Antenna System
The antenna system is constituted by all RF transmission and reception
antennas, directed to cover the same area or multi-casting congurations.
Base Transceiver Station (BTS)
A BTS is a unit operating on a set of frequencies in one cell.
Basic Conguration
A basic conguration is a specied set of transceivers, CDUs, and in
some cases, TMAs, connected to one antenna system.
A basic conguration can be multiplied or used in combination with
other basic congurations to build the needed site equipment.
Variations of a basic conguration may exist, differing in cable lengths.
This depends on factors such as implementation in different cabinets.
Radio Base Station (RBS)
An RBS is all equipment in an Ericsson base station, and may be
comprised of several BTSs.
Each RBS has one DXU, controlling a maximum of 12 TRXs.
Site/Cell Conguration (SCC)
The SCC is a geographical concept describing how an area around one
RBS site is divided into radio trafc areas. The following types of site
are dened:
Omni-site Radio coverage in one 360 degree sector,
that is in one area, using one BTS.
2sector site Radio coverage in two sectors, that is two
distinct areas, using two BTSs.
3sector site Radio coverage in three sectors, that is
three distinct areas, using three BTSs.
