Wireless Fidelity

Paper Summary:

This paper describes the flaws and advantages of current standards for wireless Internet technology and looks at some of the technology available and under development that address some of those problems. The paper also discusses the advantages and disadvantages of wireless Internet access from both the social and the legal points of view. An outline of the paper is included at the beginning.

From the Paper:

"802.11g is the current standard technology for wireless networking. 802.11g is nominally capable of 54 Mb/s connections, just over half the speed of typical wired Ethernet. In reality, speeds are usually much lower. A typical fast Internet connection is less than 6 Mb/s, so 802.11g is more than adequate for Internet access. 802.11g is limiting in situations involving transfer of large files between computers on the same network and use of high-bandwidth applications. 802.11g can also be problematic in an area with a high concentration of wireless networks. The range of frequencies that 802.11g is able to use is very narrow. An apartment complex in a technologically sophisticated area may have a number of overlapping networks, resulting in interference. 802.11n will have a larger frequency range in which to operate, as well as larger channels and faster hardware technologies such as MIMO, or multiple in, multiple out. MIMO technology involves using multiple antennas to maintain several parallel connections between a wireless access point and a computer's wireless network card. MIMO increases the overall bandwidth available to the network."
