A tool for providing a site survey of a wireless network. In one embodiment the tool includes a network server, a plurality of access points and a mobile client. The network server is used to create and distribute data packets. The plurality of access points are coupled to send and receive data packets from the server. The mobile client is in wireless communication with the plurality of access points. The client has a two-dimensional surface area map on a data grid. The client includes instruction to compute throughput and packet error rate at selected locations within a network coverage area when the client receives data packets sent by the network server. The client displays the throughput and packet error rate on the two-dimensional surface area map to provide a site survey of the wireless network coverage.
