Key System Features
• Superior RF performance, particularly in the areas of IP3 and noise figure.
• High downlink composite power (+26 dBm), IP3 (+38 dBm) and low uplink
noise figure (22 dB for a system with 8 RAUs), enables support of a large number
of channels and larger coverage footprint per antenna.
• The Main Hub and the Expansion Hub are software configurable. Thus, the fre-
quency band can be field configured.
• The system supports flexible cabling alternatives, allowing the use of either mul-
timode or single-mode fiber (in addition to standard Cat-5 or Cat-6 [Cat-5/6]
twisted pair). Cabling type can be selected to meet the resident cabling infrastruc-
ture of the facility and unique building topologies.
• Extended system “reach”. Using multimode fiber, fiber runs can be as long as
1.5 kilometers. Alternately, with single mode fiber the fiber run can be as long as
6 kilometers (creating a total system “wingspan” of 12 kilometers). And the
Cat-5/6 twisted pair cable run can be up to 100 meters recommended maximum
(150 meters with RF performance degradation).
• Flexible RF configuration capabilities, including:
• System gain:
– Ability to manually set gain in 1 dB steps on both downlink and uplink.
• RAU:
– RAU uplink and downlink gain can be attenuated 10 dB.
– Uplink level control protects the system from input overload and can be
optimized for either a single operator or multi-operators/protocols.
– VSWR check on RAU reports if there is a problem with the antenna.
• The system firmware effectively “future proofs” the product. When any modi-
fications are made to the product, including the addition of new software capabili-
ties/services, systems that have already been installed can be upgraded simply by
downloading new firmware (either locally or remotely).
• Extensive OA&M capabilities, including fault isolation to the field replaceable
unit, automatic reporting of all warnings and alarms, and user-friendly graphi-
cal-user interface OA&M software packages.
