1. A method of allowing member nodes of a wireless point-to-multipoint (PMP) network to participate in mobile ad hoc (MANET) or mesh communications with other nodes on a shared set of channels without interfering with network communications conducted under a PMP protocol, comprising:

  • transmitting a downlink signal from a base station node to a number of subscriber station nodes in a wireless PMP network;

    defining a downlink map in the downlink signal for scheduling first time periods for transmitting messages from the base station node to corresponding ones of the subscriber station nodes, and defining an uplink map in the downlink signal for scheduling second time periods for allowing a subscriber station node to transmit messages to the base station node in a scheduled second time period; and

    allocating a MANET/mesh zone in either one or both of the downlink and the uplink maps, each zone operating to reserve one or more time slots and channels in which the base and any of the subscriber station nodes can communicate with other nodes using a MANET or mesh protocol while avoiding interference with network communications between the base and the subscriber station nodes under the PMP protocol.
