Figure 17 BCCH Information Test Results
Repeat tests 4, 5, 6 and 7 for each nanoBTS.
Step 8. Measuring path loss between nanoBTS
This test is designed to measure path loss between pairs of BTS sites so that the TX
power can be adjusted to achieve required coverage (typically 95%).
In this step each nanoBTS is selected in turn to transmit and the signal is measured on all
other nanoBTS in the building. The information from each test will be entered into a matrix
on the installation report, as shown below.
