1. A method of assessing communication quality in a wireless network comprising a plurality of access points, said method comprising:

  • receiving as input path loss information indicating path losses between a selected client of said wireless network and said access points;

    based on said path loss information, determining a capacity indicator that estimates communication impairment for said client due to contention or collision;

    based on said path loss information, determining a data rate indicator that estimates an achievable data rate for communication by said selected client;

    determining a cell loading indicator that estimates communication impairment due to overloading of a cell occupied by said selected client, said cell loading indicator based on an estimated number of clients in communication with said access points; and

    based on said capacity indicator, said data rate indicator, and said cell loading indicator, determining a client throughput;

    wherein determining said client throughput comprises multiplying said capacity indicator by said data rate indicator and said cell loading indicator.
