ZigbeeThe Wi-Spy is a spectrum analyzer, and is not capable of reading at the protocol layer. However it will see noise generated by ZigBee as well as any other type of transmitting device in the same band. A Wi-Spy and Chanalyzer will not distinguish between ZigBee nodes, but will attempt to identify them by the shapes and center frequencies ZigBee transmitters create in the spectrum. Chanalyzer has built-in ZigBee labels to aid in troubleshooting interference. Keep in mind, if you are looking to troubleshoot wireless interference, you will need a non-ZigBee tool, which will show all types of wireless activity. The Wi-Spy is capable of doing this.
