Claim:
1. A wireless OFDM (Orthogonal Frequency Division Multiplexing) transceiver operable to: receive, in a first narrower frequency band, by a receiver using wireless OFDM communications, a first packet comprising a first number of OFDM symbols that carry a first plurality of header bits; demodulate, by a demodulator connected to and in communication with the receiver, the first number of OFDM symbols to determine the first plurality of header bits, 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; receive, in a second wider frequency band, by the receiver using wireless OFDM communications, a second packet comprising a second number of OFDM symbols, less than the first number of OFDM symbols, that carry a second plurality of header bits, different than the first plurality of header bits; and demodulate, by the demodulator, the second number of OFDM symbols to determine the second plurality of header bits, wherein the first narrower and second wider frequency bands have one or more overlapping frequency regions.
