1. A method of configuring a wireless RF network, the network comprising a plurality of network nodes for communicating with other nodes, each node of the wireless RF network having a controller unit, a data store and a unique identifier, the method comprising the steps of:

  • a) selecting at least one of the plurality of nodes to serve as a control node of the wireless RF network;

    b) providing the at least one selected control node with a unique host ID stored in a host ID register accessible to said selected control node;

    c) periodically detecting other nodes within the coverage area of each respective node of the plurality of nodes by sending an inquiry message;

    d) periodically updating the data store of each respective node of the plurality of nodes with addresses of detected nodes received from responses to the inquiry message by said detected nodes;

    e) storing the unique identifier of each respective node prescribed to pertain to the wireless RF network accessible to the at least one control node of the wireless RF network;

    f) transmitting from the at least one control node of the wireless RF network a dynamic paging message addressed to each respective node located within the coverage area of the at least one control node according to step (d) and having the unique identifier stored accessible to the at least one control node according to step (e);

    g) updating the data store of each respective node receiving the dynamic paging message and returning relative information of the updated data store to the at least one control node of the wireless RF network from each respective node receiving the dynamic paging message;

    h) storing the received relative information of the updated data store accessible to the at least one control node of the wireless RF network;

    i) transmitting from the at least one control node of the wireless RF network a message to each respective node which returned the relative information of the updated data store, the message instructing said node to send the dynamic paging message addressed to each respective node matching predefined criteria;

    j) repeating steps (g) to (i) until every node identified to the at least one control node according to step (e) has been paged.
