MEDIUM RANGE VEHICLE COMMUNICATION SYSTEM

摘要

A communication system for communicating with a vehicle via a wireless personal communication device such as a smart phone. The communication system uses medium-range transceivers to extend the effective range of the communication system. A communication device accessory that includes a portable medium-range RF transceiver is coupled to the wireless personal communication device so that power for the portable medium-range RF transceiver can be drawn from the wireless personal communication device. The communication device accessory is electrically coupled to the wireless personal communication device via a wired connection that provides at least a wired electrical power connection and optionally a wired data connection between the communication device accessory and the wireless personal communication device.
