Patent ID: 8780755

Claim:
An apparatus comprising: circuitry that generates a congestion quality metric based on a number of packet transmission retries and a received signal strength at a wireless client, wherein the circuitry generates the congestion quality metric further based on both a first rate at which the number of packet transmission retries is changing and a second rate at which the received signal strength is changing, wherein the first rate at which the number of packet transmission retries is changing is determined based on a difference between a current number of packet transmission retries and a previous number of packet transmission retries, and wherein the second rate at which the received signal strength is changing is determined based on a difference between a current received signal strength and a previous received signal strength; circuitry that receives configuration data generated by a querying system based on the congestion quality metric; and circuitry that configures one or more transmission parameters of the wireless client according to the configuration data.
