6.4 Tips for Improving Wireless Data Communications
A suitable installation site should locate the antenna in a transmission path as
unobstructed as possible; in the direction of the associated router.
When a wireless transducer is linked to a router, a yellow LED on the WI-FI option
board remains on. Received Signal Strength Indication (RSSI) is an important
indicator of wireless link quality. The higher the RSSI, the stronger the performance a
wireless system can provide. Signal Strength is calculated by a wireless transceiver
and can be viewed on Administration-System Information - WI-FI LAN - Active
Settings of the device home page (see Figure 47).
If constant interference is present in a particular frequency zone, it might be
necessary to change the operational channel in the WI-FI network. If interference
problems persist, try reducing the length of data streams. Groups of short data
streams have a better chance of getting through in the presence of interference
than do long streams.
