Intelibs, Inc. Proprietary and Confidential Page 3 4 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. 2. 3. 4. 5. 6. 7. Quadruple-Band support by one box with small form factor Multiple Technology support Low Power consumption fed by PoE or local AC adaptor +33 dBm Down Link Tx Power (Composite power of +36dBm at Antenna port) SNMP based remote management support Single mode Fiber fed with 10 Km distance of 5dBo 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 Intelibs, Inc.

Figure 2-4 Inside of MRU Table 2-3 Modules Module Picture Description DC/DC Converter This module converts +48VDC of PoE cable into +29VDC and provide this DC power to each active module in MRU. Low Band High Power Amplifier This module amplifies low band signal such as 700/850MHz in order to get high energy and transmit high energy signal to Multiplexer filter. Composite power can be transmitted by this amplifier is 2W(33dBm/total). Intelibs, Inc. Proprietary and Confidential Page 9 10 High Band High Power Amplifier RF/Optic Module Quad Band Multiplexer This module amplifies high band signal such as 1900/2100MHz in order to get high energy and transmit high energy signal to Multiplexer filter. Composite power can be transmitted by this amplifier is 2W(33dBm/total). This module converts optic signal from RHU into DL RF signal and transfer to HPA. In case of Uplink, this module converts RF UL signal into optic signal to transfer to RHU. And this module amplifies RF signal to compensate optical loss. This module has wide band RF matching circuit to handle 4band signal. And optic wavelength of this module is 1550nm for Rx and 1310nm for Tx. This module filters 4 band(8 path) signal and cut off unwanted signal strictly. This Quad band multiplexer filter is at the front-end and cutoff unwanted out of band noise signals.
