By entering a network into the NETWORK column of the channel map worksheet,
you reserve the associated channel for that device and ensure 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: a 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 networks.
4. Enter the FocalPoint networks.
5. Enter the infiNET and infiNET EX 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 C2N-MNETGW be set to select the operating channel automatically.
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 networks, and then repeat steps 4 and 5.
