WIFI analyzer on Android
The WIFI analyzer app is a nice utility to scan the WIFI landscape in your location;
It shows all WIFI networks currently available with channel numbers.
Also it shows at which channel the currently used WIFI network could best be set based on the WIFI signal landscape. In this example the WIFI signal can best be moved to channel 12, 13 or 14.
Also it shows the worst and most used channel which is channel number 5. Current channel set is 8.
This means more interference compared to a channel not shared with any other WIFI Access Point.
Modern WIFI Access Points have 2 or 3 separate WIFI frequency bands with each a selection of channels to get the best possible speed and least interference with other competing WIFI access points.
