摘要:
Medium-range and global network information and control for a vehicle is achieved with a portable wireless key fob, a user-provided nomadic device, and a vehicle-installed telematics unit including a medium-range RF transceiver and a wireless network transceiver. The fob includes a medium-range RF transceiver for bi-directional communication with the telematics unit, and a short-range wireless transceiver for bi-directional communication with the nomadic device. The fob communicates with the telematics unit in a conventional manner, and also relays information between the telematics unit and the nomadic device. If a communication initiated via the fob cannot be completed because the fob is out of range, the communication is sent to the nomadic device for network transmission to the telematics unit. If a communication initiated via the nomadic device cannot be completed due to inadequate signal reception, the communication is sent to the fob for RF transmission to the telematics unit.
