4g Wireless Networks Essay
4G Wireless Networks
This paper will compare and contrast 3G wireless networks to 4G networks in terms of services and application, network architecture, data throughput and user perceptions, it will distinguish between the 4G LTE, 4G WiMax, and 4G WiBro networks based on upload and download speeds, user perceptions, backward compatibility, service availability. It will also identify why the competition between the 4G LTE carriers has been so fierce and will describe the benefits of this competition to the subscribers.
In January 2012, Verizon stated that 4G LTE is available in 190 cities covering 200 million American subscribers. According to AT&T’s Website, they had plans for covering 20 million …show more content…
B. Compare and contrast 3G wireless networks to 4G networks in terms of network architecture
One of the differences between these two standards of networks lies in the network architecture; the 3G mobile network is a Wide Area Cell Based network with a circuit-switched subsystem. It relies on large satellite connections that connect to telecommunication towers. For example, users make a call or open the internet; a radio signal is transmitted to a 3G tower antenna or cell site. That data travels from the cell site to a central switching office by a wire-line fiber-optic network. Then the central switching office connects the call or data request with the rest of the world. The 4G networks are an integration of wireless LAN and Wide Area. 4G does not have a
