DETERMINING THE RELIABILITY OF COMMUNICATIONS BETWEEN A PORTABLE ELECTRONIC DEVICE AND AN ACCESS POINT

摘要

A method and system are described for determining the reliability of the communications between a portable electronic device and an access point (AP) before associating with the AP. In the described embodiments, a first probe request frame is transmitted to the AP at a first data rate, and a first probe response frame is received from the AP, wherein the first probe response frame is responsive to the first probe request frame. Then, a second probe request frame is transmitted to the AP at a second data rate, wherein the first data rate is lower than the second data rate. Then, the portable electronic device determines if a second probe response frame is received from the AP, wherein the second probe response frame is responsive to the second probe request frame. The portable electronic device then determines the reliability of the communications between the portable electronic device and the AP.

1. A method for determining a reliability of communications between a portable electronic device and an access point (AP), the method comprising:
the portable electronic device transmitting a first probe request frame to the AP at a first data rate; the portable electronic device receiving a first probe response frame from the AP, wherein the first probe response frame is responsive to the first probe request frame; the portable electronic device transmitting a second probe request frame to the AP at a second data rate, wherein the first data rate is lower than the second data rate; the portable electronic device determining if a second probe response frame is received from the AP, wherein the second probe response frame is responsive to the second probe request frame; and the portable electronic device determining the reliability of the communications based on whether or not the second probe response frame is received from the AP.
