Antenna System
The antenna system is constituted by all RF transmission and reception
antennas, directed to cover the same area or multi-casting configurations.
Antenna Sharing Unit (ASU)
An ASU is a unit used for sharing RX antennas between RBSs.
Base Transceiver Station (BTS)
A BTS is a unit operating on a set of frequencies in one cell.
Basic Configuration
A basic configuration is a specified set of transceivers, CDUs, and in
some cases, TMAs, connected to one antenna system.
A basic configuration can be multiplied or used in combination with
other basic configurations to build the needed site equipment.
Variations of a basic configuration 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 Configuration (SCC)
The SCC is a geographical concept describing how an area around one
RBS site is divided into radio traffic areas. The following types of site
are defined:
Omni-site Radio coverage in one 360 degree sector,
that is in one area, using one BTS.
