1 Introduction
Small Remote Unit (SRU) is 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 wireline connection. SRU is
built on a small form factor with a single antenna port for dual band frequencies with the following
features:
• Multi-Technology support
• Low Power consumption fed by PoE or local AC adaptor
• 23 dBm + 23 dBm Tx Power per band
• Easy antenna installation
• SNMP based remote management support
• Single mode Fiber fed with 10 Km distance
• Auto Gain Control
• Band and Sub-channel filtering using DSP
Including SRU, Hybrid DAS is comprised of the following subsystems:
• RHU (Radio Hub Unit): Interface unit between RF source and Remote Units, Convert RF signal to
optical waves.
• FHU (Fiber Hub Unit): Fiber distribution and aggregation interface between RHU and multiple SRUs.
Each FHU supports up to 8 SRU and total up to 32 SRUs by two level FHU configurations
• SRU (Small Remote Unit): Small power (23 dBm per band, 26 dBm in dual 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 and SRU. Each RHU can
support up to 16 pair of SRU’s that can cover up to 500Ksf
