4G Technology

Soon everyone will have high speed internet on their cell phones. This will enable instant access to e-mail and will allow fast, high quality video downloads. Moreover, all of these features will be attainable at a cheaper cost than current internet service. Currently 2G Technology (GSM), or second generation technology, is widely used worldwide for cell phone networks. The problem with 2G technology is that the data rates are limited. This makes it inefficient for data transfer applications such as video conferencing, music or video downloads. To increase the speed, various new technologies have been in development. One of these, 4G technology, is mainly made up of high-speed wireless networks designed to carry data, rather than voice or a mixture of the two. 4G transfer’s data to and from mobile devices at broadband speeds ? up to100 Mbps moving and 1Gbps while the phone is stationary. In addition to high speeds, the technology is more robust against interference and tapping guaranteeing higher security. This innovative technology functions with the aid of VoIP, IPv6, and Orthogonal frequency division multiplexing (OFDM).
