ABSTRACT:
An electronic short range communication system which allows communication between two or more parties who are fairly close to each other and which allows communication between parties having the communication equipment without interfering with those who do not have communication equipment. The equipment has a definite range limit so as to prevent undesirable interference with other similar systems located beyond a reasonable distance. This system also permits communication from the nearest units of the system so as to override communication originating from more remote units.
