Glossary

ARFCN	Absolute Radio Frequency Channel Number
BCH	The BCH (Broadcast Channel) is a beacon which is always
	turned on so that mobile can look out for it when trying to find
	service. A useful BCH always carries information in timeslot 0.
	The BCH ARFCN has to be active in all timeslots to allow
	mobiles to synchronize to other cells. There are a number of
	other areas to the BCH:
	• TCH (Frequency correction Channel) is a special burst on the
	BCH. It has special fixed bit sequences to allow the mobile to
	tune onto the midamble.
	• SCH (Synchronization Channel) has a burst with extended
	midamble. It is used by the mobile to adjust its internal timing
	and get synchronized to the multiframe sequence.
	• BCCH (Broadcast Control Channel) has information encoded
	on it which identifies the network. It also carries lists of the
	channels in use in the cell (BA and CA tables).
	• CCCH (Common Control Channel) is like a message board.
	Like the FCH, SCH, and BCCH, it can be received by any
	mobile. Sub-channels like PCH (Paging Channel) and AGCH
	(Access Grant Channel) are posted on the CCCH.
BCCH	Broadcast Control Channel. A unidirectional channel used by
	the base station facilities to broadcast control information to
	land mobile units.
Bit Error Rate The digital receiver test that measures of the quality of the
	recovered information (sensitivity and usable input level range)
	equivalent to SINAD in an analog system.
BS	Base Station
BTS	Base Transceiver System
