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.

Building a Channel Map

After completion of a site survey, the next step is to build a channel map by selecting

the channels for your networks. Use the following channel map worksheet to select

the most appropriate channels for your networks.

NOTE: For your convenience, the channel map worksheet is repeated in the

appendix on page 19. A checklist of the steps required to complete the worksheet is

also provided.
