Aircraft communications are established on a cellular system by having the transmission to aircraft directed above ground level so as not to interfere with ground cellular systems and having the transmissions from the aircraft at extreme low power levels so as not to interfere with transmissions from ground vehicles. The location of mobile stations either aircraft or ground vehicles for one embodiment is determined by Loran reception or other radio navigation system in the mobile station and transmitted to a mobile switching center to be used in transferring control from cell to cell by use of the determined location of the mobile station. For another embodiment the antennae for aircraft (both base station and mobile) are horizontally oriented while ground vehicle antennae (both base station and mobile) are vertical as in present commercial practice.
