Base Station Components
Base Transceiver Station (BTS)
The BTS consists of the RF Power Amplifiers (PA’s), the digital circuit cards, the backplane,
and the mechanical enclosure or housing. It performs the signal processing and RF transmission
for the system. There are two types of chassis: Combo and Split. The Combo Chassis is used
primarily with 2.4 GHz systems. The Split Chasses is used for all other (2.3, 2.5, 2.6 GHz)
systems (Figure 3).
The chassis is compartmentalized into two sections - the RF shelf and the Digital shelf. The BTS
connects to the network using a 10/100 Base-T Ethernet connection or up to 8 T1 interfaces. Up
to three BTS assemblies can be installed per system, depending on the configuration.
