1. System Overview
OR2-SBLP2-21F is used ‘For Mobile Operator use Only’.
OR2-SBLP2-21F is a digital repeater that provides optimized service with ICS
(Interference Cancellation System) to make the most efficient way to enhance WCDMA
network.
OR2-SBLP2-21F consists of the same components as normal RF repeater except DSP
(Digital Signal Processing) part and it can overcome oscillation problem caused by lack
of the isolation level between donor and coverage antennas.
OR2-SBLP2-21F can automatically compensate rapidly-changing input signals
including echo feedback signals caused by multi-path environment and it has
various advantages in terms of the operation and maintenance purposes.
OR2-SBLP2-21F consists of ICM (Interference Cancellation Module) that cancels
feedback signals, RF signal amplifier, MCU (Main Control Unit), and modem
(optional) to operate with NMS (Network Management System).

2. System Network Configuration
2.1. Service for Network
OR2-SBLP2-21F is the advanced antenna-embedded ICS repeater for indoor
coverage enhancement. This repeater adopted automatic setup feature with Plug & Play
to save time and installation cost. Network layout with OR2-SBLP2-21F is as follows.
[Figure - 1] System Network Configuration
OR2-SBLP2-21F receives input signals through donor antenna from Node-B for
DL and receives input signals through service antenna from a cell phone. They
are all air-coupled.
OR2-SBLP2-21F system consists of ICM (Interference Cancellation Module) that
cancels feedback signals between donor and service antennas, power supply,
digital board including controller, RF board for Tx/Rx amplifier and filtering, and
modem board to connect with NMS server.
OR2-SBLP2-21F receives Node-B RF signals as input via donor antenna and sends
them to ICS of digital board and Down Link amplifier where they are amplified to a
proper level to the service antenna. Also it receives mobile phone RF signals as input
via service antenna and sends them to ICS and Up Link amplifier to the donor antenna.
ICS is to cancel echo feedback signals between donor antenna and service antenna. It
consists of RF and digital parts.

2.2. NMS Network
OR2-SBLP2-21F can be operated with its own RMS (Remote Monitoring System) or
connected with the existing remote management system if the operator provides the
protocols.
The Connection between Remote management system and OR2-SBLP2-21F
follows the standard of network operators.
