Key System Features
•
Superior RF performance
, particularly in the areas of IP3 and noise figure.
•
High downlink composite power
and
low uplink noise figure
for support of a
large number of channels and larger coverage footprint per antenna.
•
Software configurable
Main and Expansion Hubs. Thus, the frequency band can
be configured in the field.
•
Either single-mode or multi-mode fiber
can be used, supporting flexible cabling
alternatives (in addition to standard Cat-5, Cat-5E, or Cat-6 screened twisted pair
[ScTP]). You can select the cabling type to meet the resident cabling infrastructure
of the facility and unique building topologies.
•
Extended system “reach.”
Using single-mode fiber, fiber runs can be as long as
6 kilometers (creating a total system “wingspan” of 12 kilometers). Alternately,
with multi-mode fiber, fiber runs can be as long as 1.5 kilometers. The Cat-5/5E/6
ScTP cable run can be up to 100 meters recommended maximum, or up to 170
meters when using a Cat-5 Extender.
•
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.
– 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 (all RAUs
except UMTS-1).
•
Firmware Updates
are downloaded (either locally or remotely) to operating sys-
tems when any modifications are made to the product, including the addition of
new software capabilities/services.
•
Extensive OA&M capabilities
, including fault isolation to the field replaceable
unit, automatic reporting of all fault and warning conditions, and user-friendly
graphical-user interface OA&M software packages.
