2. FUNCTIONAL DESCRIPTION
2.1 GENERAL
This repeater is designed to help improve communications signal and coverage by
extending the coverage of a base station. The outdoor Donor (Base) antenna receives
the signal from a base station and conveys it to the Digital Repeater. The Repeater
amplifies the signal.
After amplification, the signal is passed through to the Mobile antennas, either
outdoor or indoor. Conversely, signals from handsets are amplified and retransmitted
by the Repeater to the base station.
2.2 FUNCTIONAL DESCRIPTION
The incoming signal processing in the Digital Repeater is processed similarly for both
the Uplink and Downlink paths.
Figure 1 provides a functional block diagram of the Digital Repeater.
Figure 1: Digital Repeater - Block Diagram
The incoming RF signal from either the Base antenna (from the BTS) or from the
Mobile antenna (from the mobile handset) enters the Repeater and is first filtered by
the Duplexer. The incoming signal is amplified by an Automatic Gain Control (AGC)
amplifier, then down-converted.
The input RF signal is then sampled and converted into a digital signal. This digital
signal is filtered using fast parallel logic. The Repeater generates up to eight
separate, programmable, and independent filters using digital processing techniques.
These programmable filters sort the digital signal.

Pub. 302-2004 Rev. 2.0
DEKOLINK WIRELESS LTD.
PRODUCT MANUAL
DIGITAL REPEATER
After filtration, the digital signals are converted back into analog signals and
up-converted to RF signals by the Up-Converter.
The output RF signal is then amplified by a High Power Amplifier, and combined by
a duplexer before output.
The output signal is emitted by the antennas, either towards the BTS in case of a
signal from the mobile handset, or to the Outdoor antenna or to the Indoor antennas
array, in accordance with the application.

3.2 COMPONENTS GENERAL DESCRIPTION
A description of the main components of the Digital Repeater follows.
3.2.1 Channeler
The Channeler Module consists of the dual Radio Frequency (RF) Up/Down
Converter sub-modules for Downlink and Uplink paths.
The Channeler amplifies the input RF signals and converts them into an intermediate
frequency (IF). The IF outputs of the Channeler are routed to the Dekolink Digital
Filter (DDF) modules.
In the DDF, the IF inputs from the Channeler are converted back to their original
frequencies. The Channeler also includes digital controllable attenuators (range 32
dB, in steps of 1 dB) and a pre-amplifier for each path.
3.2.2 Monitor Module
The Monitor Module monitors the Repeater operation and provides a visual warning
whenever it detects a failed module or function. The monitoring is performed by
measuring the current of several elements:
• DDF Uplink and Downlink,
• Up/Down Converter,
• Uplink Power Amplifier, and
• Power Supply.
If a module fails, the appropriate red LED lights up and a report is forwarded to the
Control Box.
For a more detailed description of the module, refer to paragraph 3.3.
3.2.3 Controller
The Controller (also called Control Box) controls and monitors the parameters in all
modules of the Repeater. It provides local or remote connection to a PC (See
Dekolink’s RMT User's Guide for more information.).
For a more detailed description of the module, refer to paragraph 3.3.
3.2.4 Digital Filter Module
Dekolink’s Digital Filter Module uses digital processing techniques to generate up to
eight separate, programmable, and independent filters. These filters are activated in
both the Downlink and the Uplink paths.
The filter parameters can be modified and tailored to meet the customer’s specific
applications requirements.
3.2.5 Connections Box
The Connections Box module interconnects the Repeater Modules. This box includes
the Repeater ON/OFF switch and the power fuses.

4.4 RF EXPOSURE WARNING
4.4.1 General
In order to satisfy the FCC RF exposure requirements, it must be ensured that the
installation complies with the following requirements.
4.4.2 Donor Antenna requirements
The Donor antenna connected to the BASE port in the Repeater is usually installed
outdoor. This antenna has a very sharp beam (Yagi type or similar) pointed to the
BTS This type of antenna has 12-20 dBi gain. Cable and jumper loss is at least 2dB.
The Donor antenna must be installed to provide a minimum separation distance of
1 m from any personnel within the area.
4.4.3 Mobile Antenna requirements
The second antenna is connected to the MOBILE port in the Repeater. This interface
serves either an Outdoor antenna or an Indoor antennas array, in accordance with the
application.
In case of Outdoor application, the antenna type is omnidirectional (isotropic)
with 0 to 2 dBi typical gain, or wide beam with up to 10 dBi gain. This antenna is
installed on a mast to cover a shadowed outdoor area. Cable and jumper loss is at
least 2dB. Installation of this antenna must provide a minimum separation distance of
1 m from any personnel within the area.
In case of Indoor coverage, the output power is split into several, omni directional
antenna with 0 to 2 dBi typical gain, and distributed to different indoor areas (in
building floors, tunnels, basements, parking lots, shopping centers etc.). At least 5
such antennas must be connected to the Repeater with cables and splitters. In this
application, the maximum EIRP from each antenna shall not exceed 3W.
Consequently, the minimum required separation distance from any personnel within
the area is 20 cm. Less separation is needed if the power is divided into more than 5
antennas covering many floors or areas.

6. OPERATION
6.1 GENERAL
Carry out the following steps to operate the repeater (Refer to the RMT User's Guide
for additional information.)
6.1.1 Initial Setup
Perform the following procedures (if not yet performed):
Note
The following are further described in the Deployment and
Installation Manual.
• Measure the isolation between the antennas
• Measure the power of the chosen channels in the donor antenna field (Use
external test equipment for this action.)
• Install the unit in the field
• Connect the antenna cables to the Repeater's BASE and MOBILE
connectors
• Connect the AC power cable to the AC connector
Note
After the AC power is connected to the repeater, the Power Supply, and the fans
start operating in the Repeater. Please note that the Repeater does not start
operating until the ON/OFF switch located on the
Connections Box is set to ON).
• Turn on the Repeater (The ON/OFF switch is located on the Connections
Box).
• Connect a PC/laptop to the Repeater’s Controller with a serial cable for
local connection (Refer to the RMT User's Guide for details).
• For Remote connection instructions, please refer to Appendix D.
6.1.2 RMT Software – Setting Procedures
Using the RMT software, perform the following procedures:
• Mute the downlink and uplink amplifiers so that they do not interfere with
the frequency spectrum.
• Set the maximum transmitted power for Downlink and Uplink(Max Power)
according to the actual onsite requirements
• Set the Max Gain according to the measured/calculated input power.
Dekolink recommends setting the Maximum Gain value to approximately
18 dB less than the isolation between the antennas/
If you use SALC, there is no need to measure or calculate the gain in
accordance with the required output power because it is adjusted
automatically to attain the selected power. (For more information, see
section 9.4, Smart-ALC Function).

PRODUCT MANUAL
DIGITAL REPEATER
• Click the Digital Filters Application button in the Repeater Interface screen
• Select Tools / Read Filters in the Menu bar
• Click Yes in the dialog box. The current digital filter configuration in the
Repeater is displayed
• Set the filter configuration (number of filters, frequencies and filters type) in
the Downlink page
• Activate the relevant channels by clicking √ in the On/Off checkbox
• Select the Uplink tab and set the digital filter configuration accordingly.
After defining the digital filters (Downlink and Uplink), download the new data to the
repeater so that the information can go into effect.
6.1.3 Saving the Settings
Two ways to save the settings into the repeater are available:
• Download to RAM for temporary setting, and
• Burn-in to Flash for permanent setting.
To savethe settings:
• Click Download to RAM.
This technique is recommended for trials, tests and preliminary setup of the
digital repeater until the final configuration of the digital filters is achieved.
You can download the settings an unlimited number of times using
Download to RAM.
This process is however volatile and the information will be lost in the event
of a power failure. The DDF parameters are kept in a volatile memory only,
and should be burned to a Flash memory at finalization of the process.
• Click the Burn-in to Flash button to download the data to a non-volatile
(FLASH) memory.
You can download the data to the Flash memory a relatively large but
limited number of times (several hundreds). It is recommended to burn the
data into the Flash memory only, after you are satisfied with the filter
settings for the required application and intend to use it for long period of
time.
To finalize the procedure:
• Disable the Mute for the downlink and uplink amplifier and test the
performance in the coverage area. (Mute is the output power on/off control,
which can be set via “P.Amp On” checkbox.)
• Save the configuration files of the digital filters by selecting
File / Save configuration in the Digital Filter Application and assigning a
appropriate name to the file. This data is not saved in the RMT Database.

6.2 SMART-ALC FUNCTION
6.2.1 SALC Description
The Smart Automatic Level Control (Smart-ALC) is an innovative solution for
automatic repeater gain adjustment. Combined with advanced control algorithms,
SALC can perform gradual learning of traffic load characteristics and adjust the
Repeater Gain to the desired value.
This automatic operation practically removes the need to make initial settings for
maximal traffic load conditions and eliminates the need for numerous site visits to
take care of Gain adjustment.
SALC also reduces isolation problems and Sync amplification, and maintains
Uplink/Downlink balance.
6.2.2 ALC Function
The Repeater includes the Automatic Level Control (ALC) function on both the
Uplink and Downlink power amplifiers to prevent the saturation of the amplifier.
The amplifier includes a directional coupler and a detector that monitor the output
power. The ALC mechanism samples the output power, and decouples and rectifies
it. The ALC mechanism sends a feedback signal to a voltage variable attenuator
(VVA) that, whenever a high input signal is received, attenuates the signal level so
that the output power of the amplifier does not exceed the preset limit.
This level control ensures that the power amplifier operation stays within the linear
region only, thus preventing saturation and signal distortion.
The ALC protects the amplifiers from overloading and prevents the system from
generating spurious emissions. ALC limits the output power to a constant value
(Maximum output power). The ALC is factory preset to ON state.
6.2.3 RF Gain Setting
The gain range is 59-90 dB. The RF Gain is set separately for Uplink and Downlink.
The gain range should be set via the RMT in accordance with the input signal power
at the Donor antenna, and in accordance with the required Downlink output power.
The gain range is set using the Max Gain function (beware not to exceed isolation
limits, see note below).
The Uplink Gain is set by the Gain Delta field (that is the difference between the
Downlink Gain and the Uplink Gain) in accordance with the system needs. Note that
usually this field is set to “0” for system transparency. Please refer to Installation
Manual.
Note
It is recommended to set the Downlink path gain to a maximum of 18 dB below the
isolation between the Base antenna and the Mobile antenna.

Uplink and Downlink Alarms
A list of Uplink and Downlink alarms is provided below.
Power Amplifier
Uplink Forward Power Amplifier Current Alarm: This alarm is triggered when
the Power Amplifier current is outside of its specified limits.
Downlink Threshold Forward Output Power Alarm: This alarm is triggered
when the Power Amplifier output is lower than the specified limits.
Channeler
This alarm is triggered when the Channeler current is outside of its specified limits.
Channeler Lock-Detect
This alarm is triggered when the Channeler synthesizers are unlocked.
DDF Current
This alarm is triggered when the DDF current (including the internal fan) is outside of
the specified limits.
Voltage Standing Wave Ratio (VSWR)
This alarm is triggered when the return loss of the Downlink antenna or cable
connection exceeds 6 dB (VSWR 3:1).
The VSWR module measures the voltage standing wave ratio of the Downlink output
antenna port. If the VSWR falls below 13 dB, an alarm is triggered.
This alarm provides an indication of the status of the cable connected to the antenna.
If a cable is defective, the VSWR is decreased and the alarm is triggered again. The
alarm can be forwarded to the RMT so that faults and irregularities can be recognized
and eliminated rapidly.
DDF Communication
DDF communication is triggered when the Repeater Controller fails to communicate
with the DDF unit. The communication with digital repeater components is made via
the Control Box. If the Controller fails to read/update parameters with the Digital
Filter module, it triggers the communication alarms.
Measurements
Temperature Measurements: Measures ambient temperature of the digital repeater
chassis. A temperature sensor is placed on the heat sink and provides analog voltage
to the Control Box. The controller processes the input with a formula and provides
the measured temperature.
Downlink Forward Power Measurements: Measures the output power of the
Downlink (if the output power is less than 30 dBm, 30 dBm is displayed.) This
module measures the composite output power in the downlink output path of the
repeater.
Output Power Alarms
If the output power falls below a certain level, an alarm is triggered. You can set the
power level and the mask for the alarm. (See the RMT User's Guide for more
information.) This feature provides you with the output power of the repeater and
thereby achieves optimum output power.

APPENDIX E: DEKOLINK WIRELESS LIMITED
WARRANTY
Dekolink Wireless [Ltd.] (“Dekolink”), manufacturer of this product (the “Product”)
warrants to the original purchaser (“Purchaser”) that the Product is free from defects
in materials and workmanship for a term that ends on the earlier of twelve (12)
months from the date of activation of the Product or fifteen (15) months from the date
of shipment of the Product by Dekolink. The obligations of Dekolink under this
warranty shall be limited solely to the repair or exchange or giving credit for, at the
option of Dekolink, any Product that may prove defective in accordance with
evidence satisfactory to Dekolink. Any repair or replacement of the Product by
Dekolink shall not extend the original warranty period. This warranty is exclusive to
the original Purchaser and is not assignable.
This warranty applies only upon the condition that the Product has been installed,
maintained and operated under conditions of normal use. The provisions of this
warranty shall not apply if, in Dekolink’s judgment, the Product has been subject to
misuse or neglect, damaged in an accident or by act of vandalism, or repaired or
altered in any way that adversely affects its performance or reliability.
To obtain warranty service, Purchaser may, upon the prior written authorization of
Dekolink or its authorized service representative, return the defective Product to
Dekolink’s authorized service center. All shipping and insurance charges are the sole
responsibility of Purchaser and are not included in this warranty.
Dekolink expressly excludes and disclaims all other warranties, including but not
limited to any warranties of merchantability or fitness for a particular purpose.
Dekolink shall in no event be liable for any special, indirect, incidental, consequential
or punitive damages or for loss, damage, or expense, including loss of use, profits,
revenue, or goodwill, directly or indirectly arising from purchaser’s use or inability to
use the merchandise, or for loss or destruction of other property or from any other
cause, even if Dekolink has been advised of the possibility of such damage. Some
states do not allow the exclusion or limitation of incidental or consequential damages
so these limitations may not apply under certain circumstances.
The liability of Dekolink shall in no event exceed an amount equivalent to the
purchase price paid by the purchaser for the defective product.
This warranty shall not be extended, altered or varied except by a written instrument
duly signed by Dekolink.
