Abstract:
An open loop method of transmission power control for use in a data communications network comprising a central control node and at least one remote subscriber node, said method comprising the steps of:a) transmitting a first signal from the central control node to the remote subscriber node; b) measuring a received power level of the first signal received at the remote subscriber node; and c) setting a transmit power level of the remote subscriber node in response to the received power level; wherein the setting step c), further comprises the steps of: i) using the received power level as an index into the look-up table of transmit power attenuator values; ii) selecting the indexed attenuation value; and iii) attenuating the transmit power level by the selected attenuation value; and wherein the transmit power level of the remote subscriber node is set before the remote subscriber node has transmitted any signals onto the network.
