Crestron TPS-6X Series Isys™ 5.7” Wireless Touchpanels
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.
