First Claim
1. A wireless local area network (WLAN) comprising:
- at least one access point radio; and
a plurality of nodes in wireless communication with the at least one access point radio according to media access control (MAC) parameters, each of the plurality of nodes having a quality of service (QoS) threshold for wireless communication with the at least one access point radio that is a function of the MAC parameters;
wherein each of the plurality of nodes comprises a controller configured to provide individualized control of the MAC parameters corresponding to the node, the controller programmed to;
measure current settings for at least a portion of the MAC parameters for the node;
input the current settings for the at least a portion of the MAC parameters of the node into a WLAN system model to generate a system model output; and
adapt a setting of at least one of the MAC parameters for the node to meet the QoS threshold for the node based on the system model output.

Abstract
A system for setting WLAN node operating parameters includes at least one access point (AP) radio and a plurality of nodes in wireless communication with the AP radio according to media access control (MAC) parameters. Each of the plurality of nodes has a quality of service (QoS) threshold for wireless communication with the AP radio that is a function of the MAC parameters and includes a controller configured to provide individualized control of the MAC parameters. The controller is programmed to measure current settings for at least a portion of the MAC parameters for the node, input the current settings for those MAC parameters of the node into a WLAN system model to generate a system model output, and adapt a setting of at least one of the MAC parameters for the node to meet the QoS threshold for the node based on the system model output.
