METHODS AND SYSTEMS FOR IMPROVED UTILIZATION OF A WIRELESS MEDIUM

摘要

Systems, methods, and devices for wireless communication are provided. In an embodiment, a method of determining communication parameters for wireless communication includes receiving, at an access point, a probe request comprising a transmission power indication. The method further includes determining a received transmission power. The method further includes estimating a path-loss based on the transmission power indication and received transmission power. The method further includes transmitting a first probe response using a first set of communication parameters defining a first rate. The method further includes transmitting a second probe response using a second set of communication parameters defining a second rate when the access point does not receive an acknowledgement to the first probe response within a timeout period, the second rate being lower than the first rate.

1. In a communication system including at least an access point and a plurality of wireless devices transmitting respective probe requests to the access point for determining whether the access point is within a range for initiating and maintaining a wireless communication link between each of the plurality of wireless devices and the access point, and the access point transmitting a probe response frame including communication parameters, a method for more efficient probe communication, comprising:
receiving, at an access point, a probe request comprising a transmission power indication; determining a received transmission power of the probe request; estimating a path-loss based on the transmission power indication and received transmission power; transmitting a first probe response based on a first set of communication parameters defining a first data rate; and transmitting a second probe response based on a second set of communication parameters when the access point does not receive an acknowledgement to the first probe response within a timeout period, the second set of communication parameters defining a second data rate lower than the first data rate.
