However, many vendors are selling “11n draft” routers now in order to gain a better marketing position in the future. At the time of writing this chapter, IEEE802.11n is still in a draft form. It provides higher speed (up to 300 Mbps) and better security. The next generation of IEEE802 is 11n which still uses the 2.4 GHz radio band. The first products under this standard became available in January 2003. Organizations do not need to replace all existing 802.11b devices when they add new 802.11g technologies. IEEE802.11g provides a higher speed (up to 54 Mbps) and it is backward compatible to 802.11b. However, there are still a large number of 11b devices in use today. As the standard is slower than 11a and 11g, 11b products have been phasing out of the market in recent years. Installation is easy and there is widespread use in small offices and homes. Devices from different vendors are extremely compatible with each other. Access points and network cards using this standard are inexpensive. Under this standard, the data transfer rate is improved to 11 Mbps and the range to 100 m while still using the 2.4 GHz radio band. Although there are large numbers of new standards, only four standards have products in the market now. They differentiate these newer standards by appending a letter behind the 802.11. To overcome the shortcomings of the first design, IEEE workgroups have developed new IEEE802.11 standards. However, there are some well-known security weaknesses in this standard and the maximum speed is only 2 Mbps. It also defines the optional use of encryption. The standard specifies the communication between wireless client and the access points. This is one of the reasons that this standard has become so popular. Users do not need a license to use this band in most countries. It uses the 2.4 GHz radio band for communication. The first design began in 1990 and it took 7 years to be completed. IEEE (often pronounced as eye-triple-E) has developed many different communications standards to make sure devices from different vendors can communicate with each other. These standards were developed by the IEEE (Institute of Electronic and Electrical Engineers) which is a nonprofit making organization.

Wireless routers use the IEEE802.11 standards to communicate with user's computers.
