DATATrak News - March 2002

29 March 2002 - IEEE802.11b 2.4GHz WLAN - OFDM Modulation, etc.

ARIB, the Association of Radio Industries and Businesses should be releasing soon (April 2002) a revised version of the STD-T66 standard, which includes the requirements for OFDM modulation. The use of the OFDM modulation should make data speeds as high as 22Mbps. The revised version of the standard will cover channels 1 to 13. Regarding the 14th channel, the current version of the ARIB STD-33 will apply. (And the very strict issue on the spreading ratio remains...)
