1 Introduction
Medium power Remote Unit (MRU) is a part of the Hybrid Distributed Antenna Systems (HDAS) to
provide remote RF coverage solution from the Radio Hub Unit (RHU) fed by the RF source via OTA or
Wireline connection. MRU is built on a small form factor with a single antenna port for dual band
frequencies with the following features:
1. Quadruple-Band support by one box with small form factor
2. Multiple Technology support
3. Low Power consumption fed by PoE or local AC adaptor
4. +33 dBm Down Link Tx Power (Composite power of +36dBm at Antenna port)
5. SNMP based remote management support
6. Single mode Fiber fed with 10 Km distance of 5dBo
7. Auto Gain Control (AGC), Auto power Limit Control (ALC), Auto Shut Down (ASD) and Auto Isolation
detective Gain Control (IGC) function
Including RHU, Hybrid DAS is comprised of the following subsystems:
RHU (Radio Hub Unit): Interface unit between RF source and Remote Units, Convert RF signal into
optical waves.
FHU (Fiber Hub Unit): Fiber distribution and aggregation interface between RHU and multiple RUs.
Each FHU supports up to 4 SRU/MRUs and total up to 16 SRU/MRUs by two level FHU configurations
SRU (Small Remote Unit): Small power (23 dBm per band) remote unit
MRU (Medium Remote Unit): Medium power (33dBm per band) remote unit
RU (Remote Unit): High power (40 dBm per band) remote unit for outdoor/indoor
MU (Master Unit): Element management server
