Chanalyzer Capture of a Poor RF Environment Created by Cordless Phones
Microwave Oven Interference
The following is an example of interference emitted from a microwave oven.
A microwave oven does not have the high peaks of interference that the 2.4 GHz
cordless phone has; however, the radiation of a microwave oven affects most
channels. Although the radiation usually does not cause major issues, it can
periodically reduce performance and cause instability.
Chanalyzer Capture of a Microwave Oven’s RF Interference
802.11g Network Interference
The following is an example of a very strong Wi-Fi 802.11g network operating on
channel 6 (the channel 6 boundaries are highlighted). A network this strong causes a
great amount of interference with any Crestron devices operating in the channel or in
the overlapping 802.15.4 channels (16–19). As a result, 802.11 channel 6 and
802.15.4 channels 16–19 must be avoided when selecting operating channels for
Crestron gateways. The level of interference drops off sharply outside the
highlighted area; therefore, devices can be installed in the same environment as long
as they use other channels for communication.
