Abstract
A distributed data system utilizing a paging location system includes a plurality of local area networks (LAN) (38) that have a wireless data link associated therewith for accessing one of a plurality of personal data units (PDU) (10). Data transfer can be affected over a wireless link between antennas (18) and (44) by determining from an internal lookup table in each of the LANs (38) which of the LANs (38) is the homebase LAN (38). The data is then transferred to the homebase LAN (38) and the homebase LAN (38) then attempts to transfer the data to the destination PDU (10). If not located at that LAN (38), a paging message is then transferred through a paging system to all of the PDUs (10) and the destination PDU (10) then transmits a Ready-to-Receive message to the one of the LANs (38) that it is closest to. This is the receiving LAN (38) which then requests data to be transferred thereto from the homebase LAN (38) and then affects a transfer to the destination PDU (10).
