The R20 UBS Macro BTS supports single band 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.
What is covered in this manual?
The UBS Macro BTS Hardware Installation manual describes the installation of Motorola
supported configurations of the UBS Macro BTS system. The UBS Macro BTS system supports
either the 800 MHz or the 1.9 GHz RF band and IP -packet backhaul. In addition, CDMA 1X and
CDMA EV -DO channels are supported as well as Open Transport Interface (OTI) for IP -packet
backhaul via Ethernet. The UBS Macro BTS frame can also be configured for +27 V DC
operation, optional -48 V DC or optional 220 V AC operation.
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
• Dual path, Main and Diversity , RX antennas
UBS Macro BTS frames are also configured for low , mid, or high capacity . Capacity is determined
by the quantity of sector carriers and traffic channels supported by the frame. The quantity of
sector carriers is a function of the quantity of XMIs. The quantity of traffic channels is a function
of the quantity of modems. Because the modems are inside the DMI, the quantity of DMIs is a
capacity factor . The capacity of a UBS Macro BTS frame is essentially based on the following:
• low capacity - one XMI and up to two DMIs
• mid capacity - two XMIs and two DMIs
• high capacity - more than two XMIs (four XMIs maximum) and more than two DMIs (four
DMIs maximum)
