Abstract
A system (10) and method delivers simplex 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 retransmission apparatus (14, 16, 22) to receive (204, 304, 402, 404) the signals (26, 28) and retransmit (208, 310, 410) them within the area (20). Geolocation signals (26) from navigation satellites (12) can be retransmitted (208, 310) using the infrastructure retransmission apparatus (14, 16, 22), thus enabling a communication unit (24) located within an obstructed area (20) to calculate its position.
