A self-contained antenna module for attachment to a vehicle exterior, includes a connector for attaching to an existing wired feed connector to an entertainment head unit, a cellular communications module, e.g. a 3G/4G module configured to provide a local wireless internet access point, and a renewable energy source for generating independently of the vehicle's own power source electrical energy for charging an on-board battery which provides power to the cellular communications module. |
