Installing RF Devices

When installing RF devices, it is recommended that you perform the following steps

in the order listed below:

1. Create a network list.

2. Conduct a site survey.

3. Build a channel map.

4. Install and configure RF gateways.

5. Verify connectivity.

Creating a Network List

It is important to know which wireless networks are to be installed. To do so,

separate all the wireless devices to be installed into individual networks based on the

following guidelines:

1. Do not install more than three Crestron 802.11 devices on a single network.

2. Do not install more than 30 infiNET devices or more than 16 infiNET EX

devices on a single network⎯or as specified in the manual supplied with

the device.

3. To reduce the distances between gateways and devices, group the devices

based on their location rather than on their function. For example, instead of

creating separate lighting and HVAC infiNET networks, mix and match

devices based on their location.

4. Place 802.11b devices (for example, TPMC-10 and TPMC-4) and 802.11g

devices (for example, TPMC-3X, TPMC-4XG, and TPMC-8X) on different

networks.

5. When installing mesh networks such as infiNET and infiNET EX,

remember that battery-operated devices such as the CHV-TSTATRF and

MLX-2 do not act as repeaters and therefore do not extend the network

coverage.

6. To account for unexpected interference, do not exceed 75 percent of the

typical indoor network range.

One gateway is required for each individual network in the installation. The channel

of each network is dictated by the gateway; therefore, all client devices communicate

on the same channel as the gateway.

Keep in mind that some networks have the option of using either 2.4 or 5.8 GHz

bands (802.11a/b/g), such as when the TPMC-8X is used. Those networks should be

treated separately from networks that must use a 2.4 GHz band (802.11 b/g), such as

when the TPMC-4X is used. An example is shown in the following table.

NOTE: You can install multiple 802.11 devices on a single network. In the

following table, each device is given its own network for illustrative purposes only.
