802.11 Standard 
802.11, or IEEE 802.11, is a type of radio technology used for wireless local area networks (WLANs). It is a 
standard that has been developed by the IEEE (Institute of Electrical and Electronic Engineers), 
 
http://standards.ieee.org. The IEEE is an international organization that develops standards for hundreds of 
electronic and electrical technologies. The organization uses a series of numbers, like the Dewey Decimal 
system in libraries, to differentiate between the various technology families. 
The 802 subgroup (of the IEEE) develops standards for local and wide area networks with the 802.11 section 
reviewing and creating standards for wireless local area networks. 
Wi-Fi , 802.11, is composed of several standards operating in different radio frequencies: 802.11b is a 
standard for wireless LANs operating in the 2.4 GHz spectrum with a bandwidth of 11 Mbps; 802.11a is a 
different standard for wireless LANs, and pertains to systems operating in the 5 GHz frequency range with a 
bandwidth of 54 Mbps. Another standard, 802.11g, is for WLANS operating in the 2.4 GHz frequency but 
with a bandwidth of 54 Mbps. 
802.11a Standard 
An IEEE specification for wireless networking that operates in the 5 GHz frequency range (5.15 GHz to 
5.85 GHz) with a maximum 54 Mbps data transfer rate. The 5 GHz frequency band is not as crowded as the 
2.4 GHz frequency, because the 802.11a specification offers more radio channels than the 802.11b. These 
additional channels can help avoid radio and microwave interference. 
802.11b Standard 
International standard for wireless networking that operates in the 2.4 GHz frequency range (2.4 GHz to 
2.4835 GHz) and provides a throughput of up to 11 Mbps. This is a very commonly used frequency. 
Microwave ovens, cordless phones, medical and scientific equipment, as well as Bluetooth devices, all work 
within the 2.4 GHz frequency band. 
802.11d Standard 
802.11d is an IEEE standard supplementary to the Media Access Control (MAC) layer in 802.11 to promote 
worldwide use of 802.11 WLANs. It will allow access points to communicate information on the 
permissible radio channels with acceptable power levels for client devices. The devices will automatically 
adjust based on geographic requirements. 
The purpose of 11d is to add features and restrictions to allow WLANs to operate within the rules of these 
countries. Equipment manufacturers do not want to produce a wide variety of country-specific products and 
users that travel do not want a bag full of country-specific WLAN PC cards. The outcome will be 
country-specific firmware solutions.
