerful than the engine of a passenger car. Which of the two cars is faster? That's right, the small car will easily leave behind a multi-ton colossus despite all the hundreds of KAMAZ "horses". So it is with the frequency - the more powerful, the faster the computer. But only under otherwise equal conditions.

Typical processor frequencies have not "growth" for 10-15 years. As the Pentium 4 appeared at one time with their 3-3.4 GHz, these frequencies remained a kind of standard for productive systems. Further growth of this characteristic only leads to an exorbitant increase in heat release and energy consumption - this is the law. And who needs a computer that eats electricity like a vacuum cleaner? And with the heat dissipation of a small iron? A laptop that can work without an outlet for no more than half an hour is also a strange device.

Therefore, the creators of processors (primarily from Intel and AMD) are working on strengthening other characteristics of the CPU. The number of the smallest "organs" of the processor - transistors - increases, while their size decreases; delays between individual CPU blocks are categorically reduced - this is progress in computer performance. The banal increase in clock frequency has long exhausted itself. Why is that? Plants need water and sun - but they are good only up to certain limits. If you pour water on a flower, it will die. If you plant a rose in the desert, it will burn. So the processor frequency is good only up to a reasonable limit, and then harmful.

My computer is running at 800 megahertz - what should I do?

Rejoice in progress computer technology and for having a decent modern PC. After all, the processors of our time (from about 2007-2008) are such powerful devices that most often there is simply nothing to load them with. Excess power is needed only at times of high computer load. Just as a truck doesn't need hundreds of horsepower when it's only carrying a driver without a load, the extra gigahertz wastes electricity (and godlessly drains laptop battery).

800 megahertz of the processor (in the screenshot it’s 798.1 at all) is state of the art technology lower energy consumption.

Processor designers decided to “dump” extra frequencies when the computer does not need them. Have you moved away from the keyboard and mouse? In a minute, the operating system will “understand” what can be disabled excess resources, and after another 50-100 nanoseconds (precisely nano!) will lower the frequency of the processor. It took power (for example, when opening a browser, page, or even the usual Notepad) - and after the same 50-100 ns, the frequency jumped from an obscenely weak 800 MHz to the classic 2-3 GHz. Almost instantly.

Electricity is saved, fans run quieter, laptops last longer - these are some of the benefits of instant clock speed reduction. Disadvantages of down frequency technology? They don't exist at all!

Why exactly 800 MHz?

This minimum frequency is convenient for both processor makers and motherboard manufacturers, along with other computer equipment. The standard 800 megahertz as a reduced frequency of a computer is like 220 outlet volts and 50 of the same outlet hertz.

Moreover, operating systems are “more comfortable” working with sufficiently fast processors. The minimum requirements for Windows 7 (and the modern "tens") are still the same 800 megahertz. If the CPU "throws" the frequency to a lower one, the OS can mistakenly "think" that there are not enough resources for its comfortable work - and stop working.

Modern clock frequencies: there is practically no “nominal”!

Finally - about the "nominal frequency" of the processor. This characteristic is declared by the manufacturer for each processor model. Let's say a modern Intel Core i5 6500 (Skylake generation) has:

• 4 cores;
• 6 megabytes of L3 cache;
• built-in video card (graphic core) of the HD 530 generation;
• 14 nanometer transistors (the smaller, the better and more modern)
• "base" clock frequency of 3.2 gigahertz (= 3200 MHz);
• heat dissipation - 65 watts (the less - more economical and "colder");
• a bunch of great technologies like Intel SpeedStep.

It is this floating frequency technology called Speed ​​Step that is responsible for lowering the frequency to 800 megahertz. But even more interesting is that the same technology automatically “overclocks” the processor from a nominal 3.2 up to 3.6 gigahertz when the computer needs more power.

Processor frequency monitoring: base - 3.33 MHz, but at the moment, Intel SpeedStep technology has increased the frequency to 3.46 MHz. During idle, the frequency will drop to 800 MHz.

Typical Speed ​​Step scenarios:

• the processor is not really loaded (a text editor, an audio player and a couple of instant messengers are working) - the frequency drops to 800 MHz;
• several tabs are open in the browser, the processor needs more power on 1-2 cores out of 4 - it is working at a nominal 3 gigahertz;
• The CPU is loaded at full capacity - you can increase the frequency to 3.6 GHz (if 1 core is loaded) or at least up to 3.3 GHz (if all 4 cores are loaded). Yes, power consumption will increase - but within acceptable limits. And most importantly, a complex resource-intensive task will be completed faster (and then it will be possible to lower the frequency to the “energy-saving” 800 megahertz).

Once again, we note: switching frequencies is automatic, user reaction is not required. The rise or fall in frequency is an almost instantaneous process: faster than the blink of an eye. Moreover, with each new generation of processors, the frequency switching moment decreases - in the short term, the delay time will be reduced from 50-100 nanoseconds to 25-30 ns.

Results

Frequencies are reduced not only for processors, but also for video cards and other components computer systems. Reduced to save electricity and reduce heat generation. This is a normal procedure, which not only should not cause concern - it is a reason to be proud scientific and technological progress humanity and the evolution of central processing units in particular.

The article is useful for those who are choosing an antenna and equipment for amplifying a mobile 3G and 4G Internet signal, or a repeater for amplifying cellular communication.

The 3G / 4G signal frequency is the initial parameter in choosing an antenna. For example, you may not know the location of base stations on the ground - just catch the signal and determine the direction by the level by turning the antenna. But if you do not know the frequency, then the signal can not be caught at all.

Important! All testing is recommended to be performed at the point of the planned installation of the antenna (with a laptop + modem, ideally on the roof), because. indoors, the modem may not catch a signal in the 2600 MHz (4G) band, but for an outdoor antenna it is the most effective!
Due to the fact that the methods for determining the GSM/3G/4G/4G+ frequency differ, we will consider them separately.

1. Mobile method:

1. Android:
Attention! Turn off WiFi!
To test the frequency, the built-in technical menu "Netmonitor" (Network Monitor) is used, which in each smartphone model is called by a personal code. A list of Android phones and codes such as *#0011# or *#*#4636#*#* or *#*#197328640#*#* can be found

For Samsung:Turn off WiFi, and select 3G or 4G LTE mode. In the phone number input field, dial the combination: * # 0011 #, after which the phone will enter the service mode with a signal report from the BS you are connected to.

3G parameter values:

1. uarfcn(may be referred to as RX): Channel number that specifies the frequency. If the value is from 10562-10838, then you have 3G/UMTS 2100 MHz. If 2937-3088, then this is 3G/UMTS 900 MHz. In our case uarfcn = 10687 , hence the frequency 3G = 2100.
   
2. EcIo (Ec/Io or Ec/No): the ratio of the signal level to the noise level in (the higher the indicator, the better). The lower the load (the network is free), the closer the EcIo indicator tends to 0. With an increase in the number of subscribers, the throughput decreases - the ratio worsens up to -12..-14 dB, after which, according to the settings, 3G-> 2G switching can occur. Perhaps you should choose a direction to a freer tower. For 4G, this parameter is denoted as CINR .
   
3. RSCP:(Reference Signal Received Power) The strength of the received signal that your device receives when connected to the BS. -70 good, -100 bad.
   

4G LTE values:

1. Band: The frequency at which the 4G network tower operates. There are 3 in total. In our case Band:7 is the frequency 2600 MHz , if Band:3 then 1800 MHz, and Band:20- frequency 800 MHz. (Full list frequency bands.)
2. RSSI: Basic value of signal strength At values RSRP= -120 dBm and below LTE connection may be unstable or not available at all.
3. CINR: The ratio of the level of the useful signal to the air noise. Everything is simple here: the higher this value, the better the signal quality. If a SINR below 0, then the connection speed will be slow, as this means that the received signal has more noise than usefulness, which increases the likelihood of losing an LTE connection.

1.1 ADDITIONAL APPS FOR ADNROID:

Here, without a doubt, it is worth noting the CellMapper application that is capable of identifying and displaying on the screen the value of the operating frequency, information about the tower, neighbors, displaying the tower on the map ( must enable the option“Calculate GSM/UMTS/LTE Frequencies”) As we already wrote, the frequency is displayed as Band. The signal level is indicated in the field Reference Signal Received Power(RSRP). To work with the application, you must pass a free registration on the site.

1.2 Signal level display in standard USB Modem applications:

Information about the signal level is contained on almost any 3G / 4G LTE modem, for this it is enough to study the menu.

2. Testing using a USB modem (the most reliable):

Nonetheless , the most effective and inexpensive and reliable way to establish the carrier frequency of the Internet signal is a computer + modem that has a HiLink interface or Stick . Below is the test methodMDMA program using firmware Stick which usually stands on purchased locked modems of Russian telecom operators.

2.1 Working with the MDMA program:

(communication parameters display window)

Important! Before starting the program MDMA (Mobile Data Monitoring Application) it is necessary to close all the "native" programs of the usb modem !!!

After launch, the program will display the signal level, air noise, and base station parameters. Here, our goal is to determine which 3G & 4G LTE frequency the operator is operating on., by sorting them out. Pushing a button"Band Config" we will call the window in which we perform simple actions:

1. Change the parameter "Automatic" to "Custom"
2. 3G put a tick on to start on UMTS 2100 press "OK" and follow the signal strength and network registration in the main window. If the operator name appears in the field, and a checkmark appears next to "Registered", then your operator works on the frequency UMTS 2100. If registration fails, return to the leading step, uncheck UMTS 2100 and install on UMTS 900.
   
3. If the program generated an error when choosing a parameter (for example, UMTS 900), then your modem cannot work in this standard.
4. On 4G LTE network sequence and logic action similar to 3G, except that they are all held in the right area (LTE Bands).

2.2 Analysis with Hilink universal modem:

Here, the actions are similar to the previous example, the determination of the range is also carried out by enumeration of frequencies.

Go to Settings -> Network settings, then select the standard (LTE, UMTS or others), set the mode to "Manual" and start ticking the bands, checking the strength of the RSSI signal on the parameters page.

Range definition in 3G networks:

Page displaying signal parameters

It should be noted that there are cases when the operator broadcasts the Internet immediately intwo bands at the same time. For example, in the city of Chekhov M.O. Tele2 in 4G operates in parallel on 800 and 2600 MHz. The RSSI power is different, but the main frequency remains 800 MHz. If you want to provide a higher speed and use both frequencies for reception, you should use a multi-standard antenna that supports operation using LTE-A technology simultaneously in 2 bands.

What is 4G (LTE)? According to Wikipedia, LTE (literally from English Long-Term Evolution - long-term development, often referred to as 4G LTE) is a wireless high-speed data transmission standard for mobile phones and other data terminals (modems, for example). He increases throughput and speed due to the use of a different radio interface along with the improvement of the network core. The standard was developed by 3GPP (consortium developing specifications for mobile telephony). The LTE wireless interface is not compatible with 2G and 3G, so it must operate on a separate frequency. In Russia, three frequency bands are allocated for LTE - 800, 1800 and 2600 MHz.

LTE FDD and LTE TDD

There are two types of LTE standard, the differences between which are quite significant. FDD - FrequencyDivisionDuplex (incoming and outgoing channel frequency separation) TDD - TimeDivisionDuplex (incoming and outgoing channel time separation). Roughly speaking, FDD is parallel LTE and TDD is serial LTE. For example, with a channel width of 20 MHz in FDD LTE, part of the range (15 MHz) is given for downloading (download), and part (5 MHz) for uploading (upload). Thus, the channels do not overlap in frequency, which allows you to work simultaneously and stably for downloading and uploading data. In TDD LTE, the same 20 MHz channel is completely given up for both downloading and uploading, and data is transmitted in one direction or the other in turn, while downloading still has priority. In general, FDD LTE is preferable because it works faster and more stable.

Frequency bands LTE, Band

LTE networks (FDD and TDD) operate at different frequencies in different countries. In many countries, several frequency bands are operated at once. It should be noted that not all equipment can work on different "bands", i.e. frequency ranges. FDD ranges are numbered 1 to 31, TDD ranges 33 to 44. There are a few additional standards that have not yet been assigned numbers. Specifications for frequency bands are called bands (BAND). In Russia and Europe, band 7, band 20, band 3 and band 38 are mainly used.

In Russia, four frequency ranges are currently used for 4th generation networks:

As an example, I will give the distribution of frequencies among the main Russian telecom operators in the LTE2600 (Band7) band:

As you can see from this diagram, Beeline got only 10 MHz. Rostelecom also got only 10 MHz. MTS - 35 MHz in the Moscow region and 10 MHz throughout the country. And Megafon and Yota (this is the same holding) got as much as 65 MHz for two in the Moscow region and 40 MHz throughout Russia! Through Yota in Moscow, only Megafon works virtually in the 4G standard, in other regions - Megafon and MTS. Television (Cosmos-TV, etc.) will operate in the TDD range throughout Russia, except for Moscow.
For the full frequency distribution of mobile operators in Russia, see.

4G LTE networks in Russia

The frequency distribution among operators in the regions of Russia can be found.

For those who find it difficult to remember the band-band numbers or do not have a suitable reference handy, I recommend a small android application RFrequence, a screenshot of which is given below.

LTE categories

Subscriber devices are classified into categories. The most common today are devices of the 4th category CAT4. This means that the maximum achievable speed mobile internet for reception (downlink or DL) can be 150 Mbps, for transmission (uplink or UL) - 50 Mbps. It is important to note that this is the maximum achievable speed under ideal conditions - the main ones are that you are not far from the tower, there are no other subscribers in the cell except you, optical transport is connected to the base station, etc. The most common categories of subscriber devices are shown in the table.

The table needs some explanation. "Carrier aggregation" and "additional technologies" are mentioned here. I'll try to explain what it is.

Frequency aggregation

The word "aggregation" in this case means a union, i.e. frequency aggregation is the combination of frequencies. What this means - I will try to explain below.
It is known that the rate of transmission reception depends on the width of the transmission channel. As we saw from the table in the previous section, the channel width for downloading, for example, MTS is 10 MHz in the Band7 band (except Moscow), for uploading it is also 10 MHz. To increase the download speed, the operator redistributes the frequencies he purchased in the ratio of 15 MHz for download and 5 MHz for upload. Other providers do the same.

One day, one of the developers came up with a bright idea - what if the signal is transmitted not on one carrier frequency, but on several at the same time. Thus, the receive / transmit channel expands and the speed theoretically increases significantly. And if each carrier is also transmitted according to the MIMO 2x2 scheme, then we get an additional gain in speed. Such a reception-transmission scheme is called “frequency aggregation.” It is this scheme that is used by the Internet 4G + or LTE-Advanced (LTE-A).

The table indicates that for Cat.9, the transmitter and receiver must be able to transmit and receive a signal on three carrier frequencies (in three bands) simultaneously, the width of each channel must be at least 20 MHz. For Cat.12, it is additionally necessary that the antenna devices be connected according to the MIMO 4x4 scheme, i.e. in fact, you need 4 antennas on the receiving and transmitting sides. Mysterious symbols 256QAM mean a certain type of signal modulation that allows you to pack information more densely. Those who wish to get acquainted with this topic in more detail can begin their acquaintance with the material in the article on Wikipedia and with the links there.

Receiver categorization

The frequency aggregation scheme is being actively developed by Russian providers, many agreements on the mutual use of frequency bands have been concluded, and the antenna facilities of base stations are being reconstructed. However, there is one problem - on the receiving side, the subscriber must be able to receive a signal at several carrier frequencies simultaneously. Not all smartphones, tablets and modems support frequency aggregation and therefore cannot work in 4G+.

Starting from 2016, the documentation for smartphones indicates the frequency bands (bands) and the LTE category in which they can work. For example, for a smartphone released in 2017, Huawei P10 Plus, among other parameters, the following is indicated:

In addition, this smartphone has a built-in M IMO 4x4 antenna and a corresponding modem that allows you to process signals on two carrier frequencies at once. If your smartphone supports frequency aggregation, then the "setting" > "mobile network" tab will look something like this:

If so, then your smartphone supports LTE-A.

Thus, smartphone manufacturers began to catch up with mobile operators. Unfortunately, the same cannot be said for modem manufacturers. Until now, the most productive modem gives maximum speeds of 150/50 Mbps, i.e. belongs to Cat.4. So far, this circumstance is not too upsetting, because. such speeds, if achieved in practice, are to be admired. However, production mobile routers seems to be starting to catch up with smartphones. Cat.6 routers from Huawei and Netgeer began to appear on the market (does not support Russian bands). So the Huawei E5787s-33a router can be bought on AliExpress for about 10 thousand rubles.

It must be said that real speeds achieved in the 4G+ mode are far from the declared ones, but they are much higher than in the simple 4G mode. The author conducted a series of experiments in Moscow, where it is not difficult to find LTE-A (Megafon operator), with a Cat.12 smartphone, the results of which are shown in the screenshots. The first screenshot is the speeds for LTE-A (frequency aggregation is enabled), the second screenshot is for LTE (frequency aggregation is disabled). I note that for some reason, when taking a screenshot, the plus sign disappears from the 4G + icon. Why - I don’t know, during testing there was a plus - see the screen.

Six measurements were taken for each mode. Speeds with frequency aggregation turned on are on average noticeably higher, although not by several times. The measurements were carried out near the tower, during the day.

Those wishing to experiment with LTE-A

If LTE-A appeared in your area, as you saw by measuring the frequencies of your chosen operator (the provider distributes the Internet at two frequencies, for example, LTE800 and LTE2600, i.e. uses a combination of B7 + B20) and your hands are itching to try what it is, then you can try to use a scheme of two MIMO antennas with diplexers.

After launching the application, go to its settings and check the box "Detect GMS/UMTS/LTE frequencies".

Then the main screen should display the information you are interested in about the frequency range used.

In our case, the smartphone connected to the Tele2 network using the 4G standard at a frequency of 1800 MHz (band 3).

The economic situation and the inability to fully use the 800 MHz band are forcing operators to actively develop 4G in the 1800 MHz frequency band. Moreover, most experts believe that by 2020 up to 50% of all coverage will be provided precisely by LTE 1800. Economic efficiency this range compared to 2600 MHz is much higher, and the costs are minimal. About how operators are engaged in "smart refarming" of GSM in LTE in practice, what advantages and disadvantages this brings, we found out from technical specialists MTS in the Urals.

Currently, 4G networks in Russia operate in 83 out of 85 regions. Moreover, in the vast majority of territories, LTE operates in the 2600 MHz band. And only 15 regions have test or commercial networks 4G 1800 MHz (Moscow, St. Petersburg, Leningrad and Tula regions, Krasnodar Territory, Bashkiria, Tatarstan). In the Urals, there are examples of commercial use of this standard in the Sverdlovsk and Kurgan regions, Khanty-Mansi Autonomous Okrug, Yamalo-Nenets Autonomous Okrug (Motiv operator), as well as in Chelyabinsk region(MTS). And if in the case of "Motive" the reasons for using the GSM spectrum are clear - the company does not have a license to use frequencies of either 800 MHz or 2600 MHz, then MTS's activity may seem strange. Although the oddity in this case is understandable.

Distribution of LTE networks in the world by bands (analysis of 400 largest networks LTE, OVUM and GSMA data):

Here are the reasons for such activity given in the MTS itself. First, the economy. LTE 1800 is much cheaper and more efficient.

The coverage area of ​​a base station operating at "voice" frequencies of 1800 MHz is four times larger than that of equipment in 2500-2700 MHz, and the use of this equipment for the development of data networks will allow as soon as possible deploy networks, because the same area can be covered by fewer base stations. At the same time, the LTE-1800 signal penetrates better into enclosed spaces than the signal of base stations operating in higher bands. The increased range of radio coverage makes it possible to provide a high-speed 4G network to remote settlements, highways, as well as areas with frequency restrictions, - says Konstantin Kubantsev, Technical Director Chelyabinsk branch of MTS.

Spectrum aggregation of 1800 and 2600 MHz, in the presence of a 10 MHz bandwidth in each of the two bands, allows increasing peak data rates from 75 Mbps to 150 Mbps, and in the case of aggregation of three carriers at once - up to 225 Mbps. In April 2015, MTS tests in Bashkortostan at frequencies of 1800+2600+800 MHz with a total bandwidth of up to 35 MHz demonstrated peak speeds of up to 260 Mbps.

According to estimates by telecom equipment manufacturers and companies providing a radio network optimization service based on geolocation of subscribers, up to 80% of traffic is generated indoors. This fact clearly gives an advantage to the 1800 range over 2600 MHz. The room penetration loss for 1800 MHz is significantly lower than for the 2600 band. Traffic will be collected better by the band with better penetration. The difference between WCDMA2100 and DCS1800 is quite noticeable, but due to the more sensitive 3G terminals on average, the difference is leveled.

The LTE-1800 standard supports up to 90% of LTE device models from leading manufacturers, including Apple, Samsung, HTC, Huawei, LG, Nokia, Sony, ZTE and others. With its development in Russia, owners of gadgets that do not support other LTE bands common in the country, such as iPhone 5, iPad mini, can also use 4G Internet.

If we continue the comparison, then according to Konstantin Kubantsev, LTE-2600 aggravates the already tense situation with the search for additional objects on which equipment is required to be installed. "In cities, there are very few buildings that we can go to and get permission to install equipment from the owners. We are constantly faced with refusals. Negotiations can take more than one year."

As a result, the company decided that LTE-2600 will be used in the largest cities in areas of the greatest load on Internet traffic. True, in this case, it is necessary to resolve issues related to ensuring a stable signal indoors, including using indoor coverage.

In other cases, LTE-1800 will be used. Under it, you do not have to change the existing infrastructure, make serious investments in the construction of new base stations and spend a lot of time.

Distribution of income from Russian mobile operators by types of traffic:

As a result, the main volume of base stations in the regions in a few years will fall on dual-band networks - 1800/2600 MHz or LTE800/2600 MHz, depending on the availability of frequency resources in each particular region.

The second reason for the growth of interest on the part of MTS is the restriction on the use of the 800 MHz band. Despite the fact that the operator has received the appropriate frequency assignments and is already paying for the lease, their implementation is hampered by the operation of missile defense systems, as well as the operation of military and civilian airfields. Existing rules do not allow the use of frequencies within a radius of 40 km from airports. Operators all over Russia face this problem to the same extent.

Questions of the full use of the 800 MHz band are quite acute. We are actively discussing problems with the Ministry of Communications. Literally, yesterday, as part of our communication, our proposals were handed over to Deputy Minister Dmitry Alkhazov, who oversees these issues in the government. He promised to help. Well, in the meantime, we are trying to work in the conditions that we have now, - says Konstantin Kubantsev.

When asked why the Chelyabinsk region became the first region in the Urals, where the operator began to massively launch LTE-1800, the company replied that a year ago it was in the Southern Urals that the complete network upgrade was completed. During this time, Motorola equipment, which had been operating for almost 10 years, was replaced by Ericsson of the most modern generation with widespread support for LTE-1800. Not a single old amplifier, switch or switch remained on the network. At the same time, the capacity of the backbone network was expanded.

All this allowed us to use a multi-standard 3G/LTE network. Moreover, priority for data transmission will be given to LTE. Thus, we will offload our 3G networks, - says Konstantin Kubantsev.

Under LTE-1800 in the Chelyabinsk region, MTS allocated a 5 MHz band out of the available 15. According to the operator's technical specialists, this band is enough for the existing number of 4G subscribers. At the same time, the quality of the 2G network and its capacity will not suffer. In the future, the company will analyze the possibility of increasing the frequency band to 10 MHz in each specific locality.

As for 4G sharing with Beeline, MTS emphasized that the agreements concern exclusively LTE800/2600 MHz networks. Only the company's own subscribers will have access to LTE1800.

At the moment, the dual-band network is already operating in twenty settlements Chelyabinsk region, in particular, in Zlatoust, Miass, as well as in small towns such as Ozersk, Troitsk, Satka, Yemanzhelinsk, and in places summer holiday residents and guests of the region - on Lake Uvildy and others. Also in 2015, the LTE-1800 network will be launched in Chelyabinsk and Magnitogorsk to improve 4G coverage inside buildings.

In the near future, MTS is going to introduce the Single RAN (Single Radio Access Network) platform with the possibility of organizing coverage of all GSM, 3G and LTE standards using one base station.
