doc.: IEEE 802.11-10/0xxxr0 Submission Current Numbering System for 802.11 Channel center frequency = Channel starting frequency + 5 × nch (MHz) Where nch = 1,…200 Channel starting frequency =dot11ChannelStartingFactor × 500 kHz For example, dot11ChannelStartingFactor = 10000 indicates that Channel zero center frequency is 5.000 GHz. The value NULL for nch shall be reserved.. Sep 2010 Tuncer Baykas, NICTSlide 3

doc.: IEEE 802.11-10/0xxxr0 Submission Proposed Numbering System for 802.11 Channel center frequencies are defined at every integral multiple of Channel number multiplier 5 MHz above Channel starting frequency. The relationship between center frequency and channel number is given by Channel center frequency = Channel starting frequency + Channel number multiplier × nch(MHz) where nch = 0, 1,…200.

Minimum TV channel occupancy. 5 MHz channel center frequencies match center frequencies of TV Channels. 10 MHz channel center frequencies are at the lower end of TV Channels.

Each 40 MHz channel has an upper and lower 20 MHz channels. Each 20 MHz channel has an upper and lower 10 MHz channels. 520 MHz600 MHz640MHz 560 MHz680MHz480 MHz 470 MHz698MHz Ch. 36-38
