Airaya – Fast and affordable outdoor wireless bridges
This screen provides the following data:
Bridge Status
Current Status. Current state of remote bridge. While authenticated, the
remote bridge status should indicate "Associated".
Uptime. Elapsed time the bridge has been up and since the last power
cycle.
Operating In. Specifies the general frequency range remote bridge is
operating in.
Security Type. Displays the current Security Type settings for this bridge.
Signal Strength, Radio rates, and Quality:
Signal Strength Indicator. Signal Strength is a good indicator of overall
network quality. Lower values (below 15) indicate a bridge will only be able
to communicate at low data rates. Higher signal strength values (above
15) indicate the bridges have the ability to run at faster data rates.
NOTE
Tip: To allow WirelessGRID bridges to monitor their own signal strength
and dynamically adjust data rates, you can set Data Rate on the Radio
Settings tab to "Best". This will allow the bridge to monitor signal
strength on a packet-by-packet basis, adjusting data rate accordingly. If
signal strength is not optimum, the radio will adapt and change to a lower
modulation, which in turn lowers the radio data rate, but provides a higher
effective TCP/IP data rate by increasing radio receiver sensitivity and
reducing the packet error rate. This adaptive data rate ability provides
for better overall quality and reliability of the link.
Last Transmitted. Signal Strength values (measured in dBm) for the last
packets transmitted. Signal Strength is a good indicator of how your link
will run. When “best” data rate is selected low values indicate the local and
remote bridge are operating in a slower mode.
Last Received. Signal Strength values (measured in dBm) for the last
packets received.
Data Rate - Sending. Displays the current radio data rate being used to
send data between the local and remote bridge.
