SECTION 2 InterReach Unison Accel

System Description

InterReach Unison Accel is a wireless networking system that is designed to handle
both wireless voice and data communications over licensed frequencies. It provide
high-quality, ubiquitous, seamless access to the wireless network in smaller build­ings, including:

• Office buildings

• Hospitals
Accel provides the same RF characteristics as InterReach Unison, which is designed

for large public and private facilities such as campus environments, airports, shop­ping malls, subways, convention centers, sports venues, etc. Accel uses microproces­sors to enable key capabilities such as software-selectable band settings, automatic
gain control, ability to incrementally adjust downlink/uplink gain, end-to-end alarm­ing of all components and the asso ciated cable infras tru cture, and a host of additional
capabilities.

The Accel system supports major wireless standards and air interface protocols in use
around the world, including:

• Frequencies: 800 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz

• Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM, iDEN,

• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT,
and Paging

620021-0 Rev. A

Key System Features

• 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 Hub. Thus, the frequency band can be configured in the
field.

• Standard Cat-5 or Cat-6 (Cat-5/6) screened twisted pair (ScTP) cabling. The
Cat-5/6 ScTP 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, 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).

• 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 package.
