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 Head End Unit such as RHU or MLU 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 local AC adaptor of DIN-F connector

4. +33 dBm/band Down Link Tx Power (4-band composite power of +39dBm 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) and Auto Shut Down(ASD) function

Including RHU and MLU, Hybrid DAS is comprised of the following subsystems:

• RHU (Radio Hub Unit): Over-the-Air Interface unit between RF source and Remote Units, Convert RF

signal into optical waves.

• MLU (Main Link Unit): Wire-connected 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

As illustrated in Figure 1-1, Hybrid DAS network is comprised of RHU, FHU, MRU and SRU. Each RHU can

support up to 16 SRU’s that can cover up to 500Ksf

indoor space or 16MRU’s that can be cover up to

800Ksf
