Alvarion SW VERSION 5.1 system manual Commissioning

Aligning the Subscriber Unit Antenna

NOTE

In some cases, the antenna may need to be tilted to ensure that the level at which the SU receives transmissions from the AU (and vice versa) is not too high. As a rule of thumb, if the SU is located at a distance of less than 300 meters from the AU, it is recommended to up-tilt the antenna by approximately 10° to 15°. To guarantee a safety margin from the saturation level, the SNR should not be higher than 50 dB. The orange LED of the SNR bar indicates that the SNR is higher than 50 dB.
