Appendix A: The RF Spectrum
Crestron’s RF network provides 16 RF channels in the 2.4GHz ISM
*
band, specifically IEEE 802.15.4 channels 11 through 26. The 16
channels define the frequencies at which the RF device will
communicate.
RF devices on different channels will not communicate or interfere with
each other. However, since some of the channels are in the 2.4GHz ISM
band (as shown in the following diagram), interference can occur with
other devices using this band, such as 802.11b/g Wi-Fi devices, Crestron
infiNET™ devices or Zigbee devices, although the differing protocols
will not allow a link to be established or data to be transferred. Wireless
2.4GHz telephones and microwave ovens may also cause interference
with the network.
