4G Network Specifications

4G Network is although still under development, the basis for the upgrade from 3G to 4G service began in the 21 century, companies began to introduce new technologies. New standards such as WiMax and Long Term Evolution (LTE) was listed as 4G, but there is some debate about its status.
4G Specifications

Network for 4G are oriented to the high quality of service and speed of data transfer. The priorities of this standard has better reception with less data discarded, and faster exchange of information. The International Telecommunication Union (ITU), the body that oversees the standards for wireless networks, has stated that major improvements multimedia messaging services, including video services, requires the approval of a new generation.

4G required speed data transmission rates of at least 100 megabits per second, while a user is moving at high speed, such as in a train and one gigabit per second data in a fixed position. ITU also requires rapid transfer between networks without interruption or loss of signal. The phone also has a 4G network using the Internet Protocol (IP) for the transmission of data in transit, rather than a traditional phone.
Trend towards 4G

Several working groups have been established to contribute to the development of 4G networks. The initial development of this technology include WiMax, which is a faster version of data transfer in Wi-Fi ® networks. LTE is a new technology that improves over 3G, but it is not fully compatible with the requirements of the ITU standard for data transmission.

Both were branded as 4G networks, but led to some confusion and disagreement. Since both methods use IP packets, and showed significant improvement compared with the 3G standard, ITU 4G approved labeling. This is related to WiMax and LTE developers to advance to meet official standards for 4G, which has continued to do so.
Update 3G to 4G

The implementation of the 3G network in the world took almost a decade. The ITU expects 4G network was launched in the world market in a more efficient and timely. Improvements between 2G and 3G substantial improvements necessary hardware for mobile devices, while many companies have developed smart phones used for 3G networks to be compatible with the new 4G standard. However, concerns about the stability and security somewhat reduced development ", as service providers to ensure that they want to protect customer information.
4G network before the first

The first wireless networks, called 1G, was founded in 1980. 2G was introduced in the 1990s to allow multiple transmissions to occur communication. The basis of 3G technology was introduced in late 1990 and has been implemented in most of the world in the 21st century. Although the 3G network was the first to give multimedia applications, 4G promises to bring this technology base and expand significantly.
