Spectrum Analysis Showed All “G” Channels Are Poor Connectivity.

Hello all,

Some wireless users at a remote site have a really bad day. Their connections would drop in and out. So I set up a Spectrum Analysis and here what I found (see picture):

As you see in this picture, all channel in “G” band are affected by the device labeled as “Frequency Hopper (others)” with 80 MHz occupied bandwidth.
Has anyone seen this “Frequency Hopper”? I know 2.4GHz “G” band are opened to everything, but one device consumes all 80MHz spectrum seems too much. The only solution I have is to steer all users to “A” band, but many other device still need “G” band to function.

The best known frequency hopper is Bluetooth, but there are other generic frequency hoppers. These can cause problems for clients on all channels, as they'll hop all across the 2.4GHz band. Newer bluetooth devices are more WiFi friendly, but not all generic freq hoppers will be so polite.

Can you isolate down what the offending device is?
