1. Ad-hoc wireless network method for failure reporting and emergency communication of a conventional non-ad-hoc network, comprising:
controlling a wireless access point to implement access to the conventional non-ad-hoc network over a wireless channel using a first number of subcarriers of the wireless channel;
controlling the wireless access point 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, wherein the wireless access point concentrates transmitter power into a smaller group of subcarriers with a first transmission range greater than a second transmission range of the conventional non-ad-hoc network; and
performing the failure reporting and the emergency communication over the emergency channel.
