Project Description

Visualizes the spread of Wi-Fi access points across the available Wi-Fi channels, the amount of potential co-channel interference and the geolocation of the access points as known by Google.

Access Points are displayed across 5 channels. Interference inevitably does spread that wide, because the channel frequencies overlap (even more so than visualized, see diagram below). Ideally you should choose a channel that provides an exclusive use of the center channel and 4 adjacent channels. (e.g. you could choose to only use channels 1, 6 and 11 as seen in the corporate network screenshot)

Requirements

  • Windows XP SP3 or later
