Repeater Types
The following repeater types are currently available:
• Channel selective GSM repeater
• Channel selective CDMA repeater
• Channel selective high power CDMA repeater
• Band selective repeater with fixed bandwidth
• Band selective repeater with adjustable bandwidth
• Combined repeater
In the OMT32, the channel selective 900, 1800, and 1900 systems are
called GSM, DCS and PCS respectively, even though these systems may
have different names in other parts of the world.
Channel selective GSM repeater
A channel selective GSM repeater can be equipped with two, four, six or
eight channels. This repeater type is used for channel selective systems,
such as GSM, DCS, PCN and GSM 1900 (PCS).
Channel selective CDMA repeater
A channel selective CDMA repeater can be equipped with one or two
channels. This repeater type is used for digital code division systems in
accordance with IS-95 or J-std-008 standard.
Channel selective high power CDMA repeater
A channel selective CDMA repeater like the previous one, but equipped
with a 6dB (typically) BA (Booster Amplifier) unit.
Band selective repeater with fixed bandwidth
A band selective repeater with fixed bandwidth has fixed filters for a
certain bandwidth. This repeater type is used for analog or digital
systems, such as NMT, GSM, TACS, ETACS, AMPS, DAMPS and CDMA.
Band selective repeater with adjustable bandwidth
A band selective repeater with adjustable bandwidth has filters that can
be set to various bandwidths. This repeater type is used for analog or
digital systems, such as NMT, TACS, ETACS, AMPS, DAMPS and CDMA.
Combined repeater
Some of the above mentioned types can be combined in the same repeater
chassis and be in operation in parallel.
