3 Safety Precautions Opening the WiMAX equipment could result in electric shock and may cause severe injury. Connect the equipment frame ground to the building ground. Operating the WiMAX with antennas in very close proximity facing each other can lead to severe damage to the repeater. RF EXPOSURE INFORMATION A minimum separation distance of 7.9 inches (20cm) must be maintained between the user and the external antenna of the repeater to satisfy FCC RF exposure requirements. For more information about RF exposure, please visit the FCC website at www.fcc.gov This equipment is for indoor use only and enables the communication wiring to communicate inside the building.

5 Glossary The following is a list of abbreviations and terms used in this manual. Abbreviation Definition AC Alternating Current ANT Antenna ATT Attenuator / Attenuation WiMAX Worldwide Interoperability for Microwave Access DC Direct Current DL Downlink GND Grounding GUI Graphic User Interface LED Light Emitting Diode PLL Phase-locked loop PSU Power Supply Unit RF Radio Frequency RSSI Received Signal Strength Indication TEMP Temperature TTG/RTG Transmit/Receive and Receive/Transmit Transition Gaps UL Uplink VSWR Voltage Standing Wave Ratio ALC (Automatic Level Control) ALC feature prevents the repeater from exceeding its maximum output power by reducing the gain automatically. ALC is used to adjust the gain to an appropriate level for a range of input signal levels. ASD (Automatic Shutdown) Automatic shut down protects the repeater from the oscillation or excessive input signal and eliminates any degradation to the network. There are three parameters: ASD Level, ASD Time, and ASD Iteration. If the output power gets higher than “ASD LEVEL”, the repeater will shut down for “ASD TIME” seconds and then it will turn the amp back on to measure the output power again. If this repeats at “Iteration” times, the repeater will shut down completely.
6 1. Introduction WiMAX repeaters are used to fill out areas in the WiMAX mobile systems, such as base station fringe areas, business and industrial buildings, etc. WiMAX repeaters receive signals from a base station, amplify and retransmit the signals to the mobile stations. It also receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously with the following features A. RSN-WiMAX-23 ◆ Band Select >> designated low and high segment Bandwidth [Low: AB, BC, CD / High: EF, FH, HG] ◆ Easy and Quick Installation >> Web-based GUI >> Plug and Play – DHCP Server @ Local Port an DHCP Client >> Easy Setup(Automatic) >> Real Time Isolation Detection ◆ Auto Level Control & Auto Shut Down - This repeater allows the Web Server and Web GUI to communicate with a PC, except for the function of reporting through the radio network. There is only one physical RJ-45 port: • The local port provides an on-site access to the repeater. - DHCP server at the local port enables Plug and Play by automatically assigning the IP address to the user’s computer - Parameter setup is only a Power ON away • Main features of Easy Setup is to set up the output power level along the each time segment of DL/UL path gain after receiving a sync signal from an input signal. Until it is synchronized, it does not progress to the next step where it will measure the isolation and limit the maximum gain accordingly. This will also enable Auto Level Control as well as Auto Shut Down. These two features are strongly recommended to prevent uncontrolled power output, which could have an adverse impact on the RF network and the repeater. For example, ALC will automatically apply attenuation when the input signal strength is increased due to the new base station deployment near the repeater site

27 Solution 1. Easy setup [Recommended] Step 1 Select the operating Band and click APPLY. Step 2 Easy Setup Easy Setup proceeds to: ∙ Data initial execution ∙ Sync signal acquisition ∙ HPA ON ∙ ALC gain set ∙ ASD ON ∙ ALC ON to obtain Maximum DL Output Power 23dBm[Default] or Maximum Gain 80dB. ∙ Real time isolation check Click Automatic Easy Setup. Easy Setup feature detects Sync signals from the input RF signal. If the Easy Setup processor does not receive a sync signal, it does not progress any further and performs the sync signal acquisition step.
28 Step3 Click OK Step 4 Setup will automatically begin. This process takes approximately 1 minute. Result 1 Constant Maximum DL Output Power 23dBm If the DL Input Power >= -57dBm
29 Result 2 Maximum Gain 95dB if the DL Input Power < -57dBm ∙ Automatic Level Control: Type under 23 and then click APPLY and ON. This is an example case for a repeater with 23dBm maximum output power, 80dB maximum gain/35dB gain control range, Æ If the signal -47dBm and the ALC is set as 23dBm, the gain will be 70dB to adjust to the output power. If the input signal is -60dBm, the output power will be 20dBm by the limitation of the maximum gain even though the ALC is set as 23dBm
30 ∙ Automatic Shutdown: Type the desired value for dBm, seconds, and times and then Click APPLY and ON. [Example] A repeater with 23dBm Maximum Output Power, 80dB Maximum Gain/35dB gain control range, assuming ASD Level: 25dBm, ASD Time, ASD Count are already fixed at 3seconds, 10times. If the composite output power is 25dBm(ASD Level) and higher, the repeater will shutdown for 3seconds(ASD Time). If the shutdown occurs 10times(ASD Count), the 11th shutdown will be permanent. The repeater automatically runs Easy Setup. After that, it is activated with the re-calculated antenna isolation value.
31 Solution 2. DL Output Power < Max. 23dBm Step 1A Repeat Step 1 through Step 4 Step 2A Change the level at Automatic Level Control and then APPLY Result Constant output power set as the ALC Level
32 Solution 3. Manual Gain Setting Gain [Not Recommended] Step 1B Repeat Setps1 through 4 Step 2B Read the DL Input Power and the gain controlled by the Easy Setup. Step 3B Turn off HPA Step 4B ALC must be turned off
33 Step 5B Change the DL gain and the UL gain Step 6B Turn on HPA Result DL and UL gain are fixed and the output power depends on the input power.
34 Alarms <Alarm Status> <Alarm Range> ∙ Alarm : If an alarm occurs, the alarm LED on the repeater will turn on. Please refer to the troubleshooting section of this manual. ∙ No Change in values on the alarm range is recommended.
35 5. Troubleshooting Before contacting your service dealer, please make sure you refer to the following guide. If the WiMAX repeater does not work normally after completing the following troubleshooting, please contact your local dealer or R-tron America’s Tech support line (888-31R-TRON). The alarm information is displayed by the LED lights on the repeater. Problem Cause Solution No LED on Check the power cord for secure connection. Alarm LED On In/output power alarm occur and lost a sync signal Over input, Over Output, out of sync; In case of these 3, the alarm LED is on, If the alarm is by over input or over output, the ASD algorithm is applied. If the RF environment is normal, the LED is automatically turned OFF. For Out of sync, it searches the sync for up to 1 hour when the synch is lost. After that, HPF is turned OFF. If it still searching for the sync. At this moment, the status of TDD S/W maintains DL. If the sync is obtained again, HPA is back ON and the ALARM LED is turned OFF. Alarm LED flickering Occurs at the lowest limit of output When the alarm occurs by low input and not by the isolation ATT, it is flashing. When the output power comes back to normal, the LED is turned OFF. When the WiMAX’s selected band is different from the actual service band, service is impossible.
