What are the different types of wireless network technologies?
Currently there are three options: 802.11b, 802.11a, 802.11g. The sections below compare these technologies. 802.11b Speed: Up to 11 megabits per second (Mbps) Pros • Costs the least • Has the best signal range Cons • Has the slowest transmission speed • Allows for fewer simultaneous users • Uses the 2.4 gigahertz (GHz) frequency (the same as many microwave ovens, cordless phones, and other appliances), which can cause interference 802.11a Speed: Up to 54 Mbps Pros • Has the fastest transmission speed • Allows for more simultaneous users • Uses the 5 GHz frequency, which limits interference from other devices Cons • Costs the most • Has a shorter signal range, which is more easily obstructed by walls and other obstacles • Is not compatible with 802.11b network adapters, routers, and access points 802.11g Speed: Up to 54 Mbps Pros • Has a transmission speed comparable to 802.11a under optimal conditions • Allows for more simultaneous users • Has the best signal range and is not easily o
