modular construction with separate modules for -48VDC Input
Power Supply,
Exciter, Power
Amplifier, Receiver and Base Radio Controller, thereby
simplifying repair.
- Flexible Configuration - Several configurations are available
with each cabinet supporting a total of 6 base radios.
Up to 24 base radios can be supported on one RX antenna
and up to
12 base radios on one TX antenna. Each site can have
up to five
STR 3000 sub-systems for a total of 30 base radios at a
site.
- Easy installation - Base radios and the Radio Frequency
Distribution System are pre-packaged in a single cabinet

Product Description
Motorola's Quantar Data Base Station (DBS) Repeater
can provide you with the vital connection between landline and
radio communication
environments. It is a solid-state transmitter designed to
support high speed, reliable data communications in 800 and 900
MHz
systems.
Key Capabilities
- Full Duplex Operation - Motorola's Quantar DBS
uses full duplex operation over a 4 wire Type 5 or 3002 grade
phone line, to
optimize data throughput.
- Data Error Correction - With the Quantar DBS, data received
from mobile or data terminals can be corrected for errors
before being forwarded throughout your network, helping
maintain data
integrity.
- Protocol Conversion - Protocol Conversion in the base
station virtually eliminates the process of reprogramming
a host computer
to use a protocol compatible with the network.
- Radio Signal Strength Information (RSSI) Option - RSSI
allows the network controller to choose the optimum
transmitter to
communicate to a specific terminal. Using RSSI, hundreds
of data terminals
can be supported on a single channel.
Features
- Configurable Transmitter - The Quantar DBS is
designed to support up to 19.2 kbps data transmission for 800
MHz and 9.6 kbps
data for 900 MHz. Transmitter power is configurable, permitting
communication coverage to be customized for mobile and
portable terminals.
- Maximum Flexibility in a Compact Design - The compact dimension
of the Quantar DBS helps you optimize site space usage,
while the software-intensive design allows you to make
upgrades and
complete system migrations easily.
- Switching Power Supply - The Quantar DBS features a switching
power supply that functions over a wide range of voltages
and frequencies, meeting a variety of needs and changing
system
requirements.
- Superb Reliability and Serviceability - The base station's
battery reversion capabilities in the event of a power
failure, comprehensive diagnostics, self-testing, and
system alarm reporting
helps you make sure your system is always operating
in its optimum condition.
