Figure 64 - BCCH Channel Usage Zoom
6.8.6 BCCH Information Test
In this test the nanoBTS decodes the system information messages that are being
broadcast on a set of channels and reports the values of attributes such as location
area code, cell id, and BSIC, as well as measuring RXLEV and RXQUAL. This takes
about 15 seconds per channel, because of the repetition rate at which the relevant
system information messages are transmitted.
If the BCCH Usage test has already been run, BTS Installer automatically uses the
results of that test to populate the ARFCN White List for this test, so that time is not
spent listening for system information messages that are not there. When viewing the
configuration of the test, you will see that the ARFCN White list has automatically been
selected as those detected with a BCCH. You can override this if you wish.
If you have not previously run the BCCH Channel Usage test, and you don’t set up
your own ARFCN White List, then all channels will be selected and the test will take a
very long time to run. As usual, you can apply a RX LEV threshold that only selects
ARFCN’s to decode the BCCH on if the power level is above the threshold. In the
event of accidentally starting a test that will run for too long, press the “Stop” button on
the toolbar. This sends a message to the BTS requesting that it cease the test.
To use this test select the BCCH Information tab on the left hand side of the Network
Listen window. Then, if you wish to view or change the configuration for the test, select
the Configure Test button located at the top of the screen.
