27.10.2015

In the previous article we already looked at third generation standards under the general name . However, communications of the fourth generation - 4G - are spreading rapidly. About the main standard in 4G this moment is LTE. Strictly speaking, LTE was not the first fourth-generation standard; the first widespread one was the WiMAX standard. Yota worked there for the first time, and some operators still use WiMAX. The maximum WiMAX speed is 40 Mbit/s, but real figures range from 10 to 20 Mbit/s.

But let's return to LTE. It is now the most widespread in the world in general and in Russia in particular. But what is 4G LTE? LTE (from English) Long-Term Evolution) is a standard for wireless high-speed data transmission for mobile devices. It is based on the same GSM/UMTS protocols, but theoretical and real data transfer speeds in LTE networks are much higher, sometimes even superior to wired connections!

LTE FDD and LTE TDD: what are the differences?

The LTE standard comes in two types, the differences between which are quite significant. FDD- Frequency Division Duplex (frequency separation of incoming and outgoing channels)
TDD- Time Division Duplex (time separation of incoming and outgoing channels). 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 download, and part (5 MHz) for upload. Thus, the channels do not overlap in frequencies, which allows you to work simultaneously and stably for loading and unloading data. In TDD LTE, the same 20 MHz channel is completely given over to both downloading and uploading, and data is transmitted to both sides alternately, with downloading still having priority. In general, FDD LTE is preferable because it works faster and more stable.

LTE frequencies

LTE networks (FDD and TDD) operate at different frequencies in different countries. In many countries, several frequency bands are used at once. It is worth noting that not all equipment can work on different “bands”, i.e. frequency ranges. FDD ranges are numbered from 1 to 31, TDD ranges from 33 to 44. There are additionally several 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.

Here is a list of frequency ranges for 4G LTE networks in Russia from the Big Five operators. There are also regional networks 4G LTE of local operators operating in other frequency bands, but their consideration is not necessary within the scope of this article.

The most important criterion, which is of particular interest to subscribers, i.e. users of 4G LTE networks, is the data transfer speed. And the speed primarily depends on the width of the frequency range of a particular operator, as well as the type of duplex used in the network. For example, for a 10 MHz channel, the 4G LTE speed will be 75 Mbit/s. It is with this nominal speed that the LTE FDD (band 7) networks of Tele2, MTS and operators operate. What about Megafon? And Megafon can afford more. Because several years ago there was a merger, or rather the absorption of Yota by Megafon, now Megafon has licenses for Yota frequencies, respectively, the maximum channel width can reach 40 MHz in the frequency range of 2600 MHz (band 7), which in theory gives as much as 300 Mbit/s! But basically the Megafon 4G network operates in a 15-20 MHz channel, which gives a download speed of 100-150 Mbit/s. After all, something must be left for Iota.

LTE-Advanced, or 4G+

The next stage in the development of 4G LTE networks is the LTE-A (LTE-Advanced) standard. Some operators call this technology 4G+ for marketing purposes, but this is completely incorrect. Those. in fact, it is LTE-Advanced that is truly 4G. Data transfer rates in LTE-A networks greatly exceeds conventional LTE. Main feature LTE-Advanced is an aggregation of frequency bands. A subscriber device with LTE-A support summarizes data transmission channels in different frequency ranges available to the operator. For example, combining several frequency ranges in the 2600 MHz band, a channel of 40 MHz is obtained, which gives a speed in the LTE-Advanced network of 300 Mbit/s. But this is far from the limit. If you add another 20 MHz from the 1800 MHz band, you get a 60 MHz channel (band 7 + band 3), and that’s already 450 Mbit/s! However, these are theoretical or bench speeds. In reality, they are of course much smaller, but nevertheless, LTE-Advanced wireless technology is quite close to wired speeds.

It is worth noting that all operators can aggregate different channels in different frequency ranges if they have the appropriate licenses and network infrastructure. The main task is to expand the frequency range. The wider it is, the higher the maximum speed, i.e. throughput networks. But of course there must be subscriber equipment that supports LTE-Advanced.

Prospects for 4G LTE

Despite the fact that the 4G LTE standard appeared several years ago, many regions of our country still do not even have 3G networks. So there is still room to grow. The world is already testing 5th generation (5G) networks, but in real conditions 4G LTE networks will dominate for a long time, fortunately operators are actively developing them.

In many cases, 4G Internet is not only an alternative to a wired connection, but also the only option, including an economically feasible one. Remote objects, the laying of wires to which involves certain difficulties or risks, and sometimes is completely impossible, also need to be connected. It is often possible to connect to 4G Internet even where there is no LTE network coverage. For this purpose special , which catch and amplify the 4G LTE signal. To choose the right antenna, you need to know which operator’s network you need to catch, at what frequency it operates, and also in what duplex mode (FDD or TDD). Our They will determine the type of signal, measure its parameters, and select the appropriate equipment to ensure fast and stable access to the Internet via the 4G LTE network.

At the very beginning of spring 2008, the International Telecommunication Union decided to start developing a new standard cellular communication– 4G. According to the adopted regulations, the main difference between the most modern 4G communication standard today and the 3G standard is the maximum, or, more precisely, peak data transfer speed.

So, for mobile devices in motion, this speed should be on average 10 Mbit/second, and for stationary devices - 1 Gbit/second (!). For comparison: wired Internet speeds from various providers range on average from 10–100 Mbit/second. That is, it is easy to calculate that the data transfer speed in the 4G standard should exceed existing standard speeds by 10–100 times.

History of the creation of the standard

The first “swallow” of the 4G standard was the LTE communication format, which allows you to increase the existing information transfer rate by approximately 10 times, that is, the peak data transfer rate for fixed communication devices is 100 Mbit/second. But even this speed is quite enough for high-quality viewing of TV shows in real time, and downloading a standard-sized movie to a mobile device may take no more than one or two minutes.

The LTE standard has received a lot of criticism regarding deviations from compliance with the stated information transmission parameters. LTE network coverage is currently unstable and largely depends on the capabilities of a particular mobile operator. As already noted, the maximum data transfer speed can reach 100 Mbit/second, but in real conditions this figure does not exceed an average of 42 Mbit/second. Of course, this is a decent indicator, but it clearly falls short of the speeds of one Gbit/second declared by the developers of the 4G standard. For this reason, some countries around the world are in no hurry to classify the standard as a progressive 4G technology.

An obvious disadvantage of the LTE standard is the low speed of information transfer. This problem can be solved by increasing the number of cellular operators and, accordingly, the services they provide.

Despite all the existing shortcomings, the LTE standard is clearly superior to existing 3G and especially 2G standards in all respects. The LTE standard, or more precisely, its structure, is fundamentally different from less technically advanced standards. First of all, the differences affected the base station subsystems and communication subsystems. The changes also affected the technology of data exchange between the user and base station. In the LTE standard, absolutely all types of information (be it voice or video) are transmitted in the format of unique packets.

Key components of the standard

Among the key components of the LTE standard are the following:

• The SGW (Serving Gateway) serves as a connecting link to the existing 2G and 3G networks of a specific mobile operator. This method allows you to significantly improve the quality of the network connection in the event of deteriorating reception conditions and increasing load on the network;
• gateway for connecting to other networks mobile operators PGW routes information packets to a specific operator's network;
• the MME mobility management node is designed to coordinate and, in fact, manage the mobility of network subscribers;
• The node for billing subscribers for the services provided PCRF, as the name suggests, is designed to calculate and provide an invoice to the subscriber of a mobile operator.

The basis of the LTE standard is the use of MIMO information transmission technology using the OFDM coding system. The operating principle of MIMO technology is based on the use of receiving and transmitting antennas different types, and the location of these antennas provides for an almost complete absence of correlation dependence.

Modern 4G networks mainly operate at a frequency of 2.3 GHz. Another common range is 2.5 GHz - a lot of work works at this frequency mobile operators Eurasia, Japan and the United States of America. There is also a frequency of 2.1 GHz, but it is not widely used due to the narrow range (from five to fifteen MHz). Thanks to the widespread use of broadband Internet in most countries of the Old World, the 3.5 GHz frequency receives new opportunities for the use of the 4G standard. This range will allow operators to painlessly, without purchasing and setting up expensive equipment cellular network use an existing and perfectly working frequency to transfer the LTE network to it.

If we consider the possibility of using frequencies for the standard mobile communications 4G, then we can confidently declare the suitability of the frequency range from 1.4 to 20 GHz.

While using the mobile Internet, you, of course, noticed that when established connection Different letters and abbreviations appear in the top quick access bar on the phone: H, H+, LTE, 3G, 4G and others. They indicate the type of connection on which the speed of data transmission and reception depends.

Explanation of symbols and characteristics of connection types

Knowing the meaning of the symbols and the basic parameters of each type of connection, you can understand what speed to expect with the existing signal level. In most cases, the mobile device itself selects the fastest available communication protocol and makes it possible to use the Internet through it.

Mobile device shows the type of network being used

Type to choose from network connection the following factors influence:

• the place where you are: indoors or at a great distance from large cities, the most modern and fast protocols (for example, 4G) may not be available, and the device will select the type of connection that will work, albeit slowly;
• tariff used: many tariffs do not provide for the use of the high-speed 4G protocol, allowing connection only to 3G and slower connection types;
• technical characteristics of the device: not all mobile devices support the maximum network access speed, so in order to find out how many megabytes per second your phone can send, you need to read the documentation on the official website of the manufacturer.

3G

Alternative names are 3rd Generation and UMTS. This is the most common Internet connection format these days. The number "3" denotes the third generation of communication protocols. Initially, the speed of this type of connection did not exceed 384 Kbps, but now, under favorable conditions, it can reach 21 Mbps. However, most often you will get speeds of up to 2 Mbps on your phone or tablet.

The advantages of the 3G mode include the fact that it is inferior in speed only to a 4G connection, but is available almost everywhere. But if you move faster than 30 km/h by car or train, the connection speed begins to decrease.

Speed mobile internet in 4G networks many times higher than in any other

H, 3.5G, H+, 3G+

Type H is an improved version of 3G, based on HSDPA - High Speed ​​Downlink Packet Access technology. H+, 3.5G and 3G+ are also add-ons to the 3G mode that use the HSPA+ protocol. They allow you to develop more high speed data transfer: under ideal conditions, when using a dual-channel version of the HSDPA protocol - up to 21 Mbit/s, and in the basic mono-channel version of the HSPA+ protocol - up to 22 Mbit/s. In reality, however, the speed in both protocols usually does not exceed 3.8 Mbit/s.

3.75G

This option is rarely seen as phones usually don't display it in the status bar even though they actually use it. The connection is carried out using the DC-HSPA+ protocol - an improved version of HSPA. Its maximum speed is two times higher than that of the H option - 42 Mbit/s, since it implements two-channel interaction. The best performance of networks of this type is comparable to the average performance of a 4G connection.

4G, LTE

4G (fourth generation networks) are the fastest available at the moment. But only if they implement the LTE (Long Term Evolution) protocol. Initially, 4G networks used WiMAX technology, and their speed did not exceed 40 Mbit/s. But today almost all telecom operators use the LTE protocol.

There are two types of LTE connections: LTE FDD and LTE TDD. Their main difference is the distribution of the available frequency range. But regardless of which version of the protocol is used, the data transfer speed can theoretically reach values ​​from 100 Mbit/s to 1 Gbit/s, and in reality - more than 40 Mbit/s.

4G networks, however, have a number of disadvantages:

• the cost of Internet access in them is higher than in 3G networks, so switching to a tariff that supports 4G is only worth it if you download large files or watch videos via mobile Internet;
• The coverage area, that is, the area where a 4G connection is available, is much smaller than that of 3G, so be prepared to be left without fast Internet if you go out of town.

The coverage areas of 3G and 4G networks in Russia are shown below. In the upper part there is a 4G coverage area, in the lower part - 3G. It can be seen that the 3G network coverage of the territory is much denser, especially at great distances from large cities.

3G network coverage is much denser

4G+, LTE-A

The 4G+ standard is the next stage in the development of networks based on the 4G protocol and supports LTE-Advanced technology. It allows you to combine used frequencies, resulting in increased connection speed.

The maximum speed depends on the specific implementation of LTE-A capabilities by the telecom operator. In some cases, you can get up to 450 Mbps, which is faster than wired connections.

G (General Packet Radio Service)

A very old standard, which at one time was positioned as an improved version of 2G - it was called 2.5G. It works using the GPRS protocol - an improved version of the GSM protocol.

This is, of course, the slowest type of communication of all those described, since its maximum speed does not exceed 200 Kbps. A regular website page without large quantity images and other media elements will take about a minute to load in this mode. But sometimes it is possible to connect to such a network in places where 3G and 4G are not available.

E (or EDGE - Enhanced Data Rates for GSM Evolution)

EDGE is not 3G yet, but is already closer to it. The second name of this option is 2.75G. This puncture appeared after G. It is capable of providing a maximum speed of about 300–400 Kbps.

Video: comparison of 3G and 4G connection speeds

Most fast internet these days it is available over a 4G+ or 4G connection. The second fastest option is 3G+ and H+, then H and 3G. The slowest options, which work a little faster than the regular 2G protocol, are G and E. At the same time, the coverage area of ​​​​the Internet using the most modern technology, is relatively small, and you can get a 3G, G or E network in most settlements countries.
