DIY 2,4 GHz spectrum analyzer
This austere website helps you to make a your very own 2,4 GHz spectrum analyzer.
What in the world is this electronic device for ? It finds the best channel for your Wi-Fi (802.11b) network of course !
Between the micro-wave ovens, video transmitters, DECT phones and other wireless gadgets all using the same frequencies as Wi-Fi, it is often useful to know which frequency is best to use. Our Wi-Fi software can only detect Wi-Fi signals, ignoring all the other noise.
With a spectrum analyzer, you can see which frequencies are available, and tell your Wi-Fi hardware to use the corresponding channel !
While waiting for more intelligent technologies capable of dynamically choosing a channel depending on the interferences, it is best to opt for the analyzer solution if your network encounters slow transfers or loss of data.














Error….
DECT phones are NOT in the 2.4 GSM band.
Frequency: 1880-1900 MHz in Europe, 1920-1930MHz in the US
Now my error….
I meant not in the 2.4 ISM band. (here in the US)
