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.
Figure 2-2 Typical MHU-RU network diagram 2.2 External interface ports RU has all interface connections at front side of an enclosure, which includes optic, antennas, power, and maintenance port. Figure 2-3 shows the front panel of RU system.

2.3 Modules RU system is comprised of several internal modules such as combiner, amplifier, optic module, and filters. Figure 2-4 shows inside of RU system.
RRBS1_AWS Amplifies RX1 signal by low noise high gain amplifier, filters for desired band frequencies, and controls uplink path gain. HPA_AWS for MIMO0 Amplifies TX0 signal by 16W (42dBm) high power amplifier, and sends amplified signal to FE_DUPLEXER_AWS MIMO0 module. HPA_AWS for MIMO1 Amplifies TX1 signal by 16W (42dBm) high power amplifier, and sends amplified signal to FE_DUPLEXER_AWS MIMO1 module. FE_DUPLEXER_AWS for MIMO0 Front-end duplex that passes TX0 and RX0 frequencies bands.

3.4 Mounting RU supports wall mount. The following diagrams illustrate the methods for mounting RU on a typical wall. Step 1 • • Mark the upper position by using the wall mount bracket for upper position. Mark the lower position by using the wall mount bracket for lower position. 327 mm (12.87”) 327 mm (12.87”) 332 mm (13.07”) Figure 3-1 Mark the installation position Step 2 • Screw two bolts to the upper positions.
Step 3 • Install the wall mount brackets as figure below. The wall mount brackets and the bolts are provided along with RU system. Mounting bracket RU with bracket Figure 3-3 Install the wall mount bracket Step 3 • Insert upper bracket hole into installed bolts on the upper positions.
Interface ports on the bottom Interface ports on the top Figure 3-4 Hanging the upper bracket on the installed bolt Step 4 • Screw two bolts to the lower positions.
Interface ports on the bottom Interface ports on the top Figure 3-5 Install the lower bolts 3.5 Link (Donor) Antenna RU has two antenna ports. The one is for Cellular/LTE-main/AWS-main channel, the other is for PCS/LTEMIMO/ASW-MIMO channel. Connect N-type female antenna cable to the desired antenna port, “ANT-0” or “ANT-1”, as Figure below.
The duplex can be used which combine two port signals into one. AWS Main AWS MIMO Duplex Figure 3-7 Link Antenna connection with Duplex 3.6 Power cable Connect MS connector-type power cable to the “AC-INPUT” port. When connecting the end terminal, align connector at latch and hole position as marked in red circle in Figure below. Figure 3-8 Power cable connection 3.7 Optic cable RU provides two optic ports. The one is for main channel, the other is for cascading purpose.
Figure 3-9 OSP hardened SC/APC optic cable Connect ruggedized OSP side optic connector to the desired optic port on RU, “OPTIC-A” as Figure below. When connecting the optic connector, align the connector at latch position, then plug in and rotate clockwise tightly. Figure 3-10 Optic cable connection 3.8 RF power setting 3.8.1 Down Link power setting Step 1 • Connect the power cable to RU to turn on the system.
Step 2 • Connect USB cable to manage RU through Laptop. Step 3 • • Run LMT application as the procedure described in 2.8.1.1. 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.
❶ ❷ ❸ 3.8.2 Up Link power setting Step 1 – Step 2 • Follow same steps as Downlink power setting. Step 3 • • Run LMT application as the procedure described in 2.8.1.1. 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.
❶ 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.

4.1 Configuring RU using LMT If one of serial or LAN connection has been established, LMT is ready to start. Launch the Local Management application by clicking the icon “Cherry” and follows the steps below. Step 1 • • • Launch the application “Cherry”. Enter the password, click “Login”. Click “Connect” icon on the left top corner of window or click [File]-[connect] menu.
Step 3 • If “Repeater Browser” window appears, click MHU-LTE system. Step 4 • Click any place inside of “Install” panel area. Step 5 • • At “Install / Uninstall RU – [MHU-LTE]” window, click the RU systems that has been installed according to MHU’s port number that is connected via optic cable. Then click “Set” button.
Step 6 • • If RU is installed properly, the RU system can be found under the MHU system in “Repeater Browser” window. At “Repeater Browser” window, click the DAS system to be managed, then the selected DAS system’s control window will pop up. If connection is established successfully, then all parameters of RU system can be read/set by LMT terminal, and all status information can be reported to LMT. RU’s status and parameters controllable by LMT are described in Table 4-2, 4-3, 4-4, and 4-5.

4.2 Example: Setting the Temperature Upper Limit Following is one example of LMT operation which sets the upper limit of RU chassis’ temperature. Step 1 • • At “Repeater Browser” window, click the DAS system to be managed, then the selected DAS system’s control window will pop up. Click the temperature upper limit box which is on the right side of “TMPUPR”. A number in the box represents current upper limit of chassis’ temperature.
• Click close button on the upper right corner of the window to exit the command window. The small color box on the left side of “TMPUPR” represents current status of upper limit of RU chassis’ temperature. If the box is GREEN, operating status is in normal condition. If the box is RED, “TMPUPR” alarm occurred and remains. 4.3 Web interface Master Unit provides comprehensive management of the Intelibs optical DAS systems via Web GUI.
The menu panel contains following menu functions: • • • • • • • • • • Home: Introductions of Intelibs, Inc, and brief introduction of GUI usage. DAS systems: Hierarchical view of registered DAS systems. Alarm history: Alarm log of all registered DAS systems. Alarms: Current alarms of all registered DAS systems. SNMP settings: SNMP environment settings such as trap IP, community, V3 user, etc. Site settings: Assign site and location information to each registered Das systems.
Step 1 • • Open Web browser such as Internet Explorer or Chrome. 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. Step 2 • Enter Login ID and Password. (Please contact Intelibs for login ID and password) 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.
Step 3 • Click “DAS systems” menu box to see the Hierarchy view of DAS systems.
Step 4 • Select a DAS system to control and monitor at the hierarchy view. Step 5 • Select “Advanced Mode” check box to display advanced parameters, for example “Chassis High Temperature Alarm Threshold” in the parameter view panel.
Step 6 • Enter numbers for “Chassis High Temperature Alarm Threshold”. Then click “Set” button. Step 7 • If confirmation window pops up, click “OK” button to confirm changing the parameter value. • Then result window will pop up. The column “Chassis High Temperature Alarm” represents upper limit of RU chassis’ temperature. If the value box is GREEN, operating status is in normal condition. If the box is ORANGE, this indicates “TMPUPR” alarm is turned on.
