1System Outline
Mobile WiMAX operates at 2.5GHz frequency band and it offers wireless internet
service at medium to low velocity movement without connection being cutoff.
Mobile WiMAX guarantees mobility and due to inexpensive wireless internet access,
it has become a necessary technology. Generally wireless infrastructures for radio
waves are not serviceable in locations such as in-buildings, islands, mountain
areas and shadow zones. To solve this problem, a repeater system is utilized. This
mobile internet RF repeater system is an OFDMA mobile internet system that allows
services in in-buildings such as offices, underground parking areas, shopping malls,
sub-station locations and small scale areas. This system can provide coverage to
shadow zones where radio waves can’ t penetrate. Some of these locations may
be underground or indoor areas with dense traffic.
<Shadow Zones>
- Underground: subway, underground shopping mall, underground passage,
underground car park, etc.
- Terrestrial: inside large building, tunnel, dense city centers, etc
<In-Building Application> <Subway Application>
<Tunnel Application>

2System Configuration
2.1 Mobile WiMAX
This mobile WiMAX system was developed so that signals could be retransmitted to
shadow zones and thus provide service to these areas. Setup for this unit has become
very common in indoor areas such as underground shadow zones.
Donor antenna and service antenna ports for the repeaters are configured to N-
females while monitoring ports for repeaters are configured to SMA female.
In order for operator’ s to easily understand the repeaters operational status,
Ethernet port is used so that units can be monitored and allow repairs to be easily
made.
For 33dBm repeater: Maximum value of 33dBm/Total can be emitted for forward
and reverse direction.

2.1.1 Base Station Direction (Donor ANT)
Connect the antenna cables to the donor antenna port which is located on the
top section of the repeater. The donor antenna is installed outside on the
building so that it will be able to receive signals from base station.
[Figure 3] Top view of MOBILE WIMAX System
2.1.2 Service Direction (Service ANT)
The service antenna port which is located at the top section of the repeater
is connected to the service antenna cable. These antennas that are
connected to the repeaters are able to provide service to the Shadow Zone
and allow for a satisfactory smooth signal. So, in order to match site
characteristics with an installation location, an antenna type has to be
determined and connected.
2.1.3 UL CPL (Up Link Coupling)
Up link coupling is for operators to analyze the status of an Up Link path. It
is a port for measuring UL signal waveform and strength.

2.1.4 DL CPL (Down Link Coupling)
Down link coupling is for operators to analyze the status of a Down Link
path. It is a port for measuring DL signal waveform and strength.
2.1.5 GUI
Communication is made between repeaters and the PC operation program
via an RJ-45. The GUI confirms that the conditions of the repeater and
status settings are made on the ports.
2.1.6 AC Power
Repeater’ s operational power supply is connected via an AC cable.
2.1.7 DC Battery
When the AC power supply is cutoff, DC +24V battery is implemented as the
back up power source. (Option)
