1. A node for use in a wireless multinode network, the node comprising:

  • a wireless transceiver arranged to transmit signals to and receive signals from other nodes in the network, with all nodes transmitting and receiving on a same frequency at any given time; and

    a processor coupled to the transceiver which is arranged to;

    detect a jammed status of the node;

    provide a jammed status report to be transmitted to at least one other node or base station in the multinode network; and

    process a received broadcast command, received from another node or base station in the multinode network, responsive to the jammed status report, to change the same frequency to a new same frequency for all nodes, after a fixed period of time, wherein the jammed status may be low, medium, or high and wherein the processor causes the transceiver to transmit the jammed status report when the jammed status is medium or low but delays transmission of the jammed status report when the jammed status is high.
