A system and method are provided for monitoring and recording the movements of a plurality of mobile units in an environment in which more than one type of mobile unit is present. For inventory control, an emitter tag is mounted on each mobile unit. Initially, the mobile units are physically sorted by type and each emitter is read to input each mobile unit's unique tag identifier and the corresponding mobile unit type (setup data) into computer readable memory at a base station. For the system, a plurality of remote stations, each having a limited signal receiving range, are strategically positioned in the environment. Each remote station receives in-range emitter signals and communicates the occurrence of mobile unit movements (operational data) to the base station. The operational data can be used together with the setup data described above to generate mobile unit movement reports for each mobile unit type. |
