Entering a network into the NETWORK column of the channel map worksheet
reserves the associated channel for that device and ensures that two devices are not
accidentally communicating on the same channel. Note the large size of Wi-Fi
802.11 networks compared to 802.15.4 networks. The Wi-Fi network occupies four
rows in the network list.
To build a channel map, refer to “Channel Map Guidelines” below.
Channel Map Guidelines
Enter wireless networks into the channel map as follows:
1. Eliminate the channels that were found to have too much interference
during the site survey.
2. Enter the 802.11b/g-only networks.
3. Enter the 802.11a/b/g/n networks.
4. Enter the Extended Range networks.
5. Enter the infiNET networks. Note that in most systems the infiNET network
should be set in Fixed mode to remain on the selected channel. For smaller
systems with only one or two infiNET gateways and minimal interference
detected in the system sweep, it is recommended that the gateway be set to
select the operating channel automatically.
6. Enter the infiNET EX networks. Note that infiNET EX networks are always
in Fixed mode and default to channel 15 first.
NOTE: If there is not enough free space to enter all networks on the channel
map worksheet using the steps above, select 802.11a channels for some or all
802.11a/b/g/n networks, and then repeat steps 4–6.
The following example of a channel map is based on the sample site survey on
page 10.
