The Link Budget Calculator
The Link Budget Calculator is part of the FibeAir2000 Manager software and is found in the
Help menu. This useful utility enables you to calculate the expected performance of the wire-
less link and the possible configurations for a specific link range including antenna size, cable
loss and climate conditions. For full details, see Chapter 21.
Performance Monitoring
FA4800 Performance Monitoring constantly monitors traffic over the radio link and collects
statistics data for the air interface, TDM and Ethernet ports. It does so continuously, even
when the FibeAir2000 Manager is not connected.
Two types of logs are recorded:
• Monitor Log that records statistics on traffic rate and radio signal strength.
• Events Log that records when the rates fall above or below a predefined threshold.
See page 9-13 below.
Both the statistics Monitor log and events log can be saved as text files.
The Monitor Log
The Monitor Log records performance statistics for predefined intervals. You can save the
monitor log to a text file, as well as display the information in an on-screen report.
