Method and system for providing adaptive probe requests
First Claim
1. A method of receiving RF signal quality information comprising the steps of:
- at a first station, receiving a plurality of probe responses over a channel;
determining a current transmit rate of the probe responses;
synchronizing signal processing to the current transmit rate of the probe responses; and
processing the probe responses to determine at least one of a signal quality of the channel and a transmission protocol being used over the channel;
wherein the probe responses are transmitted in reply to probe requests generated by a second station.

Abstract
A method of providing RF signal quality information which includes the step of a probe request generator (110) monitoring a channel for probe requests being transmitted by a station (115) and/or probe responses being transmitted by an access point (105). The probe request generator can determine a time period between the successive probe request transmissions received from the station or successive probe responses received from the AP. The probe request generator can generate a series of probe requests (150) having the determined time period between successive probe request transmissions. The series of probe requests signal an access point (105) to transmit probe responses (155) which are detectable by the station.

13. A device for generating probe requests comprising:
-
a probe request processor which receives probe requests generated by a station and determines a time period between successive probe requests that are received from the station;
a probe request timing database which stores time stamps associated with the probe requests; and
a probe request scheduler which schedules probe request transmissions at intervals correlating to the determined time period between the received probe requests;
wherein the probe request transmissions signal an access point to transmit probe responses which are detectable by the station. - View Dependent Claims (14, 15, 16)

17. A system for synchronizing a radio transceiver to a wireless local area network, comprising:
-
a first receiver for receiving a plurality of probe responses over a channel in response to at least one probe request;
a processor in the radio transceiver programmed to;
initiate a probe request if no probe responses are detected at the first receiver;
stop further probe requests if probe responses in response to probe requests from another device are received at the radio receiver; and
synchronize to at least one among probe requests from another device and probe responses in response to probe requests from another device. - View Dependent Claims (18)
