Intelibs, Inc Proprietary and Confidential Page 6 6 1 Introduction Remote Unit for AWS band (RU-AWS) is a part of the Hybrid Distributed Antenna Systems (HDAS) to provide remote RF coverage solution from the Master Hub Unit (MHU) fed by the RF source via wireline connection. RU-AWS is built on a small form factor with two antenna ports for 2100MHz AWS frequencies with the following features: • 10W + 10W dual band or MIMO radio for 2100MHz AWS • Multi-Technology support • 40 dBm Tx Power per band • NEMA level 4 with IPX-6 • SNMP based remote management support • Single mode Fiber fed with 10 Km distance • Optic fiber sharing between different carriers • AGC (Auto Gain Control) function • CFR (Crest Factor Reduction ) function Including RU-AWS, Hybrid DAS is comprised of the following subsystems: • MHU (Master Hub Unit): Interface unit between RF source and Remote Units, Convert RF signal to optical waves. • 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 MHU and RU. Each MHU can support up to 6 RU’s that can cover up to 500Ksf2 indoor space. An optic cable can be shared between different carriers by cascading optic connection between MHU systems.

Intelibs, Inc Proprietary and Confidential Page 8 8 2 Product Description Remote Unit for AWS is a part of the Distributed Antenna System (DAS) to clear RF shadows, to fill coverage gaps existing among the adjacent cells and to enhance the quality of service of extending coverage of 2100M AWS. As shown in Figure 2-1, RU is a compact platform with the natural heat convection. As unified form factor, RU services multiple technologies on a single platform with 2100MHz AWS band operating frequencies. It can be mounted on the wall or 19” rack. Variety of the service antenna can be used from short monopole antenna (e.g. rubber ducky antenna) to indoor multi-band ceiling Omni antenna (or panel antenna). Figure 2-1 RU system 2.1 Network configuration RF signal from a carrier on the 2100MHz AWS band are fed to MHU and directed to fiber optic cable, to transmit RF signals to remote RU system. MHU can have up to 6 connections with RU systems by installing DOU cards. A fiber optic cable can be shared between different carriers by cascading optic connection between MHU systems. Each frequency band signals have their own wavelengths in a single fiber. Table 2-1 describes those wavelength assignments. Maximum allowed optic loss between MHU and RU system is 10 dBo.

Do not compromise the amount of airflow required for safe operation of the equipment. • Verify the power connection and Fiber cables prior to turning on the systems. WARNING: Equipment loading must be verified prior to mounting the equipment on the wall or 19” rack. 3.1.1 General Safety Precautions The following precautions apply to the RU: • The units have no user-serviceable parts. Faulty or failed units are fully replaceable through Intelibs. • When the Fiber cable is connected to the equipment, the connectors must be free from the dust and connected according to the cable manufacturer’s instructions. (WARNING: For the safety, DO NOT conduct eye-contact at the connector ends of the fibers or the port of the MHU and RU unless equipped with protection goggle. Invisible infrared radiation may be present at the front panel of the MHU and RU. Do not remove the fiber port dust caps unless the port is going to be used. Do not stare directly into a fiber port.)

Intelibs, Inc Proprietary and Confidential Page 25 25 • Connect USB cable to manage RU through Laptop. Step 2 • Run LMT application as the procedure described in 2.8.1.1. Step 3 • Adjust parameters as follows: ① Decrease the DL “USER ATT” to 30dB(Minimum gain) and verify that antenna is connected at antenna port of RU properly. ② Press the “HPA On/Off” button to turn HPA on. ③ Monitor the output power level from “ OUT PWR” parameter, and tune up “USR ATT” to set the proper output power level.
Intelibs, Inc Proprietary and Confidential Page 26 26 3.8.2 Up Link power setting • Follow same steps as Downlink power setting. Step 1 – Step 2 • Run LMT application as the procedure described in 2.8.1.1. Step 3 • Adjust parameters as follows: ① Use the “ATT” to control Uplink gain. ② Uplink gain is very important parameter because uplink is connected to RF source of BTS. If you have wrong uplink gain set, BTS receiver sensitivity may be degraded due to improper uplink gain. ③ Try to minimize uplink gain with mobile Tx power. ❶❷❸
Intelibs, Inc Proprietary and Confidential Page 27 27 4 Configuration and Maintenance RU can be configured in three ways via remote internet connection or local serial port connection. • SNMPv3 interface through the internet • Web interface through the internet • Local management interface through the internet, serial connection, and Bluetooth Master Unit is a remote management system that provides SNMP v3 and Web interface, and maintains all functions of optical DAS system including configurations, monitoring, and real time alarm reporting. LMT (Local Management Terminal) is local management interface through IP network, serial interface, and Bluetooth.

Following is one example of Web operation which sets the upper limit of RU chassis’ temperature.
Intelibs, Inc Proprietary and Confidential Page 38 38 • Open Web browser such as Internet Explorer or Chrome. Step 1 • Enter Master Unit’s IP address that is assigned for Web interface. Usually the IP address is global IP or private IP if web client is on the same network where Master Unit is. • Enter Login ID and Password. (Please contact Intelibs for login ID and password) Step 2 The web interface provides two level user access, privileged or not. Privileged users can retrieve and change the advanced parameters that control the DAS system. For example, “TMPUPR” parameter is an advanced parameter that requires privileged user login. • If ID/PWD matches, Web interface goes to Home page.
