Claim 8:
9. A wireless access point, comprising:
at least one radio operable to simultaneously transmit one or more subcarriers of a channel and receive one or more subcarriers of the channel;
a processor; and
a memory communicatively coupled with the processor and storing machine readable instructions that, when executed by the processor, control the processor to:
control the at least one radio to implement access to a conventional non-ad-hoc network over a wireless channel using a first number of subcarriers of the wireless channel;
control the at least one radio to implement an ad-hoc wireless network using an emergency channel having a plurality of emergency subcarrier groups, each of the emergency subcarrier groups having a second number, less than the first number, of subcarriers;
