Abstract
A system (10) and method delivers geolocation or other signals (26, 28) to a communication unit (24) located within an area (20) (e.g., a building) where an obstruction exists between the signal transmitter (12, 18) and the communication unit (24). The system (10) uses an infrastructure transceiver apparatus (14, 16, 22) to receive (204, 304, 604) the signals (26, 28) and retransmit (208, 310, 610) them within the area (20). A communication unit (24) calculates responsive data, such as its approximate position, from the retransmitted signals and reports (406, 704) the responsive data to a host system via the infrastructure transceiver apparatus (14, 16, 22).
