Claim:
1. A method of receiving wireless transmissions that each have a header and a payload, comprising: (a) demodulating a preamble of the header in accordance with a first modulation; (b) decoding a coded modulation indicator carried in the preamble; (c) demodulating the payload and a remainder of the header in accordance with a modulation indicated by the decoded modulation indicator; (d) selecting the coded modulation indicator from a plurality of coded modulation indicators respectively associated with a plurality of modulations available for transmission; (e) the plurality of modulations including the first modulation and a second modulation that is lower than the first modulation; (f) scheduling the wireless transmissions, in accordance with a modulation schedule for wireless transmission reception, to occur respectively in a first set of transmission intervals, including scheduling further wireless transmissions in accordance with the modulation schedule to occur respectively in a second set of transmission intervals that is disjoint from the first set, and including demodulating the headers and payloads of the further wireless transmissions in accordance with a third modulation that is different from the first and second modulations and is specified by the modulation schedule; (g) the third modulation is lower than the second modulation; and (h) the first and second sets of transmission intervals both occur during a periodic time cycle, and including dynamically updating the modulation schedule by adjusting respective sizes of the first and second sets of transmission intervals inversely relative to one another based on a total number of neighboring active wireless communication devices.
