What is 4G-network, and what advantages they give us

The development of the Internet has dramatically changed the world. Users receive not only free access to a variety of information, but also new opportunities for communication and entertainment. This was very important to have a quality Internet connection.

What is 4G-network, and what advantages they give us

Many internet users will still remember the first modems, had a top speed of 56 kilobits per connection per second. At the same time many had to not pay for the consumed traffic, and for the overall connection time, which was very profitable. Due to competition and the emergence of new technologies the situation began to gradually improve. Speed ​​is constantly growing, "povremenka" thing of the past. In addition to the wired Internet access services and began to offer mobile operators. The users become available GPRS protocol, EDGE, and then, finally, 3G, connection speed is ensured to 3.6 Mbit / s. Following came the intermediate standard 3,5G, or HSDPA (up to 14 Mbit / s). Finally, replace it soon must come universally 4G standard that allows the transfer of information at a rate of several hundred megabits per second. Advantages of high-speed communication can not be overestimated - users are available vast amounts of information, it goes back to wait for some time downloading "heavy" pages or a large amount of files. That convenience and saving time are the main advantages of 4G-networks. In addition, it is mobile telephony, which means the user can enjoy a truly high-speed Internet anywhere where there is a cellular connection. With the introduction of 4G mobile technology users will be available for Internet TV in HD quality. Video conferencing and video calls, too, become quite commonplace. With the ability to transfer huge amounts of 4G-network information will open up many new possibilities, most of which is even hard to imagine. For example, physicians can remotely perform operations using robotic operating disappear problem of simultaneous translation of foreign speech - modern programs can now translate it "on the fly", but imperfect relationship leads to a delay of the transfer receipt. It should be noted that at the moment there are several technologies competing for the right to refer to the use of 4G. This LTE, TD-LTE, Mobile WiMAX, UMB and HSPA +. Most mobile operators of the world tend to use LTE technology, that it will develop in Russia. Currently, the first 4G-speed networks based on this technology is in the order of 20 Mbit / sec., But in the future to increase the speed of 300 Mbit / sec.
