InfiNET™ Gateway/Transceiver Crestron C2N-MNETGW
Appendix A: The infiNET Spectrum
infiNET 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.
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 Wi-Fi devices,
Crestron TPS-XTXRF 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.

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.
