Abstract
A system and method of converting a cellular protocol of wireless communications at a vehicle includes receiving, at a relay device located in a vehicle, wireless communications that are sent from a vehicle telematics unit using a first cellular protocol; converting the wireless communications to a second cellular protocol at the relay device; and transmitting the converted wireless communications from the relay device to a cell tower using the second cellular protocol.

A method of converting a cellular protocol of wireless communications at a vehicle, comprising the steps of:
- (a) receiving, at a relay device located in a vehicle, wireless communications that are sent from a vehicle telematics unit using a first cellular protocol;
- (b) converting the wireless communications to a second cellular protocol at the relay device;
- and
- (c) transmitting the converted wireless communications from the relay device to a cell tower using the second cellular protocol.
A method of converting a cellular protocol of wireless communications at a vehicle, comprising the steps of:

- (b) converting the wireless communications to a second cellular protocol at the relay device;
- and
- (c) transmitting the converted wireless communications to a vehicle telematics unit using the second cellular protocol.
A relay device for converting a cellular protocol of wireless communications at a vehicle, comprising:
- a base station transceiver operating according to a first cellular protocol that communicates signals with a vehicle telematics unit;
- a control unit having a microprocessor and a memory device that translate output from the base station transceiver in the first cellular protocol into a second cellular protocol;
- and
- a cellular transceiver operating according to the second cellular protocol that receives the output from the control unit and wirelessly communicates it with a cell tower according to the second cellular protocol.
