1. Introduction
1.1 Fiber Fed Repeater
The JF-46 FFR provides a cost effective solution for cell coverage extension and
increased call quality in shadow areas. It is a RF signal transport system that
provides long range RF coverage where it is impractical to install a BTS.
The JF-46 FFR is designed to be strategically placed to overcome difficult zoning
issues by allowing the base stations to remain at a central location while placing
antennas at remote locations. RF signals can be transported to remote locations to
expand coverage into areas not receiving service or to extend coverage into difficult
to reach areas such as canyons, tunnels and underground parking lots and roadways.
The JF-46 FFR provides a high-tech, highly-efficient service system which enables
high quality communication at low cost, due to the system’s utilization of one optical
fiber core between the DHU and RU supporting full duplex transmission of signals for
both the DL and UL.

1.2 Search Window
The purpose of using a repeater is to extend the coverage of the BTS by re-
transmitting the BTS signals to mobile stations in a non BTS coverage area. This
means that the BTS handles all kinds of call processing including calls being received
via the repeater. There may be a negative impact of service on the BTS if the
interface between BTS and repeater does not operate properly.
There would be an increase in time delay with calls received from the repeater,
compared to a call from its BTS coverage. Thus the additional delay introduced from
calls via the repeater must be considered while setting BTS parameters.
Window-size is the time range of the BTS traffic channel to search for the signal
originating from the MS. If the delayed signal is out of window-size, the BTS cannot
acquire the signal, which will result in dropped calls due to chip-delay.
Table 1.2.1 describes the two parameters used for controlling the window length, to
prevent the deterioration of call quality caused by chip delay. It is required to search
the signal properly by adjusting the two parameters.
Acquisitioin_Window_Length is adjusted to change the window size used to
search/monitor the neighboring PN and allow soft handoff while traveling to the
neighboring BTS where new traffic channels will be allocated to the MS.
Demodulation_Window_Length is adjusted to change the window size which searches
for the Rx signals. This parameter should be adjusted when the delay (with no change
of traffic channel) between transmission and reception is increased i.e. MS in repeater
service area.

Notice
Acquisition_Window_Length Demodulation_Window_Length
Window Range of BTS traffic channel
to search for time sync of other BTS
Use this parameter when traffic
channel is changed (Soft hand off)
Window Range of BTS traffic channel to
search multi path referring to the time-offset
Use this parameter when traffic channel is
not changed. (Tracking multi path signal)
Too big a Window_size causes increase of time for the mobiles to search for BTS
signal. It should be set up with proper values considering time delay.
[Table1.2.1] Two Parameters for Search Window Setup
Therefore, the two parameters stated can be used to adjust the interface between
the BTS and the repeater considering the movement of the MS. Picture 1 shows an
example of two window size parameters for the JF-46 repeater application.
[FIGURE 1.2.1] HANDOFF BETWEEN BTS AND REPEATER
The Demodulation_Window_Length is used to adjust the time sync to compensate
the chip delay introduced by the optic core when the MS moves into the repeater
coverage area.
When the MS travels from the repeater coverage to the BTS B area,
Acquisition_Window_Length is used to adjust this time offset differences. With this
adjustment, the MS will be able to perform soft handoff from BTS A traffic channel
(while in repeater coverage) to the BTS B traffic channel.
Without these adjustments, there may have been two call drops while the MS traveled
from BTS A to BTS B.

1.3 Total Optical Delay (Window Size)
With the adjustments described above, good call quality should be maintained without
call drops. This section will show how to calculate the total delay and how the
parameters should be set up in the BTS. The equation below is an example of total
delay for an optic repeater.
SD(μsec) + OD(km) + RD(μsec) + RR(km)
SD : BTS System Delay (Time delay between antenna input port and demodulator in BTS)
OD : Optic Distance between BTS and repeater.
RD : Repeater System Delay
RR : Repeater Coverage Radius
* 1 chip = around 244 m
The total chip delay of 2km of RR and 5km of OD is as below.
36chip + 5000m(20.63chip) + 5 μ sec(6.6chip) + 2000m(8.25chip) = 71.45 chips (Approx.
72chips)
Based on the calculation of total chip delay, the two parameters should be adjusted for
good call quality when installing a new repeater. 71.45 chip delay corresponds to 12
(set value) Search window size (Size = 160 chips). Therefore, the
demodulation_window_length of BTS A should be set up as 12 in this configuration
and acquisition_window_length of BTS A and BTS B should also be set up as 12.
The table below shows the Search window size values for different optic distances
and repeater coverage.

can be added to the DHU to increase service coverage. A flexible RF splitter unit
can also be implemented to combine multiple RF ports supported by newer BTS.
• The slim and sleek appearance of the RU allows it to be installed and deployed in
difficult zoning areas.
• The water and moisture resistant IP55-rated design make it reliable and durable.
• The FFR system is monitored and controlled from a central remote location by
making use of a CDMA wireless modem via the SNMP protocol.
• Operation, maintenance and repairs are simple. The system provides alarms and
information on the repeater gain settings, output level control, LPA on/off, internal
temperature monitoring and problems concerning the optic module. The system is
designed to operate with a comprehensive network management system.
• The system uses only one optical fiber core for transmission and reception of
signals. To achieve this, WDM is implemented which enables multiple wave-
lengths (DL: 1510nm, UL0: 1530nm, UL1: 1570nm) to be simultaneously
transmitted and received through the one optical fiber core.

1.7 General Safety Precautions
This equipment contains components that emit laser radiation which can
seriously damage the retina of the eye. Do not look into the ends of any
optical fiber. Do not look directly into the optical transceiver of any digital unit
or exposure to laser radiation may result. An optical power meter or
reflectometer should be used to verify active fibers. Place a protective cap or
lid immediately over any radiating transceiver or optical fiber connector to
avoid potential damage caused by radiation exposure. This practice also
prevents dirt particles entering the openings.
The optical fiber emits radiation. Do not look directly into the ends of an
optical fiber. This may result in exposure to radiation. Do not assume laser
power is turned off or the fiber is disconnected at the other end.
Wet locations and conditions will increase the risk of electrical shock when
installing or using electrical powered equipment. To prevent electrical shock,
never install or use electrical equipment in wet locations or during lightning
storms.
The DHU is powered by 115-230 VAC. To prevent electrical shock when
installing or maintaining the DHU, disconnect the wiring at the power source
before working with un-insulated wires or terminals.
The RU is typically powered by 115-230 VAC. To prevent electrical shock
when installing or maintaining the RU, disconnect the wiring at the power
source before working with un-insulated wires or terminals.
Always consider and allow sufficient fiber length to permit routing or patch
cords and pigtails without severe bends. Fiber optic patch cords or pigtails
may be permanently damaged if bent or curved to a radius of less than 2
inches (50mm).

2. System Description
2.1 FFR System
The JF-46 FFR is made up of a main Donor Hub Unit (DHU) and a RU. The DHU and
RU are divided into modules to allow easy operation and maintenance. It can operate
even in the harshest environmental conditions due to its durable IP55-rated
weatherproof enclosure.
[FIGURE 2.1.1] SYSTEM BLOCK DIAGRAM
2.2 Simulcast Operation
Please refer to Figure 2.2.1 for a system block diagram of a Simulcast FFR
configuration, where a single BTS sector provides coverage to two Remote Units. This
configuration employs two RF Splitter/Combiner units at the RF ports of the Donor
Hub Unit which relate to the two Remote Units.
On the DL path, the BTS signal is split two ways and feeds two DHU input ports.
Similarly, on the UL path, the signals from two DHU RF ports are summed and fed to
one port of the BTS.

CDMA FIBER FED REPEATER OPERATIONS MANUAL
JUNI AMERICA PROPRIETARY & CONFIDENTIAL
The JF-46 FFR has adequate RF gain margin to support a Splitter/Combiner as
shown with loss of up to 10 dB. As a result, a single BTS sector can easily feed 4 or
even 8 Remote Units. If more than 4 Remote Units are to be supported, more than
one DHU is required since a DHU can support only a maximum of 4 Optic Modules,
which drive 4 Remote Units.

2.3.2 Wireless Modem Antenna
The technical requirements for the Wireless Modem Antenna are dependent on the
specific DHU location and network coverage. If the nearest BTS with a local antenna
is nearby the DHU, a 3 dBi Gain Omni antenna should be quite adequate. The
Modem Antenna is to be connected to the modem antenna connector on the DHU.
In the event the nearest BTS with a local antenna is quite some distance from the
DHU, a directional antenna with 10 dBi Gain, aimed at the nearest BTS with the local
antenna, is the appropriate modem antenna solution.
