ZigBee Channels
The ZFR1800 Series System operates on an Institute of Electrical and Electronic
Engineers (IEEE) 802.15.4 ZigBee network.
This ZigBee network has 16 channels available for use (Channels 11 through 26,
shown in Figure 23). In North America, the ZFR1800 Series System uses channels
11 through 25. By default, the ZFR1810 coordinator is configured for use in North
America, and uses channels 15, 20, and 25.
These channels were selected for the ZFR1800 Series System because they do not
overlap with channels used on an IEEE 802.11 WiFi network. To illustrate,
Figure 23 compares the channel spacing of the ZigBee and WiFi networks. Notice
that the IEEE 802.15.4 channels of operation used by the wireless Metasys systems
do not overlap and, therefore, avoid interference with the WiFi network.
Use CCT to select a different subset that has been preselected based on the country
or region of use. These channel subsets were selected because they do not overlap
or interfere with channels used on WiFi channels used in those regions. To
illustrate, Figure 23 is a diagram showing the channel spacing of the ZigBee and
WiFi networks for North America.
