1. A method in a ground-based communication station for power control of a digital datalink system within an aeronautical telecommunication network, comprising:
- determining a channel spatial capacity requirement of the ground-based communication station, wherein a channel spatial capacity requirement is determined based on a ratio between a channel capacity of the ground-based communication station and a coverage area zone of the ground-based communication station;
determining a transmission power of the ground-based communication station based on the spatial capacity requirement such that the channel spatial capacity of the ground-based communication station is increased and inversely proportional to the transmission power and the coverage area zone of the ground-based communication station;
issuing information representing the determined transmission power to one or more air-based communication stations within the coverage area zone of the ground-based communication station, wherein a transmission power of each of the air-based communication stations is calculated and set to a decibel level higher than or equal to the transmission power of the ground-based communication station; and
receiving data from each of the air-based communication stations.
