Recently, choosing a tablet or a mobile phone can be accessed to the LTE incomprehensible designation. Moreover, it is presented as well as supercopiness from a fantastic hero. Many mobile operators, too, with Paphos broadcast on support for 4G format networks. Let's look at what LTE is in, or a smartphone. And in general, is it needed by LTE in the tablet?

The LTE standard (it is 4G, the fourth generation network) is deciphered as "long-term development". He collected all the best of the wireless data transmission area using the modulated signal and technology of modern local networks. It uses frequency modulation to generate a signal. Simultaneously use packet data transmission. This allows you to achieve several advantages at once:

1. Higher resistance to interference;
2. Increasing the range of stable communication;
3. It is possible to use data packaging;
4. It applies less redundancy of transmitted packets;
5. Significantly expands the channel bandwidth.

Testing a new communication standard has shown that 4G allows you to achieve a total bandwidth of 1 GB / s for one device and a transmission range up to 100 km in case of emergency. Such data were obtained by applying special equipment High power.

Rising indicators that like the user

If you briefly answer the question, which means LTE, then we can say that by using the new standard, the buyer receives a really high data transfer rate. So high that it can "shut up for the belt" suggestions of some cable Internet providers. For example, the maximum transfer rate in 3G networks is 42 megabits per second. Really, the user receives only 2, a maximum of 3 MB / s. This happens due to the download of the mobile network and quite a long response time.

Standard 4G hits all these indicators. Already, at the dawn of development of this class, MegaFon users or Beeline users in Moscow can receive data at a rate of 20 Mbps. And this is far from the limit. A very low response time and transmission stability makes the use of LTE indistinguishable from cable. A smooth transmission of high-definition streaming video is provided, not to mention the quality of the connection in Skype rises to unprecedented heights.

A little about the devices

If you want high speed when using the network, but it leads to buying a new expensive tablet, then you should first answer the question: LTE module - what is it?

In fact, everything is not so scary. Constructively this is the same digital modem with new functional abilities. If there are no them in the tablet, you can easily use external. MegaFon and MTS companies are already offering such devices that can use networks of all formats. The Scartel provider sells 4G modems that work on its networks and networks of other FDD format operators.

LTE module or modem can be used with desktop PC. This is an easy access for those who use a lot of stationary equipment (at work, at home, laptop at the cottage, on the road) and wants to get a high data transfer rate.

Current development and some underwater stones

It is worth noting that the introduction of 4G network networks is associated with high expenditure on equipment and network information support within the coating. Therefore, everything is slow. Today, 4G exists in large cities, such as Moscow, St. Petersburg and so on. Slowly, but it is true to distribute to other regions. If you are going to buy a tablet or laptop with LTE support, then consult local mobile providers, whether such a function is ensured.

Another danger from which the user may encounter is incompatibility of standards. Despite the fact that the LTE module works on a clear technology, frequency bands and signal forming methods differ in different countries. Therefore, such popular shopping paths, like eBay, Amazon and different mediators to purchase goods from Europe or China, can play a cruel joke. The tablet, equipped with LTE imported standard, simply will not work in the mobile networks of the post-Soviet space. You need to buy a device-oriented device in a particular country.

However, everything is not so gloomy. When buying, the user receives a device that can work in the last generation networks. In addition, it is completely compatible. The 4G module will also confidently work on the network and old 2G EDGE / GPRS networks. There will be no problems with communication.

Buying a tablet with LTE, you can get guaranteed technical compliance with the latest achievements of communication. LTE standard is not in vain called "long-term development". Consider in more detail what it means.

LTE Infrastructure Building Prospects

So far, 4G format networks are reduced to the data transfer structure for a mobile device. However, the widest bandwidth and the possibility of building a network is such that global integration is expected in the future. LTE networks Almost all will be united:

• cell phones
• tablets and laptops
• multimedia devices
• security and Signal Systems
• video surveillance structures cities
• road Control Services
• ticket service, services
• online banking, ATMs and payment terminals
• emergency services, including with automatic alert.

You can continue for a long time. In a single digital space, everything will be associated with LTE networks in the future, including household appliances. For example, it is already possible to display the "video signs" signal to the tablet and always confident that everything is in order with the child. A few years later, this will be perceived as natural as the inclusion of light with the onset of darkness.

Answering the question: "What does LTE mean in?" You can say simple. By purchasing a device with LTE, the user gets the opportunity to keep up with the times for a long time. This is a truly new communication standard that will develop and be used for a very long time. He has every chance of becoming a means of global communications.

Due to the fact that there are more and more smartphones in the Russian market with a built-in LTE module, many are wondering - what is LTE in the smartphone? In order to answer this question most clearly, you need to understand what LTE is and what advantages this technology has. After all, knowing the answer to these questions, even the most distant user mobile communications Will be able to understand what advantages LTE smartphone has.

1. LTE technology and its features

Modern technologies do not stand still. In particular, this concerns mobile technologies. If you recall all mobile technology available to simple subscribers, some regularity can be distinguished. Each communication generation, starting with 2G, has a certain time interval. That is, 2G technology was developed in 1990, and it was integrated only in 2000. Similarly, 3G - developed in 2000, and fully began to work only in 2010. Now it came to a turn of the fourth generation of communication. Already today we can observe a gradual transition from 3G to 4G. And it is LTE and is the same technology that allows this transition smoothly and unnoticed for subscribers.

LTE is a fourth-generation technology technology. Such mobile communication technologies that can provide subscribers to subscribers the speed of an Internet connection of at least 100 Mbps will be available. The main difference of this technology consists in high data transfer rates, which in the theory is 300 Mbps when receiving information (download) and 170 Mbps at arrival (UPLOAD). However, given the novelty technology and the fact that it is only implemented, the actual data transfer rate differs from the theory and is about 100 Mbit / s when receiving a signal and 50 Mbps at return.

Thus, it becomes clear that LTE smartphones allow the user to have access to a high-speed Internet. Thanks to this, subscribers receive a lot of new, absolutely not limited features. For example, high-quality double-sided video call, watching films online in FullHD format and so on.

Besides technology LTE. Implemented on the 3G network and allows you to use the already available infrastructure. This makes the transition from 3G to the fourth generation of communication more smooth and invisible to subscribers. In addition, in the overwhelming majority of cases, smartphones with LTE are able to work in third generation networks, and even 2G. In other words, even if the subscriber's exit from the LTE coverage area, the device automatically switches to 3G mode without loss of communication.

1.1. LTE communication modes

In addition, the feature of LTE technology is that it is capable of working immediately in two communication modes:

• FDD is a bilateral communication mode with frequency separation of signals. That is, downward and upstream information flows have different frequencies. This achieves higher stability of the established connection and high connection speed. In this case, the number of channels in both directions is equal.
• TDD is a bilateral connection with the time separation of signals. That is, the bond is implemented by temporary sealing downward and upstream data channels on one carrier frequency. The advantage of this communication mode is that it allows you to more optimally use the resources of radio lines. At the same time, the number of time intervals in the downstream and upstream communication channels is different.

Already today, understanding the need to combine these regimes, manufacturers mobile devices Made terminals supporting both modes. Moreover, the complexity device having a combined terminal is not significantly different from simple device FDD.

2. Smartphones with LTE for Russia

Given all the advantages of LTE technology, it becomes clear that the smartphone with LTE is able to provide the user to the mass additional features and higher quality of communication, as well as the speed of the Internet connection.

In addition, mobile operators providing LTE services clearly understand that the availability of mobile subscriber devices, in particular LTE smartphones, directly affects the demand of such services. This is explained simple rule - Demand creates supply. After all, what more people They can afford to purchase a mobile device with LTE, the higher the demand for this technology, the more, accordingly, technology will be developed faster and implement.

Understanding this relationship, the largest mobile operators created a strategic partnership and filed a request for a decrease in customs duty on the import of mobile devices, in particular smartphones. This will reduce their cost and make them more accessible to Russians.

However, there is one nuance. Not every smartphone with support for LTE will be able to work in Russian networks. This is explained by the fact that at the moment devices are available with LTE modules configured to a certain frequency. For example, if the smartphone is set to the frequency of 2100 MHz, then in Russia it will not work, since the LTE networks are built in the frequency bands of 791-862 MHz and 2500-2700 MHz. In the specifications of the device, the supported frequency is required.

To date, units of smartphones models can be operated in Russia, including:

• Nokia Lumia 920;
• LG Optimus G;
• LG Optimus F5;
• Sony Xperia V;
• Sony Xperia SP;
• SAMSUNG GALAXY EXPRESS;
• Alcatel Idol S;
• HTC One SV;
• BlackBerry Z10.

However, even these models do not support all frequencies. In most cases, they can only work under the lower range. In order to know exactly what frequencies does the smartphone support, see specifications. In addition to these devices, on russian market There are other smartphones. With the development of technologies, new and new models appear, capable of working in Russian LTE networks.

3. Benefits LTE smartphones

Given all the advantages and features of LTE technology, all the advantages of LTE smartphones become obvious. LTE support smartphones are not easy comfortable tool For traveling vast space. First of all, these are multifunctional devices that allow you to solve a wide variety of tasks that may be related to both multimedia (watching FullHD movies, listening to music, image processing, and so on) and with the Internet (video conferencing, online presentation, high-quality communication and high internet speed). All this becomes available to each owner of the LTE smartphone.

In addition to ordinary models in the Russian market, you can meet two-minute smartphones with LTE. They allow you to use the fourth generation link from different operators. At the moment it is a huge advantage, since still LTE networks do not cover the entire territory of the country. Different operators cover different cities. So in those cities in which there is no LTE cover from MTS, there are biline or megaphone networks. Here in these cases, smartphones with two SIM cards are an excellent solution.

One more very important advantage It is that LTE smartphones for Russia are able to work not only in the fourth generation networks. They support the connection of the third, and even the second generation. Thus, the subscriber always remains in touch. At the moment there is an automatic transition technology between networks. In other words, when leaving the LTE coverage zone, the smartphone automatically goes into 3G mode without loss of communication and unnoticed for the user.

4. Available LTE Smartphone from Samsung: Video

LTE for modern smartphones is a significant expansion of opportunities. This is a lot of fascinating entertainment. For example, multiplayer online Gameswhich used to be available only when Wi-Fi connect is available today to each LTE subscriber. In addition, the smartphone itself can be used as a Wi-Fi router, distributing the Internet to all others. That is, if there is no LTE module on the laptop, you need to connect your smartphone to the Internet via the 4G network and enable Wi-Fi access point in the settings. At the same time, high-speed Internet will be heard on your laptop, as well as other subscriber devices equipped with Wi-Fi module.

IN modern world high technologies Always stay in touch is not a luxury, but a necessity, therefore, for business people, smartphones with LTE are a real salvation, as they can create a video conferencing at any time and anywhere will be able to create any other tasks associated with Internet access and sending files. And given the compact sizes of such devices, they are always and everywhere you can take with you.

LTE, he is 4G LTE.is a perspective method of high-speed information transmission via GSM / EDGE and UMTS / HSPA protocols in phones. It is known that LTE is a standard that is intended primarily to increase the data exchange rate using mobile phones, PDAs and other interactive devices with the possibility of connecting to cellular mobile terminals.

What it isLTE 4 G. on smartphones? Being a "fourth generation of data generation" on phones, LTE is the logical development of an older data transfer standard - the third generation standard known as 3G.

The LTE standard was based on the concept of preserving the maximum change in the cost of transmission, with a concomitant increase in speed and the ability to promptly connect a variety of information services.

In other words, the creators of 4G LTE set a goal to develop a more advanced and at the same time a cheap methodology for transferring data to phones, which in addition would become the base for subsequent improvements and innovations. And, notice, 4G LTE fully satisfied their ambitions. It is truly to understand that this is LTE you can only using this technology for some time on your gadgets.

Characteristics of LTE technology

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

In addition, this 4G LTE technology allows radio frequency in the wide frequency range from 1.4 MHz to 20 MHz, and even supports frequency differentiation of channels (FDD), which causes the ability to use this protocol for a variety of auxiliary options, for example, for IP telephony, voice Exchange based on Volte technology and other "sweaty" batch gears.

It should not be noted that this technology LTE, by optimizing the architectural operations of the 3G network, allows you to connect even to a standard 5 MHz mobile cell to two hundred active subscribers. Thanks to this feature, the 4G LTE standard allowed not only to increase the available characteristics of 3G networks, but also to reduce the cost of data exchange, since it has now been required to ensure the radio exchange of the same number of devices.

Difference 4G from 3G

In addition to the above key features that are the logical development of the 3G, 4G LTE standards, 4G LTE also boasts unique features, in particular:

• The possibility of interaction with the E-ULTRA protocol;
• Conceptually new method for supporting the mobility of signal transmission, allowing radio exchange with a terminal moving at speed to 350km / h;
• Radio commutation of batch data;
• Previously inaccessible frequency spectrum ranges.

How can I connect to the LTE network

It is worth noting that the majority modern devices Supported LTE before its widespread implementation, and this is not an accident - the developers focused on the possibility of cooperation with old GSM / EDGE, UMTS and CDMA2000 client terminals (mobile phones, PDAs). What is this standard LTE we figured out, now learn how to use LTE on the phone.

However, to use all the advantages of this protocol "on full" still require the presence of a device supporting standard 4G, since otherwise the data transfer rate will be limited to the parameters of the client device, and not the power of the cellular tower.

Concerning software setup, any applications or utilities for interfacing with 4G LTE Network is not required - it is enough to register the terminal standard authorization data of the cellular operator. Simply put, if your phone went to the Internet in the territory of the Russian Federation using the 3G protocol, then "finding" 4G LTE will be connected to it without any participation on your part, and you will only be content with high-speed mobile Internet.

In contact with

It is actively developing, users each day offer more and more services and applications designed to make the life of the subscriber of cellular networks as much as possible. It is no secret that many wireless consumers regularly use resources on their gadgets almost every smartphone released now - with LTE support, it is mandatory requirement modern information century.

Brief History of Mobile Internet

So, the Internet has become an integral part of any modern smartphone. He helps check mail, chat in social networksYes, and just get the necessary information in a short time. Previously, the phone as a point of access to the network was extremely rare. It was associated with many reasons: the quality of the compound was left to desire the best, the speed of the Internet forced to be pretty renewed, moreover, the price was played an important role. Traffic on mobile devices was originally fairly expensive for an ordinary user of this type of communication. However, nothing is in place. The largest cellular network operators and manufacturers of gadgets quickly realized all the benefits of implementing and cheating progressive in the technical sense of Internet connection methods for users of mobile devices.

Four generation networks

What is LTE in the smartphone? We will conduct a brief excursion in the history of the development So, everything is quite well remembered GPRS. This technology of compounds with the World Wide Web required the non-light excerpt and was a fabulously expensive, so it was not popular. She comes to shift new technology, called the "Third Generation of Mobile Services", or 3G. This technical achievement began to be implemented in the 2000s. His a distinctive feature is a two-step connection, which allows you to increase to 3.5 Mbps. This means the ability to view on the smartphone of films, rollers and other volumes for the traffic of files. In addition, the quality of communication has increased, and the networks of this generation is possible a quick transition from a voice call to the further use of Internet surfing. But they replaced more developed networks - the fourth generation, or 4G. This newest technology allows you to access the worldwide network at a speed of up to 100 Mbps - that's what LTE is in the smartphone.

Principle of operation LTE

Now let's try to deal with the networks of the last generation, their support and the ability to use in various situations. Each generations of communication are changed for ten years, and new requirements are presented to them. What is LTE in a new generation smartphone? This is the possibility of a comfortable use of voice and video links and, importantly, it is high-speed Internet access. All other things being equal, explicit advantages are indisputable: Fast downloading information, large-scale file sharing, clear picture when viewing. All this is provided with a multi-line connection and packet data transmission. However, new generation networks have a limited coverage area. At the moment it is megacities, big cities And some capital of the regions of the Russian Federation. All new generation gadgets have support for LTE, but their price is quite high. Chinese smartphones with LTE are in constant demand - like cheaper, but with similar specifications. Now you can imagine what LTE is in the smartphone, and why it serves this generation of communications.

Today is wireless mobile Internet From cellular operators gaining increasing popularity in big cities. Thanks to him, each user can use the Internet and download information from the network in any part of the coating zone. Wireless Internet is also divided into different types Technologies. For example, there is an Internet generation 3G and generation LTE. At the same time wireless Internet LTE is made by the new technology today and has not yet entered tightly into our lives.

So, not everyone knows what LTE is and how to use it, as well as what significant innovations she brought. Consider more together this new technology.

Development of mobile networks and the appearance of LTE

The first Internet on the mobile phone can be considered the GPRS technology, which is also called the first generation technology. However, this technology had very low speed and a small coverage area, which made it difficult to use it. Then, in 2003, an EDGE technology appeared, which is considered to be the technology of the start of the era of the mobile Internet.

Often the EDGE technology is called "2G", which is translated as "second generation technology". Despite the fact that the speed of such an Internet has become much higher than GPRS, it still was low, and many sites had to upload for a long time, and about such a thing, how to watch a movie online could not be dreaming.

The next stage of the development of data technology has become the emergence of a third-generation wireless network, which is called "3G". Thanks to this new technology, it has become easy to use the Internet, and the connection has become more stable. Now users of this mobile network can download quick sites and even watch online video, which was impossible earlier. This technology is fairly distributed in our time. However, it successfully sends a new fourth-generation technology.

With the development of the Internet and mobile phones, a network was required, which is capable of transmitting data on the network even faster and at the same time decrease costs. Then the developers created the fourth generation network - "4G" or "LTE". The name is translated as "long-term evolution", which hints on long-term use of technology in the near future.

This technology has tremendous benefits compared to past generations and is actively entering our daily life.

Characteristics of LTE technology

4G technology allows you to transmit data on a wireless mobile network at a speed of up to 150 Mbps, which is currently the fastest transmission of data on the mobile network. With such fast speed any user can open sites instantly and very quickly download movies in best quality. In addition, you can watch even films in HD quality online without any problems.

4G coating zone is up to 100 kilometers, which is much more than 3G. Also 4g better uses the frequency range, reducing the effect of interference to the wireless network.

LTE technology was created in order to increase the data transfer rate, reduce the cost and reduce the delay in transmitting data packets. All these items The fourth generation network performs excellent. In addition, 4G lowered the costs of mobile operators 6 times compared with 3G technology, and, it means, it has reduced the cost of using the services for the consumer.

How can I connect to the LTE network

Almost all modern mobile phones are equipped with the possibility of using a fourth-generation wireless network, but older models do not support this technology. Connect to 4G through the mobile will not work. It is enough to activate the desired tariff plan at the cellular operator, which provides this service. However, it is important to remember that today the 4G network coverage area may not be everywhere. Mostly coverage area is in central regions Megacols. However, in the future it will change.

To connect 4G on the phone and tablet, you will need a special SIM card that can be bought in the offices of a cellular operator. In addition, the laptop will need another USB modem or a router through which data transmission on a laptop or computer will occur. Router or modem is also bought in cellular salons.

After the purchase necessary equipment It remains only to choose a suitable rate. All information on tariff plans can be viewed on the website of the cellular operator or clarify in communication salons, where you purchase a modem or router.
