Abstract

A portable communication network comprises plural portable communications units, each providing a unit code identifier, a wave energy transceiver, preferably using RF energy which is enabled for direct communication with any other of the communications units over a limited range, a device for assigning a target code to each signal transmission, a device for detecting the target code in each signal reception, a device for processing a received signal when the target code of the received signal equals the unit code, and a device for retransmitting a received signal when the target code of the received signal differs from the unit code. In this manner, through signal repeating, communication is enabled between any two of the communications units when their separation is greater then the limited range. Automatic routing through the communication network is established between two members of the network. Alternate routes are established as background tasks to be switched in if the current route is interrupted.

Claims

1. A portable communication network comprising:

plural portable communications units, each providing;

(a) a unit code, (b) a wave energy transceiver enabled for direct communication with any other one of the communications units over a limited range, (c) means for assigning a target code to each signal transmission, (d) means for detecting the target code in each signal reception, (e) means for processing a received signal when the target code of the received signal equals the unit code, and (f) means for retransmitting a received signal when the target code of the received signal differs from the unit code;

wherein each one of the units is enabled for measuring a time delay between an interrogation and a reply with another of the units and for sending position information of said one of the units within a reply message, the one of the units enabled further for determining a relative position on the Earth of the one of the units by a triangulation method;

whereby, through signal repeating, communication is enabled between any two of the communications units when their separation is greater then the limited range.

2. The portable communication network of claim 1 wherein each of the units further comprises means for assigning route codes to each of the retransmitted received signals.

3. The portable communication network of claim 1 wherein each of the units further comprises means for assigning the unit code to each signal transmission.

4. The network of claim 2 wherein each of the units is further enabled for assigning a selected route code to a transmission subsequent to a previous transmission having the selected route code.

5. The network of claim 1 wherein at least one of the units is further enabled for fixed-wire communication.
