Corning RIU-BTSC-AWS Conditioner, +10 to +36 dBm Input Range.

The Quad-Band Radio Interface Unit (RIU-4) provides
a scalable, cost-effective solution for adjusting the RF
signal source from a number of host base-transceiver
stations (BTS) or bi-directional amplifiers (BDA)
and feeding the conditioned RF signals to Corning
MobileAccess DAS coverage systems.
The RIU-4’s scalable design is ideal for large
deployments, and can easily expand to support
operator’s long-term needs. Each RIU-4 unit can
support up to four cellular services in a stand-alone
mode, whereas additional different services/bands (up
to 6) can be supported when two units are connected
in a Master/Slave configuration. Each unit supports up
to four 4-port Base Units (or two 8-port Base Units),
whereas additional Base Units (up to four 4-port or two
8-port Base Units) can be supported when utilizing the
Expansion Kit.

Remote control and monitoring is provided through a
System Controller (SC-450) connection, and enables
adjusting the RF input power level from the BTS or
BDA to the system and configuring the Automatic Gain
Control (AGC) function to ensure a constant level of
RF input to the system. Controlling Uplink RF signal is
facilitated as well to provide UL Noise level reduction
when necessary
