Abstract:
1. A mobile telecommunication device for use on an aircraft, comprising: at least first and second antennas configured to communicate with one or more base station, wherein the first and second antennas are configured to be positioned on the aircraft with the second antenna located more to a front part of the aircraft than the first antenna, and an electromagnetic shield located between the first and second antennas, the electromagnetic shield having a first side facing the first antenna and a second side facing the second antenna, a logic component configured to be operationally coupled to the first and second antennas in conjunction with use of the mobile telecommunication device on the aircraft; wherein the electromagnetic shield is configured to reflect electromagnetic radiation impinging on the first side such that at least a portion of the radiation impinging thereon is reflected towards the first antenna so that, in conjunction with use of the mobile telecommunication device on the aircraft, the first antenna has higher antenna gain than the second antenna in a rear direction of the aircraft, wherein the electromagnetic shield is configured to reflect electromagnetic radiation impinging on the second side such that at least a portion of the radiation impinging thereon is reflected towards the second antenna so that, in conjunction with use of the mobile telecommunication device on the aircraft, the second antenna has higher antenna gain than the first antenna in a forward direction of the aircraft, wherein the electromagnetic shield is configured to at least partially shield the second antenna from receiving radio signals transmitted by the first antenna and to at least partially shield the first antenna from receiving radio signals transmitted by the second antenna; wherein, in conjunction with use of the mobile telecommunication device on the aircraft, the logic component is configured to select whether the first antenna or the second antenna is used for transmissions via a reverse link of a telecommunication connection with a base station located on the ground based at least in part on information indicative of improved reverse link communications via the selected antenna.
