Frequency hopping in 5GHz WLAN via dynamic frequency selection
First Claim
1. A method for dynamically selecting a communication channel between an access point (AP) and at least one mobile terminal (MT) located within the coverage area of a cell in a wireless local area network (WLAN), the method comprising:
- measuring a channel quality of a plurality of frequency channels, including a received signal strength indicator (RSSI) for each channel measured;
updating a list of best available frequency channels based on the RSSI of each channel;
upon expiration of a timer, selecting one of the channels from the list of best available frequency channels, other than a currently used channel, for use in communication between the AP and the at least one mobile terminal; and
switching to the selected channel.

Abstract
Disclosed is a method and system for dynamically selecting a communication channel between an access point (AP) and a plurality of mobile terminals (MTs) in a wireless local area network (WLAN), the method having the steps of (a) measuring a channel quality of a plurality of frequency channels, (b) reporting to the AP from the plurality of MTs of the candidate channels including a received signal strength indication (RSSI) of all channels measured and, (c) selecting one of the channels based on the channel quality report for use in communication between the AP and the plurality of MTs.
