Abstract:
1. A wireless radio frequency (“RF”) modem constructed to cooperatively operate with an external message split controller, said external message split controller operative to split a message into a plurality of message fragments according to one or more predetermined criteria, and to include with each said message fragment an identifier of where said fragment was located within said message, to enable each said message fragment to be transmitted to said RF modem as a separate electromagnetic signal via a separate selected transmitting source over a corresponding selected radio frequency, said RF modem comprising: an RF front end operative, for each said separate electromagnetic signal, to receive the signal, to detect the radio frequency over which the signal was transmitted and to downconvert the signal to generate a corresponding baseband signal; a baseband processing unit coupled to said RF front end and operative to detect and decode each said baseband signal generated by said RF front end to generate each said corresponding transmitted message fragment; a central processing unit (“CPU”) coupled to said RF front end and to said baseband processing unit, said CPU operative to detect said identifiers; and a message fragment combining unit coupled to said CPU for combining said message fragments as a function of said identifiers to generate the original message.
