Drive Testing Requirements
Collecting Data
To ensure proper repeater operation, drive test all of the following areas:
•
Repeater coverage area
•
Transition zone, between the donor base station coverage area, and the repeater
coverage area
•
Soft hand-off zones, between the repeater and adjacent cell sites
For GSM networks, it is recommended that you accumulate data for both the forward and reverse
link, at the same time. Usually, this requires invoking “call trace,” or some similar function within the
switch. Once invoked, the switch logs the test call by time stamp. You can later correlate this to the
forward link data.
This method helps you to more-accurately analyze the link balance, and to identify areas of high
errors and/or high Mobile_TX parameters.
Analyzing the drive test results might require a change in network timing parameters, and/or
adjustment of the repeater subscriber antenna. That is, you must optimize the repeater, using the
same methods as you use for a base station.
