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.

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.

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

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

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.
