Product Specification for RBS 2302
5 Product Specification for RBS 2302
This chapter describes the architecture of the RBS 2302 and specifies its
the characteristics and performance.
5.1 Terminology
TN Power System TN Power System is a power distribution
system having one point directly earthed.
The exposed conductive parts of the
installation are connected to that point by
protective earth connectors.
TT Power System TT Power System is a power distribution
system having one point directly earthed.
The exposed conductive parts of the
installation are connected to earth
electrodes electrically independent of the
earth electrodes of the power system.
IT Power System IT Power System is a power distribution
system having no direct connection to
earth. The exposed conductive parts of the
electrical installation are earthed.
5.2 General
The RBS 2302 satisfies the need for ’hot spot’ capacity in small areas,
such as part of a city centre or a shopping mall, as well as ’fill in’
coverage.
The main focus with this product is to reduce site cost and make it
easier for operators to find sites, which will ensure operator profitability
of a micro cell network.
The RBS 2302 can be expanded with up to six transceivers by adding
extra RBS 2302 cabinet to a site.
To be able to support the idea of a small RBS that can be located
almost anywhere, some functional limitations has been made:
• No antenna supervision.
• No RF cable supervision.
The weather-proof cabinet and design make it ideal for installation
indoor, outdoor, on poles, walls or masts.
Integral antennas can be ordered as omni or sector antennas. Apart
from this there is always a possibility to connect external antennas.
A multicasting box is provided to make it possible to combine the
antenna signals from two TRXs into one antenna feeder.
For sites located in places with extreme heat an active cooling device
may be provided as an option.
An extended OMT port (a permanent cable from the RBS to a more
convenient place) is provided as an option.
