You do not require a license to operate radio equipment in the 2.4 GHz band where the Cisco Aironet WLAN equipment operates. As a result, other transmitters can broadcast on the same frequency that your WLAN uses.
A spectrum analyzer is the best tool to determine the presence of any activity on your frequency. The Carrier Busy test available in the Test menus of Cisco Aironet bridges functions as a substitute for this item. This test generates a rough display of activity on the different frequencies. If you suspect radio interference with transmission and reception on your WLAN, turn off the equipment that operates on the frequency in question and run the test. The test shows any activity on your frequency and the other frequencies on which the equipment can operate. You can thus determine if you want to change frequencies.
