Abstract
A communication system includes a hub, a repeater, and a remote. The hub is configured to adjust a transmission power of the remote depending on an external condition based on (i) a measured carrier-to-noise ratio CNHubsignal1 of data transmitted from the hub to the repeater and back to the hub using a first signal, (ii) a measured carrier-to-noise ratio CNHubsignal2 of data transmitted from the remote to the hub via the repeater using a second signal, (iii) a predetermined carrier-to-noise ratio CNHubSCPCCS of data transmitted from the hub to the repeater and back to the hub using the first signal under a clear sky condition, and (iv) a predetermined carrier-to-noise ratio CNHubTDMACS of data transmitted from a reference remote to the repeater and back to the hub using the second signal under a clear sky condition.
