Product Specification for RBS 2302
The base colour of the RBS is Grey (NCS S2502-R), but it is possible
to order the front sun-shields in different colours, which can make the
RBS more discrete depending on the environmental surroundings.
The RBS consists of the following main physical units: Mounting Base,
Cabinet, Antennas and Sun-shield. This will support a routine of
installing the Mounting Base prior to the Cabinet arrival.

The prime technical concerns have been to implement a RBS that:
•
has a small size (volume and weight), and an appearance suitable
for a discrete installation ("landlord friendly").
•
has high channel capacity, two transceivers giving total of 15
traffic channels if configured to one cell. The RBS 2302 may be
configured with up to six transceivers in one cell by adding extra
RBS 2302 as extension cabinets.
•
is characterized by low need for preventive maintenance.
•
has high MTBF
•
has versions for the different system standards GSM 900, GSM
1800 and GSM 1900.
•
includes all functions needed for a complete installation of a radio
base station, including standard interface G703 2048 kbit/s or DS1
1544 kbit/s to transmission network, AC mains power, battery
backup and a choice of internal or external antennas.
•
supports Linear Cascade connection on the transmission interface.
•
has an extended OMT-port that makes it possible for connection
of the OMT at ground level if the RBS 2302 is mounted high on
a wall or a pole.
•
includes an optional fan-unit which extends the upper temperature
limit to +55 C
