6.8.8 Beacon Transmit Test
The Beacon Transmit test is used so that the RF transmission from a nanoBTS can be
measured without the nanoBTS having to be connected to a BSC. This is likely to be
particularly useful during initial installation, when the BSC (or the communications link
to the BSC) may not yet be available. It enables walk tests to be done using a test
mobile to check coverage, and path loss between the transmitting nanoBTS and other
nanoBTSs to be measured using the Network Listen Channel Usage test.
The Beacon Transmit test uses the normal downlink transmitter to transmit a
continuous beacon signal on a specified channel, with a specified Base Station Identity
Code (BSIC) and at a specified power specified. The beacon transmission conforms to
the normal GSM slot, frame and multiframe structures. Slot 0 carries a full BCCH
channel combination, and all other slots carry idle TCH (i.e. contain Dummy Bursts).
Slot 0 has the normal FCCH and SCH, which carries the specified BSIC. The BCCH
carries SysInfo 2, SysInfo 3 and SysInfo 4, but the CCCH channels are empty and
Dummy Bursts are transmitted as required. The SysInfo messages mark the cell as
barred, with no neighbour lists or cell allocation lists. The PLMN is indicated as the
well-known GSM Test PLMN, 001-01.
Hint: Before running the Beacon Transmit test, you might want to use the Channel
Usage test to check that the ARFCN to be used is not already in use.
To use this test select the Transmit Beacon 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.
