What is a 4G Network and How Does It Work
Mobile technology is constantly evolving. To be able to provide customers with competitive services, mobile operators are looking to use the latest advances in the field. The most promising area is now commissioning class networks such as 4G.
Development of the Internet world has changed the system beyond recognition. People are not only free access to a variety of information, but also can seek new opportunities for communication and entertainment. It is very important to have a quality internet connection. Thanks to 4G LTE network.
Wireless Internet in today’s world is an integral part of the business used by many large companies.

Internet users might remember the first modems, which had a top speed of 56 kbps. Due to competition and the emergence of new technologies, the situation began to gradually improve. The pace is constantly growing. In addition to the wired internet access services, mobile operators are offering much more speed to their respective customers for their ease of work. Among users are now available communication protocol GPRS, EDGE, and then, finally, 3G, ensured the connection speed of up to 3.6 mbps.

4G mobile network has been created on the basis of technologies of the fourth generation. They are characterized by a high rate of exchange of information, as well as improved voice quality. Unlike 3G network, this class use only packet data protocols (IPv4, IPv6). The rate of exchange is more than 100 mbps for mobile and more than 1 GBps for fixed subscribers. Transferring voice in 4G networks is through VoIP. Currently, there are two technologies considered to meet the requirements of Class B networks 4G i.e. LTE-Advanced and WiMAX (Wireless Advanced).

Development of technology for LTE, which is a prototype of LTE-Advanced, was started in 2000 by Hewlett-Packard. This technology is expected to be successful in near future all over the world because this standard can be applied to already existing mobile networks and supported by the operators of cellular communication. The first network based on LTE-Advanced was officially launched in December 2009 in the cities of Stockholm and Oslo.

Today's 4G network is becoming popular all over the world. However, their implementation is a challenging task. One of them is the fact that the high-frequency radio waves used in these networks, it does not penetrate through the urban structure. Therefore, (as compared with the 3G) requires more base stations to provide excellent coverage.
