More than 60% of First Fresnel Zone must be cleared for acceptable performance.
6. Secured Mounting is important
If the mounting is not secured and shakes during wind, the performance might be
drastically reduced.
7. Remember to set correct Distance for long distance connection
Without setting the correct distance parameter (or ACKtimeout), the Bridge might not
even transmit data at all.
8. Use just enough output power
Excessive output power not only creates serious interference for everyone, it actually
can reduce the performance. An RSSI value around 60dB provides the optimal
performance.
9. Always do a site survey for antenna alignment
Most AirLive APs have site survey and signal survey function. It is important that the
antennas are aligned properly. If you are setting up 5GHz bridge, please use “11a”
mode first for antenna alignment. You can change to Super or Turbo mode after the
connection is established.
10. Use the correct Super or Turbo modes
• 11a mode (normal-A): This is the IEEE standard for WiFi operating in 5GHz
frequency band. 11a is the most stable mode. If you are getting packet loss or
disconnection using Super-A orTurbo-A mode. Please use 11a mode instead.
• SuperA without Turbo: Super-A adds Bursting and Compression to increase the
speed over 11a mode. If you live in countries that prohibit the channel binding
technology (i.e. Europe), you should choose “Super-A without Turbo) if you need
more speed than 11a mode. However, this mode is not as stable as 11a mode or
Super-A with Turbo-A modes.
• Super-A with Static Turbo: Turbo mode uses channel binding technology to
increase the speed further over Super-A and 11-A mode. This mode might not be
allowed in countries that prohibit channel binding (i.e. some EU countries). This
mode will always turn on the turbo mode in al conditions
• Super-A with Dynamic Turbo: Dynamic Turbo mode will be turn on only when
adjacent channel is not used. It is also know as intelligent turbo mode. This mode
might not be allowed in countries that prohibit channel binding (i.e. some EU
countries).
