RELAY DEVICE AND ASSOCIATED VEHICLE AND METHOD

摘要

It is presented a relay device arranged to act as a relay to provide relayed access for at least one wireless device within a vehicle to a cellular radio communication network. The relay device comprises: a relay node device comprising a vehicle antenna for communicating with the at least one wireless device; a first directional antenna directed in a first direction, the first directional antenna being connected to the relay node device; and a second antenna which is not directed in the first direction, the second antenna being connected to the relay node device. The first directional antenna and second antenna are arranged to communicate with fixed radio base stations of the cellular radio communication network; and the first direction is essentially parallel to a direction of travel of the vehicle. A corresponding vehicle and method are also presented.
