December, standard of fixing radio communication. In addition, the working group of the IEEE 802 commission which deliberated the same standard.100 - To use the band of 66GHz, radius approximately 50km (30 miles) cover with 1 antenna, being maximum, the communication of 70Mbps is possible. However, it can communicate in only the range where the way is clear.Presently the telephone line and the terminal part of the member type communication network which the optical fiber has borne (generally known "rust onemile ") with you suppose that it utilizes unlike the wireless LAN which supposesthat you usein communication inside the building. The member type access netbyIEEE 802.16 "Wireless MAN" (radio MAN: Wireless Metropolitan Area Network) with you say. Attention is attracted as the expedient which offers broad band connection service cheaply even at the area whose population density is low. ... The continuation is readIEEE 802.16a of the additional specification which uses the band 2 - 11GHz is approved in2003January,is calledwith the term of endearment of WiMAX.
