800 MHz or 1.9 GHz RF band, up to two XMIs, up to two DMIs and one S SI. UBS
Macro BTS frame configurations with up to four XMIs and up to five DMIs will be
available in the future.
Introduction
The Motorola Universal Base Station (UBS) Macro BTS conforms to the TIA/EIA/IS -97E and
CDMA2000 for the CDMA Base Station performance specifications. It is a packet BTS that
operates in the 800 MHz or 1.9 GHz RF band.
The packet BTS has a packet backhaul network interface that can handle voice and data.
A packet BTS is equipped with IP -packet routing functionality . The packet BTS connects to
the Access Network (AN) using span lines. This configuration provides the packet backhaul
between the packet BTS and the AN .
UBS Macro BTS Frame Overview
The Motorola Universal Base Station (UBS) Macro BTS along with other external equipment
forms a 1X BTS that is part of the Motorola R adio Access Network (RAN).
The UBS Macro BTS is the interface between the Access Node (AN) in the RAN and the
Subscriber Units (SUs) that are operating in the UBS Macro BTS RF coverage area.

AN . This IP -packet backhaul interconnection is through T1/E1 span lines or high -speed Ethernet.
Control and bearer traffic data is exchanged between the UBS Macro BTS and the SUs. This
interconnection is by means of the CDMA2000 1X air interface.
The UBS Macro BTS air interface supports the following:
• Omni or 3–sector antenna configurations
• Single RF band operation only; 800 MHz or 1.9 GHz RF band
• Up to 120 W of total TX RF power output and up to 30 W TX RF power output per carrier in
omni; 20W per sector -carrier in 3 sector
• Dual path, Main and Diversity , RX antennas
