354 Matrix ETERNITY NE System Manual
BCCH Selection
What's this?
BCCH Selection feature enables you to lock the Mobile Port of ETERNITY to a particular cell or channel or BTS
(Base Transceiver Station) to ensure better network availability, and minimize call drops due to bad signal/ network
failure, etc.
This feature is supported when SIMCOM-2G engine (SIM340-B01 or higher) or SIMCOM-3G engine is
installed in ETERNITY’s Mobile Card.
How it works
In the GSM network, each BTS is assigned one particular channel called as ARFCN (Absolute Radio Frequency
Channel Number), which is transmitted by BTS in BCCH (Broadcast Control Channel).
Now, when ETERNITY is switched on, the Mobile Port gets registered with the network on a particular BTS which
has the highest signal strength. However, the signal strength is not consistent. It keeps fluctuating, resulting in call
drop or poor voice quality.
Therefore, to avoid this, ETERNITY enables you to lock the Mobile Port to a particular cell or channel manually
after checking Signal Strength and Signal Quality of each cell.
How to configure
You can lock Mobile Port to a cell or a channel only through Jeeves.
