A single DAS equipment headend delivers scalable and cost-effective RF coverage and

capacity. The Corning MobileAccess common equipment headend leverages

point-to-multipoint DAS architecture, connecting to one or more operator capacity

sources such as BTSs (base transceiver stations) and BDAs (bi-directional

amplifiers). At the common headend, radio frequency (RF) signals are converted from

RF electrical to RF optical for distribution to multiple remote locations or 'remote

ends' using low-loss, broadband fiber cabling (SMF/MMF). The modular Corning

MobileAccess headend architecture enables phased system commissioning, operator

on-boarding and sectorization planning for future capacity upgrades, while allowing

separate visibility and control of RF spectrum for each operator in multi-operator

deployments. Intelligent signal handling and low-loss elements ensure

operator-grade performance. Customers can leverage a single headend with any

number and types of Corning MobileAccess remotes (standard, medium, high power)

for full design flexibility that fits virtually any venue's topology. The common headend

also offers dedicated, plug-and-play RF conditioning modules and optional cost

savings with amplifier sharing for multiple operators.

The SC-450 enables remote and local management and offers centralized monitoring

via an integrated Web GUI and SNMP. The SC-450 maximizes system uptime by

locating faults in real time and allowing users to change individual RF parameters

including modulation.

The RIU conditions the RF downlink (DL) signals from an operator's signal source (BTS

or BDA) located inside the building. The RIU then custom tunes incoming signals in

order to ensure a constant level of RF before signals are passed to/from the Base Unit

(BU). RF uplink (UL) signals from subscribers' phones are received from the BU and

transported back to the operator's signal source (BTS or BDA) and to the operator's

macro network outdoors.

The quad-band Radio Interface Unit (RIU-4) adjusts RF signal source inputs, with

service-specific conditioning cards and sends signals to a wideband Base Unit (BU-4,

BU-8) where RF-electrical-to/from-optical conversion is performed before RF signals

are transported to multiple remotes (up to eight per BU) using low-loss fiber

(SMF/MMF). Each RIU includes a frequency combiner which supports optional

amplifier sharing for each capacity source and RIUs support 4x BU-4s and 2x BU-8s

(expansion kit available).

The RIU-4 unit can support up to four cellular services (RIU-IM supports three) in a

stand-alone mode, whereas additional different services/bands (up to six) can be

supported when two units are connected in a master/slave configuration.
