1. A communication system for efficiently transmitting information signals that were formatted in variable sized packets of more than a minimum size by using time division transmission of packet segments and allocating available bandwidth on demand, said system comprising:

  • a satellite/wireless network;

    at least two sites, each comprising a plurality of terminals operative to transmit and receive signals via said satellite/wireless network and a local area network for interconnecting said terminals at a common site, each said terminals comprising;

    (a) a modem for transmitting signals from a terminal on predetermined channels having a predetermined bandwidth;

    (b) means for time dividing data signals input to said terminal from an external location and for assembling said time divided data signals as bursts within repeated frames, each frame having a unique frame header;

    (c) means for dividing information signals arranged in variable sized packets into a plurality of segments;

    (d) means for combining each segment in said plurality of segments with a unique segment and reassembly header to form a SAR segment;

    (e) means for combining said SAR segments representing a single packet with a unique frame header to form a SAR frame; and

    (f) means for selectively appending a terminal ID header to each said SAR frame for transmission in a burst from a modem.
