A method for evaluating the performance of a wireless LAN (local area network) system having a single access point and a plurality of transmission terminals, which share the same radio channel, comprises the steps of dividing the plurality of transmission terminals into groups in accordance with radio conditions, calculating a transmission probability and a post-transmission failure probability for each group using a transmission rate, an error rate, and the number of terminals of each group, and calculating a throughput based on the transmission probability and post-transmission failure probability. A characteristic value for packet transmission delay may also be calculated based on the transmission probability and post-transmission failure probability. According to this method, the performance such as the throughput and the packet transmission delay can be evaluated in a wireless LAN system even before the wireless LAN system is constructed.
