What is LTE in a smartphone or phone?

LTE (from the English Long-Term Evolution – long-term development) is a standard for wireless high-speed data transfer for mobile devices (and not only) that work with data. Often referred to as LTE 4G.

LTE is an evolution of GSM / UMTS standards. The purpose of this communication standard was to increase throughput and speed using the method of digital signal processing and modulation, which were developed at the end of the last century. The LTE wireless interface is not compatible with 2G and 3G, and therefore should work on a separate frequency.

Where can I hear about LTE?

You can find out about LTE, for example, in the review of the next smartphone that supports this standard, or when buying a smartphone in the store, where the manager will assure you that you definitely need to purchase a device with LTE support. In part, he will be right, because if you have LTE in your smartphone and technology is supported in your city, you can transfer files at high speed using wireless Internet or, for example, watch movies in FHD-resolution directly on the Internet, if, of course, the device supports viewing Full HD movies.

LTE speed

The LTE specification is such that it provides download speeds of up to 326.4 Mbit / s, and the upload speed can reach 172.8 Mbit / s. Delay in data transfer is 5 milliseconds.

Features of LTE Technology

The range of an LTE station actually depends on the radiation power, while not limited in theory, but the maximum data rate depends on the distance from the station and the radio frequency. The limit for a speed of 1 Mbps is from 3.2 km (2600 MHz) to 19.7 km (450 MHz). In our country, many operators operate at frequencies of 2600 MHz, 1800 MHz and 800 MHz. The most commonly used band in the world is 1800 MHz..

LTE in Russia and in the world

According to various sources, at the time of writing this article contains more than 50% of the total population of Russia in the LTE coverage area. In some countries, this figure is an order of magnitude higher. For example, LTE implementation in South Korea reaches 97%, in Japan – 90%, and in Singapore – 84%.

The coverage area in Russia is constantly expanding, so we can expect that LTE technology in the future will be available almost throughout the country.

How to connect to LTE?

First of all, the subscriber needs to clarify whether his cellular operator LTE supports it. If it supports, then you need a smartphone with support for this technology. After that, the only thing the subscriber needs to do is simply connect to the mobile Internet and, if possible, the connection will be made using fourth-generation mobile communication (4G). Please note that far from everywhere LTE is supported even within the same city. For example, the coverage area may be relevant only for certain areas of the city.

In some cases, it is necessary to replace the old SIM card with a new one if it does not support new technologies. In addition, if you plan to use high-speed Internet, it is better to connect unlimited Internet, since at such a high speed the traffic is consumed very quickly and, most importantly, almost imperceptibly for the subscriber.
