ABSTRACT:
A remote coverage system extends the effective coverage area of a cellular mobile radiotelecommunications (CMR) master cell. When a mobile unit assigned to the master cell moves from the master cell's coverage area into the coverage area of a satellite cell, the satellite cell sends a signal asking for a handoff of the mobile unit to it. When the handoff occurs, the MTSO exchanges signals with the mobile unit via a relay unit located at the master cell site. The relay unit relays signals between the MTSO and the satellite cell.
