doc.: IEEE /0xxxr0 Submission Current Numbering System for Channel center frequency = Channel starting frequency + 5 × nch (MHz) 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.. Sep 2010 Tuncer Baykas, NICTSlide 3

doc.: IEEE /0xxxr0 Submission Proposed Numbering System for 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.
