Indoor Unit, Antenna and Outdoor Unit, and the
Interconnection Cable, you need to commission the
System. This procedure describes how to set up the
minimum requirements for successful µLink System
operation.
Information
Required
Before commissioning the system, you should know
the proposed frequency band plan (Tx and Rx) for
each station, and the PN sequence for the link.
Commissioning
Procedure
Setting-up Procedure
Perform the following steps at both stations:
• Locate the far site and point the antenna to the
antenna at the far site, as accurately as possible.
• Switch the IU power ON.
• Install and Access the µLink Management
Software (refer to Chapter 4 of this manual).
• Configure the radio channel as required.
• Configure the Tx and Rx PN sequences.
• Set the Tx power to maximum.
Beaming-up
1. Check the RSSI and BER levels.
2. Align the antenna until the Maximum RSSI and
minimum BER levels are attained.
Set Critical Parameters
1. Reduce the Tx power until an RSSI of between -65
and -70 dBm is obtained. This is important to
avoid interference to co-located systems.
