1 System 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>

2 System 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.

Mobile WiMAX
Manual
9 / 102
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.

[Figure 4] Bottom view of MOBILE WIMAX System
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)

4.1.1 Repeater External Appearance
Repeater’ s enclosure prevents dust and other pollutant particles from entering and is
designed for wall mount positioning. Heat-sink is placed to dissipate heat.

4.1.2 REPEATER INTERIOR
Structure of the unit is simplified so that maintenance will be easily handled; therefore
the number of modules is minimized. Inside the repeater enclosure, there are 6 modules
that are laid out. These modules are Switch, PSU, HPA, BPF, UDC and Controller.

4.2 Explanation of Internal Configuration
4.2.1 Switch Module
WIMAX DPDT (Double Pole Double Throw) RF Switch LNA is applied to the
WIMAX RF repeater.
High Isolation values are used for Down Link and Up Link segregation (More
than 120dB). With low insertion loss, Noise Figure value and HPA output loss
can be lowered. When TTL sync is high, downlink path is set and when TTL
sync is low, Up Link path is set.
[Figure 7] Switch Module Feature
4.2.1.1 HPA
HPA is the input signal port for RF signals which travel out the Link and Service port.
4.2.1.2 LNA
Signals make their way into Link and Service ports, whereby weak signals are amplifie
d and exit out of LNA OUT. Signals are then delivered to up/down converter’ s input
port.
4.2.1.3 Service
Service port connects directly to BPF. Based on a switching mechanism, high

amplified signals enter into the HPA and exit its way out of the service port. The signal
then gets filtered by BPF and travels toward the service antenna. When the switch
module is in a different state, weak signals from the service antenna pass through the
BPF and into the service port. These signals exit the LNA out port to be amplified.
4.2.1.4 Link
The Link port connects directly to BPF. Based on a switching mechanism, high amplifi
ed signals enter into the HPA and exit its way out of the Link port. The signal then get
s filtered by BPF and travels toward the donor antenna. When the switch module is in
a different state, weak signals from the donor antenna pass through the BPF and into
the Link port. These signals exit the LNA out port to be amplified.

4.2.2.1 RF Module
Mobile WiMAX signal is received at the LNA (Switch Module). The signal is down
converted and passed through a SAW filter. Once any unwanted signals have been
removed, it is up converted, amplified and then sent to the HPA (Switch module).
Digital variable attenuators are built into the repeater so full gain control can be performed
for forward and reverse direction (As it handles duplex transmission).

5 Signal Block Diagram and Signal Flow
5.1 System Block Diagram
In order to minimize the size of the device, we have implemented a design that is
single pass and bi-directional serviceability.
A single pass repeater is small, simple and reduces the cost of the system. It
also generates less heat and is light weight thus installation and maintenance
becomes easy to handle. Single pass, bi-directional repeater’ s block diagram is
shown below along with other components that have been implemented such BPF
, RF Switch (DPDT), LNA, Converter and HPA Module.
[Figure 14] MOBILE WIMAX Repeater Block
5.1.1 Forward Direction Block Explanation
Signals from BTS are received via the repeater’ s donor antenna. These signals are then
filtered through the BPF (Band Pass Filter) and enter into the DPDT RF switch as inputs.
Mobile WiMAX
Manual
40 / 102
Within the DPDT switch, down link and up link paths are switched alternately. In a down
link switching state, signals are sent to LNA where low noise amplifications are applied
and sent to the Up/Down Converter. At the converter, only the relevant bands are passed t
hrough the SAW filter and forwarded to the HPA. HPA amplifies these signals to high outp
ut and passes it through to the DPDT switch and BPF. The signals finally radiate out the s
ervice antenna.
5.1.2 Reverse Direction Block Explanation
Signals from PSS (Portable Subscriber Station) are received via repeater’ s service antenn
a. These signals are then filtered through the BPF (Band Pass Filter) and enter into the DP
DT RF switch as inputs. Within the DPDT switch, down link and up link paths are switched
alternately. In an up link switching state, signals are sent to LNA where low noise amplifica
tions are applied and sent to the Up/Down Converter. At the converter, only the relevant b
ands are passed through the SAW filter and forwarded to HPA. HPA amplifies these signal
s to high output and passes it through to the DPDT switch and BPF. The signals finally rad
iate out the donor antenna.

amplifying received signals via LNA. Signals are sufficiently amplified by HPA so
that it can be emitted out towards the BTS or PSS.

6 Additional Function
6.1 ASD (AUTO SHUTDOWN) Function
6.1.1 Aim of ASD Functions
In order to protect the repeaters setup and networks stability, output must be
suppressed. This is done by activating the automatic shutdown function when
down link input is high, up link output is high or when oscillation occurs.
Shutdown function operates by following the algorithms shown in the figure below.
6.1.2 ASD Management Procedure
For Automatic Shutdown, when DL Input is high, value is shown as -14dBm/Total
and when UL Output is high, +36dBm/3FA is the value. ASD algorithm is
performed like the figure below.
