What is LTE in a tablet

The first computer appeared in 1971, but then it took up a lot of space, and each part required a separate room. This computer had a wired connection. But technology does not stand still and develops. This is why computers are constantly changing. Changes are taking place in different areas. For example, the size of a computer may change, and different types of gadgets may appear. One such variety, which appeared in 2002, can be considered a tablet - a tablet personal computer. It has all the functions available on a computer. The only difference is how the tablet connects to the internet.

To access the Internet, most tablets use wireless connections - wi-fi or mobile communication technologies. Mobile communications are of two types:

• 3G;
• 4G (LTE).

And if everything is clear with 3G, then many people have questions about LTE. Let's figure out together what it is.

LTE as a modern technology

What is LTE

Another name for LTE is 4G. This suggests that we have 4th generation technology, much more developed than previous ones. The abbreviation LTE stands for Long Time Evolution. This suggests that the creators of the technology plan to further develop it.

IMPORTANT! The main difference between the technology and 3G is the data transfer speed. The minimum information reception speed is 300 Mbit/s, and the minimum data transmission speed is about 170 Mbit/s.

One of the main goals that the creators had was to reduce the cost of data transmission and “unload” other networks. That is why a new wiring diagram was created.

Modes

Users of modern devices are provided with the Internet through the IP protocol and a large number of nodes. After all, the more complex the connection, the better it is. The technology can operate in two modes.

• TDD — data channels are compressed. And this allows you to improve the quality of your radio connection (cellular connection).
• FDD – signals are separated by frequency. This increases communication stability and improves connection quality.

Ranges

On the territory of Russia, work occurs in a separate range:

• 862 MHz to 791;
• from 2700 to 2500. No other devices operate in this range, so there is no interference with operation.

The throughput of such devices is about 150 Mb/s.

REFERENCE! LTE is much more resistant to interference than other types of communication.

Usage

Although the technology is currently only used for data transfer on mobile devices, the range will increase in the future. Gradually, the innovation will be integrated into many other devices, including:

• security and alarm systems;
• video surveillance systems;
• online banks;
• emergency services;
• various household appliances.

But currently, LTE is only available on mobile devices, and these devices have certain advantages.

Advantages of tablets with LTE

Advantages of LTE

• The main advantage of tablets with LTE over tablets with other types of communication is data transfer rates. Owners of devices with LTE can download movies, music faster and, in principle, use the Internet faster.Users can also create video conferences with a large number of subscribers and watch various videos in FullHD quality.
• Another advantage is tablets Doesn't use much battery power, as other types of connections do. Therefore the device discharges more slowly.
• The next advantage is in a wide coverage area. This is because tablets using this technology can also operate in 3G coverage. Thus, if a person leaves an area where LTE operates, he does not lose access to the Internet. Simply the tablet will automatically switch to 3G, and the subscriber will remain connected.

ATTENTION! The technology can be not only built into a tablet. There are also special modems. These modems are quite easy to use; you just need to insert them into the tablet. Then the tablet can be used not only in the city, but also in the country and on the highway.

LTE problems

In addition to the advantages, the technology in the tablet also has certain pitfalls.

• This is a very young technology and currently not available in all Russian cities. Therefore, before buying such a tablet, you need to consult with the mobile provider in your region.
• Incompatibility of standards. Devices with this technology in Russia operate in a certain frequency range. It is different from the European and US range. Therefore, you need to be very careful when purchasing a tablet from other countries or from sites like eBay and Amazon.

LTE is a very promising technology that has a bright future. This is why nowadays it is necessary to buy devices with lte.
