Appendix A: The infiNET Spectrum
Crestron’s infiNET 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 infiNET device will
communicate.
Crestron’s infiNET devices on different channels will not communicate
nor 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 TPS-XTXRF devices, or Zigbee devices. However, 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.

To manage interference that may be present at installation time or may be
introduced later, the C2N-MNETGW has the ability to automatically
select a channel to operate on based on an evaluation of RF signal levels
on each channel. The gateway and devices are therefore designed to be
able to track and, if necessary, re-locate to channels with less
interference.
