1. Introduction
1.1. General Introduction
As an equipment to clear RF shadows inevitably generated between the adjacent cells of
LTE, LMR250R01C supports LTE and effectively repeats the signals between mobile
terminals in weak coverage area and BTS.
This equipment is LTE MIMO Optical DAS that support 700MHz band simultaneously,
and it is designed to support LTE with MIMO.
This equipment provides the cost effective and flexible wireless solution to service
providers to improve quality of service for their subscribers.
The main objectives of LMR250R01C are as follows:
- Expansion of coverage
- Enhancement of service quality in areas such as tunnels or in-building
- Improvement in signal strength at places where the signal level is less than desired.
- Support dual bands of 700MHz.
- Support single mode of LTE band.
- RU power consumption and RU size optimization by built-in Crest Factor Reduction
(CFR) technology for the LTE signal.
2. System Network Configuration
2.1. Network configuration
LMR250R01C repeater is equipment to clear RF shadows, to fill coverage gaps existing
among the adjacent cells and to enhance the quality of service by extending coverage of
LTE.
The network configuration of LMR250R01C is the case that 1 MHU is connected with 1
RU by optical cables, and the coverage antennas of 700MHz are connected to RU, and
the link antennas of each band are connected to MHU.
 System configuration
 MHU Capacity: 1 Optical Branch/MHU
 System Connection: single-mode Optical cable between MHU and RU
 Optic Wavelength: 1570nm for FWD, 1330nm for RVS
 Max loss of optic cable (between MHU and RU): 2 ~ 10dBo
 2 coverage ANT ports for MIMO on RU. (Separate ANT Ports for 700MHz)
