Method for evaluating the quality of a radio transmission channel and a residential gateway using the method

摘要

A method for assessing quality of a transmission channel in a wireless network comprises the steps of a) a first station (1) transmitting a first unicast message (RESPONSE 1) to a second station (2a) by said transmission channel; b) if no acknowledgement (ACK) of the first unicast message (RESPONSE 1) is received from the second station (2a), the first station (1) transmitting a further unicast message (RESPONSE 2,RESPONSE 3, ...) at a higher power level, and c) if an acknowledgment (ACK) of the first or any further unicast message (RESPONSE 1, RESPONSE 2,RESPONSE 3, ...) is received from the second station (2a), assessing the quality of the transmission channel based on the power level or the number of transmissions that were needed to trigger the acknowledgment (ACK).
