Abstract

A method and system that enables an automatic delay setting within a wireless local loop system. The present invention determines the transmission distance time delay existing between a base station and a personal station by employing the communication interface that is utilized between them. The main reason for determining the transmission time delay caused by large transmission distances (e.g., over 300 meters) existing between base stations and personal stations is to compensate for it. Once the transmission distance time delay is known, the personal station utilizes that value to compensate for it. Specifically, the present invention directs a base station to transmit a control signal to a personal station. The personal station receives the control signal and transmits a signal to the base station. The base station determines if it started to receive the signal from the personal station later than it expected the signal to arrive, assuming close proximity of the two stations. If the signal arrived when it was expected to arrive, the base station discontinues determining the transmission distance time delay. If the signal arrived later than expected, the base station calculates the time difference between the expected arrival time and the actual arrival of the signal. The time difference is equivalent to the transmission distance time delay. Once the time difference is determined, the base station then transmits it to the personal station. The personal station stores the transmission distance time delay value enabling it to compensate for it.
