NOTE 1:
Min Ranging TOS = 1 / (frame duration x 10), e.g. 1 / (10mS x 10) = 10
NOTE 2:
Initial Burst TTG = Bw x 392, e.g. 5(MHz) x 392 = 1960, 10(MHz) x 392 = 3920

NOTE 5:
Request Backoff Start =
Case 1: with No Subchannelised BW requests -
lookup index = OFDM Profile:Frame Duration x OFDM Profile: Min Req Region Full Tx Opps
Example: 0.010 x 100 = 1, using lookup table (see below), Request Backoff Start = 0
Case 2: using Subchannelised BW requests -
lookup index = OFDM Profile:Frame Duration x BS Custom: Min Subchannel Req Region Full Tx Opp
Example: 0.005 x 800 = 4, using lookup table (see below), Request Backoff Start = 2
