RF Products Crestron Best Practices

Improving Wi-Fi Network Performance

Extra communication parameters can be configured on Wi-Fi networks to improve

the performance of the network. If you are using a Crestron access point, those

parameters are configured for the network using the wizard. If you are using a third-

party access point, you can download configuration files from the Crestron website

(www.crestron.com/onlinehelp).

Increasing Reliability

The following are some tips beyond the channel selection discussed in previous

sections that can help improve the reliability of touchpanels on a Wi-Fi network:

• Do not hide the SSID (service set identifier). Hiding the SSID can be

troublesome for the TPMC-4X and TPMC-10 touchpanels.

• WPA and WPA2 authentication can be problematic; therefore, use WEP or

disable security for the best performance.

NOTE: Using WEP or disabling security can be risky in certain

environments. If using WEP, it is recommended that MAC address filtering

also be used. Disable security only if the site is safe from security threats.

• Do not attempt a “roaming” configuration with the TPMC-4X, TPMC-4XG,

or TPMC-10. Those touchpanels do not perform the hand-off between

access points well. Attempt a roaming configuration with the TPMC-3X or

TPMC-8X only.

Improving Reconnection Time

Several parameters can be set to improve Wi-Fi reconnection time:

• If you desire a secure network without reconnect delays, use an open key

static WEP encryption in combination with MAC address filtering.

NOTE: Encryption provides a more secure network but it can also increase

the reconnection time. WEP Shared authentication and WPA/WPA2

increase the reconnect time for touchpanels.

• Use a static IP address on the touchpanel so that it will not have to wait to

receive a DHCP address before communicating with the control system.

• Configure only one access point in each touchpanel. By doing this, the

touchpanel will only scan for one network and will not attempt to look for

other networks.

• Because the wireless radio does not shut down until the “power down”

timeout is reached, you can improve performance and maintain battery life

by setting the Standby and Power Down timeouts for your customer. It is

recommended that the Standby timeout be set to a minimum time (1-2

minutes) to turn off the screen backlight but keep the Wi-Fi radio running

and connected to the system. The Power Down timeout can then be set to a

longer time based on the user’s preference (15-30 minutes is

recommended).
