RF Products Crestron Best Practices

An example of a channel map follows and is based on the sample list of network

products in the table on page 6 and on the sample site survey on page 8.

In the channel map example, wireless networks, shown in italics on the channel map

worksheet, are entered as follows:

1. Too much interference exists on Wi-Fi channel 1 and on 802.15.4 channels

11-14; therefore, those channels are eliminated.

2. Wi-Fi channel 6 is the channel that is most free from interference; therefore,

a TPMC-4XG network uses that channel. 802.15.4 channels 16-19 are then

unavailable to any other devices.

3. Channel 11 is the only free Wi-Fi channel remaining for another

TPMC-4XG network. 802.15.4 channels 21-24 are then unavailable to any

other devices.

4. There are no more free Wi-Fi channels remaining for TPMC-3X and

TPMC-8X networks; therefore, 802.11a (5.8 GHz) channels are selected for

the TPMC-3X and TPMC-8X networks.

5. 802.15.4 channel 20 is free; therefore, the TPS-6X network is set to that

channel.

6. 802.15.4 channel 15 is free; therefore, the MLX-2 network is set to that

channel.

7. 802.15.4 channels 25 and 26 are free; therefore, the Lighting network is set

to channel 26. Channel 26 is the channel most removed from Wi-Fi

networks and therefore should be the least susceptible to interference from

Wi-Fi networks. Channel 26, however, also has the shortest range in most

Crestron products and therefore may be less reliable than other channels.

Careful examination of the site survey is necessary to determine the most

appropriate channel assignment.

As a result of careful testing and planning, each network is positioned so that

it will not interfere with the other networks or receive large amounts of outside

interference.
