Aviation cellular communications system and method |
摘要 |
Disclosed are a system and method for controlling transmit power of a mobile node in air-to-ground communications to a fixed node. Power is controlled by taking into consideration the position of the mobile node, the ground position of a plurality of fixed nodes, and the RF pattern of an antenna. Preferably, a power level is selected that will excite the fewest number of the plurality of fixed nodes while still maintaining a stable connection with at least one of the fixed nodes. The system may also utilize a repeater to receive communication signals from one or more mobile phones. This repeater then pre-amplifies the signal with a gain control signal received from one of the plurality of fixed nodes. The repeater would then pass the pre-amplified signal to the power amplifier for further amplification as controlled by the power controller. |
