Claim:
1. A wireless OFDM (Orthogonal Frequency Division Multiplexing) transceiver comprising: a modulator operable to modulate a first number of OFDM symbols to transmit a first plurality of header bits in a first packet, wherein at least one header bit of the first plurality of header bits in the first packet is repeated on a plurality of OFDM subcarriers; a wireless OFDM communications transmitter, connected to and in communication with the modulator, operable to transmit in a first narrower frequency band, the first packet comprising the first number of OFDM symbols; the modulator further operable to modulate a second number of OFDM symbols to transmit a second plurality of header bits in a second packet, wherein the second number of OFDM symbols is less than the first number of OFDM symbols and wherein the second plurality of header bits is different than the first plurality of header bits; and the wireless OFDM communications transmitter further operable to transmit in a second wider frequency band, the second packet comprising the second number of OFDM symbols, wherein the first narrower and second wider frequency bands have one or more overlapping frequency regions.
