ABSTRACT – “The early development and impact of 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 transfers 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).
