Current Numbering System for 802.11
Dec. 2009 Current Numbering System for Channel center frequency = Channel starting frequency + 5 × nch (MHz) (17-27) Where nch = 1,…200 Channel starting frequency =dot11ChannelStartingFactor × 500 kHz For example, dot11ChannelStartingFactor = indicates that Channel zero center frequency is GHz. The value NULL for nch shall be reserved. This system is generated for bandwidths of 5,10 and 20 MHz, where the difference between two center frequency is always a multiple of 5 MHz.

Dec. 2009 5 MHz Channels We are suggesting to use center frequencies of available bands for 5 MHz channels. This will reduce adjacent channel problems. In USA/CANADA, we need to have 5 starting frequencies. We selected 50 MHz, 51 MHz, 52 MHz , 53 MHz, 54MHz with dot11ChannelStartingFactors of 100, 102, 104,106,108 respectively. Tuncer Baykas, NICT

Dec. 2009 10 MHz Channels We are suggesting to use middle frequency of available adjacent bands. In USA/CANADA, we need to have 5 starting frequencies. We selected 50 MHz, 51 MHz, 52 MHz , 53 MHz, 54MHz with dot11ChannelStartingFactors of 100, 102, 104,106,108 respectively. Tuncer Baykas, NICT
