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
