System Overview
2-2 InterReach Fusion Wideband Installation, Operation, and Reference Manual
CONFIDENTIAL D-620616-0-20 Rev A
• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO,
and Paging
The Fusion Wideband system supports two configurable bands:
• Band 1 in 60 MHz and can be configured for 2100 MHz
• Band 2 in 75 MHz and can be configured for 1800 MHz
Both bands support all protocols.
Refer to Table 2-4 for a specific list of supported RAUs.
Key System Features
• Multi-Band, supports two full band frequencies for spectrum growth.
• Superior RF performance, particularly in the areas of IP3 and noise figure.
• High downlink composite power and low uplink noise figure enables support of
a large number of channels and larger coverage footprint per antenna.
• Software configurable Main and Expansion Hubs allow the frequency bands to
be configured in the field.
• Either single-mode or multi-mode fiber can be used, supporting flexible cabling
alternatives (in addition to standard CATV 75 Ohm cabling). You can select the
cabling type to met the resident cabling infrastructure of the facility and unique
building topologies.
• Extended system “reach.” Using single-mode fiber, fiber runs can be a long as 6
kilometers (creating a total system “wingspan” of 12 kilometers). Alternatively,
with multi-mode fiber, fiber runs can be as long as 500 meters.
• Standard 75 Ohm CATV cable, can be run up to 130 meters for RG-59 cable
(140 meters for RG-6; 235 meters for RG-11 using CommScope 2065V, 2279V,
and 2293K cables).
• Flexible RF configuration capabilities, including:
• System gain:
– Ability to manually set gain in 1 dB steps, from 0 to 15 dB, on both down-
link and uplink.
•RAU:
– RAU uplink and downlink gain can be independently attenuated 10 dB in 1
dB steps.
– Uplink level control protects the system from input overload and can be
optimized for either a single operator or multiple operators/protocols.
– VSWR check on RAU reports if there is a disconnected antenna.
• Firmware Updates are downloaded (either locally or remotely) to the system
when any modifications are made to the product, including the addition of new
software capabilities and services.
