Patent ID: 7440411

Claim:
A method for determining transmission characteristics over a first communication path (PATH 1 ) and a second communication path (PATH 2 ), said first communication path originating from a first transceiver unit (TU 1 ) and terminating in a second transceiver unit (TU 2 ), said second communication path originating from said second transceiver unit and terminating in said first transceiver unit, said method comprising the steps of: determining in said second transceiver unit a first data rate (B 1 ) achievable over said first communication path while a first signal (NEAR) is being applied to said first communication path with a first initial transmit power (P 1 ), sending said first data rate to said first transceiver unit, determining in said first transceiver unit a second data rate (B 2 ) achievable over said second communication path while a second signal is being applied to said second communication path with a second initial transmit power (P 2 ), and while an amount of said first signal is coupling into said second communication path (ECHO), characterized in that, in the event of said first data rate being higher than a first target data rate (BT 1 ) and said second data rate being lower than a second target data rate (BT 2 ), said method further comprises the step of determining an optimal transmit power (P 1 ′) over said first communication path lower than said first initial transmit power such that capacity of said second communication path is increased beyond said second target data rate while capacity of said first communication path is kept higher than or equal to said first target data rate.
