More Information
Summary:An RF communication system contains a control module (22) which communicates with a plurality of user modules (20) that are each connected to at least one user device (24). The system provides a means for packet communications in which traditional destination addressed packets (34) are communicated to the specified destination point (24) or user module (20) while also permitting information (52) intended for a plurality of user modules (20) to be broadcast simultaneously to all user modules (20) using a broadcast protocoal (46). The probability of each UM (20) receiving the broadcast packet (46) is enhanced by the transmission by the control module (22) of each broadcast packet (46) over at least several of its directional antennas (A1-A6) and preferably repeated over each antenna (A1-A6) a number of times (R). Packets of data (34) which are longer than a predetermined number of bytes (L) are broken into packet fragments (46).
