Abstract: A system (100) for connecting a plurality of mail systems (1-N) each transmitting information from one of a plurality of originating processors (A-N) to at least one of a plurality of destination processors (A-N) which may be transported during operation in accordance with the invention includes at least one interface switch (304), an interface switch being coupled to each of the plurality of electronic mail systems of receiving information originating from an originating processor in one of the electronic mail systems for transmission to a destination processor in another electronic mail system; and a RF information transmission network (302), coupled to the at least one interface switch, for transmitting stored information received from one of the at least one interface switch originating from an originating processor in one electronic mail system by RF transmission to at least one RF receiver which relays the information to a destination processor within the another electronic mail system.

Abstract: A system and method for transmission of information subject to fading by using a RF carrier modulated with a subcarrier modulated with the information. The system has a processor for providing first and second encoded information streams each comprising the information to be transmitted with the second stream being delayed by a time delay interval with respect to the first stream which is equal to or greater than the fading interval. The first and second information streams are modulated on cycles of the subcarrier to produce first and second parallel information streams. At least one receiver having a detector receives and detects the transmitted first and second parallel information streams. At least one processor determines if faded information is present in the detected first and second parallel information streams.

Abstract: A system for transmitting originated information from one of a plurality of originating processors in an electronic mail system to at least one of a plurality of destination processors in an electronic mail system in accordance with the invention includes a RF information transmission network for transmitting the originated information to at least one RF receiver which transfers the originated information to the at least one of the plurality of destination processors; at least one interface switch, the at least one interface switch being coupled to the electronic mail system containing the plurality of originating processors and the RF information transmission network and transmitting the originated information received from the electronic mail system containing the plurality of originating processors to the RF information transmission network; and at least one additional processor with each additional processor being coupled to at least one interface switch and transmitting other originated information to th
