Abstract
A monitoring system comprises a specific remote unit or monitor and a plurality of base stations that are capable of communicating with one another. A designated one of the plurality of base stations transmits a message via a wireless medium to the specific remote unit on behalf of the plurality of base stations, and the plurality of base stations use a shared base station identifier or shared sender address for communication with the specific remote unit or monitor. In another aspect, a first designated one transmits a message during a first time period and a second designated one transmits a message during a second time period. Receiving messages from a designated one of the plurality of base stations using the shared base station identifier helps the specific remote unit or monitor to reduce its power usage.
