US 2025/0062837 A1 · POWER COMPENSATION DETERMINATION FOR RADIO FREQUENCY CABLE

Abstract

In implementations of the present disclosure, a power compensation determination for radio frequency cable mechanism is provided. An access point (AP) determines a time slot for an RF cable loss measurement on an RF cable, and transmits a test signal with a first TX power to an antenna module over the RF cable. The AP further obtains a second TX power transmitted by the antenna module, and determines an RF cable loss based on the first TX power and the second TX power. The AP further determines power compensation for the RF cable based on the determined RF cable loss, the first TX power and an antenna gain of the antenna module. The AP transmits signals on the RF cable to the antenna module based on the determined power compensation. Implementations of the present disclosure can determine the power compensation based on the RF cable loss automatically.
