1. Preface

Personal mobile communication is now part of daily life and persons have

come to expect a robust network that meets their increased demand for an

always-on network that provides seamless coverage and unlimited bandwidth

at high speeds. Cellular repeaters are an integral part of achieving this goal.

A cellular tower in a non-metro environment typically supports a large number

of users but is affected by a relatively small coverage footprint. Therefore, the

average number of users who can access it is limited and a large amount of

channel resources go unused. The best way of solving this problem is to use

repeaters to extend the BTS coverage to fully utilize the telecommunication

resources. Hence cellular repeaters are no longer considered as peripheral

devices to cover blind areas in the network but as part of the core network

itself. Extending coverage and maximizing the available network resources

and revenue growth for the operator.

The complete coverage approach is not only a prerequisite for a high quality

mobile cellular network, but also a factor that attracts users. From this point

of view, a network operator should first consider providing a radio network

architecture with complete coverage in mind. This includes seamless

coverage in urban areas, heavy traffic areas, office buildings, supermarkets,

and hotels as the first step. Cellular repeaters successfully aid in

accomplishing this.

With this in mind, JDTECK has focused on successfully developing advanced

repeaters that are applicable to any mobile network and indoor distributed

antenna system (DAS). Repeaters are available to support any technology or

frequency in use today.

Because a large amount of BTS or Node B devices are deployed in densely

populated urban areas, there is usually no large blind area, therefore

repeaters are predominantly used to provide coverage inside buildings, sub-

ground locations or rural outdoor areas. Typically, radio frequency (RF)

repeaters are used when optical fibers are not available in buildings or when

using a fiber solution is not cost effective.

Since the number of repeaters on a cellular network usually increases with

the number of buildings to be covered in a specific sector, multiple repeaters

may end up feeding from one BTS or Node B. In view of this, the design of

the DAS is extremely important to maintain an acceptable noise floor and

thus achieve seamless integration to the macro network especially in densely

populated areas.

2. Introduction

JDTECK has engineered an advanced industrial grade digital repeater for

Distributed Antenna Systems with the ability to function in either a wideband

or narrow band mode. This core component helps create the perfect solution

for providing a wireless improvement in the cellular reception of a large office

or apartment building, hotel, underground parking garage or remote outdoor

location.

It is designed to improve the call quality of an area by receiving, amplifying,

filtering and re-transmitting the signals from the macro base station into a

specified area via a distributed antenna system (DAS.

This highly advanced digital unit uses a Graphic User Interface (GUI) to

access and select the desired active bands or channels, set any alarm trigger

points as well as configure and control the parameters of the repeater which

by extension controls the entire DAS it’s mated to either locally via USB or

remotely via Ethernet.

To maintain safe and specific output power levels, the GUI of this industrial

grade digital repeater has a wide range of configurable settings which allows

the repeater to function strictly within the parameters set by the end user.

These features include built-in Signal Oscillation Detection circuits with

color changing indicators for the respective bands (Green, Orange or Red

depending on the intensity), Automatic Gain Control (AGC) which will

dynamically reduce the gain of the repeater up to 10dB if oscillation or a high

input signal is detected. Manual Gain Control (MGC) to bring the repeater

into a set safe operating limit as well as a Network Safe / Auto MUTE

feature that immediately shuts-down the RF transmission circuit of any

frequency band that exceeds its set output power limits. There is also an

Uplink Sleep mode which shuts down the UL band of the repeater if no

activity is detected on the DAS after a set period of time. All features that

rigorously protect the macro cellular network from harmful interference.

There is master alarm indicator on the header of the GUI as well as an

external LED on the enclosure of the repeater which changes color from

green to red to alert the user if any alarm is detected. The user also has the

option to have the repeater send automatic email or SMS notifications to

specific addresses or numbers alerting the recipients to access the repeater

to make any needed adjustments.

This multiband industrial grade digital repeater from JDTECK is truly a very

user friendly, flexible and highly intuitive device that customers and system

integrators alike will enjoy using for many years to come.

3. DAS Installation

1. The repeater’s main function is to improve weak RF signals to an area.

2. Selecting the appropriate accessories that are compatible with this digital

frequency repeater is very important for optimal system performance. Since

this is a multiband repeater, it’s important that all the peripheral components

used in the DAS supports all the frequencies that are going to be needed

and that all the components are Low PIM rated.

3. The signal strength and quality at the donor antenna directly affects the

efficiency of the indoor coverage. Therefore, it is very important to choose

the location of the outdoor antenna carefully. With this in mind, it is

recommended that the donor antenna be installed in clear line of sight

(LOS) to the serving sector/s.

4. The repeater is a two-way (full duplex) digital signal amplifier so, there needs

to be proper isolation between the outdoor antenna and indoor antennas in

order to avoid signal oscillation of the repeater. (Feedback) There needs to

be more than 15dB of isolation above the repeaters gain. For example, if

the repeater gain is 80dB, then you need 95dB of isolation between outdoor

antenna and indoor antenna.

5. The repeater gain is adjustable for both the uplink / downlink individually.

Depending on the environment, the end-user may need to adjust the

repeater gain to achieve optimum performance and desired coverage.

6. The repeater is designed to amplify the input signal, filter it and retransmit it

to the desired area via service antennas. In order to reach the best

performance, the outdoor signal should be better than -80dBm with an Ec/Io

<6 and an RSRQ of <12dB. If the outdoor signal is very weak, then a pre-

amplifier may be used.

7. Calculating the Link budget before setting the repeater gain.

Link budget calculation:

Outdoor signal strength – Loss of accessories (cable, connectors, splitters,

Directional Couplers, Path Loss) + Antenna gain (outdoor antenna, indoor

antenna) + Repeater gain = Indoor signal strength.

8. For all cellular applications, you should only use 50 Ohm rated coax.

Besides affecting voice quality, using any other impedance of coax will

affect the throughput performance of services over LTE as well as shorten

the life of the repeater.

System Optimization

3.1 Installation Procedure – Cont.

 Check the contents supplied against your packing list & DAS design.

 Identify a suitable location where the donor antenna will be installed on

the roof or at an elevated location free of any other antennas or

immediate obstructions. Confirm this location has the best input signal

for the carriers you would like to support using test equipment. Ensure

the location is properly isolated from any of the indoor service antennas

so as to avoid signal oscillation.

 Identify the location for the head-end equipment and that suitable AC

power and a lightning ground is available. Using the DAS design

provided, walk the entire space to confirm all the components and cable

access paths of the DAS can be installed without any omissions.

 Install the donor antennas at the suitable location identified and start the

cabling process. DO NOT COIL UP any excess coax or create any

service loops in your system. These are detrimental to cellular

performance. Be sure to weather proof all your external connections and

fire stop all ports of entry.

 Carefully follow your DAS diagram to ensure all the components are

installed according to the design. Any alterations made to the system

layout without informing the DAS design engineer could result in poor

system performance or interference to the macro.

 It’s EXTREMELY IMPORTANT that all your cable terminations be done

properly and line sweeps completed using the appropriate test

equipment. (Frequency Return Loss) Directional couplers MUST be

installed in the right direction and with the correct values as outlined in

the DAS design. DOUBLE-CHECK ALL YOUR WORK! The extra time

you invest to do so will pay-off with a smooth and successful

commissioning process.

 If multiple repeaters are deployed, start by commissioning one repeater

at a time. It’s best to start with the frequencies that support voice

communication, then move on to data (4G, 5G, LTE). Upon

commissioning, quickly work towards getting the LEDs on the repeater to

a green status by adding attenuation as needed. First on the DL, then

on the UL.

 If signal oscillation or a strong input signal is between 1~4dB over the

acceptable range then the field alarm for the respective band will turn

orange (See manual gain adjustment). If the signal oscillation is between

10-15dB then the field alarm for the respective band will turn red and the

circuit will then go into MUTE / Shutdown (Grey). This is as a result of

not having enough isolation between the donor and service antennas or

the input signal at the donor antenna is too strong.

3.2 Installation Procedure – Antenna Mounting.

 In this case, attenuate the DL gain on the repeater and then match the UL

gain to the same gain value. After each gain adjustment is made, click the

power cycle tab on the GUI. This will take the repeater out the MUTE /

Shutdown state. (See attenuation settings for adjustments)

"The installation height of the antenna for AWS band (1700/2100 MHz)

operations is limited to 10 meters above ground for compliance with 47

CFR 27.50

 Do not install the donor antenna near high voltage power lines.

 Please take the necessary safety measures when working on heights.

 Do not mount near or in the path of other antennas or satellite dishes.

It is recommended that you mount your donor antenna in a spot that is

free of any immediate obstructions. Making use of a dedicated mast or

mounting bracket is recommended for optimum antenna performance.

3.3 Installation Procedure – Repeater Mounting.

The JDTECK industrial digital repeater is designed to be mounted on a wall.

Carefully remove the repeater from the box and place it upright on a

protected surface like cardboard or carpet. Then remove the mounting

bracket from repeater and securely bolt bracket to the wall. Be sure to use a

plumb level so the bracket is perfectly straight when completed.

Install conduit from above ceiling to communications board, route coax

through conduit, then slide repeater onto bracket.

3.3 Installation Procedure – Repeater Mounting Cont.

4. Installing the Graphic User Interface. (GUI)

A USB thumb drive is shipped with each repeater which has the GUI program

stored on it. Install the GUI program onto a Laptop PC that will be used to

initially access and configure the repeater. Please note that the GUI can only

be initially accessed via a USB cable connection. You will also need to have

an internet connection to download Java.

Click on file name JDTECK_GUI.exe to install program. Please allow a few

seconds for process to start.

The following error will most likely pop up. Go ahead and click yes.

You will then be prompted to start the install sequence. Click next. Be sure to

leave the check box selected to create a desktop shortcut.

4.4 Accessing the GUI. (Con’t)

If the GUI screen comes up blank, it’s because Java did not install

correctly. It would be easiest to just reinstall the program again

from the thumb drive where you would again be prompted to

download the correct Java Kit and restart the install sequence.

Upon a successful installation, the following screen will appear. Here you will

select the connection type (USB), the device type (DR-27) and the COM

Port. This is typically COM Port 4, however you can double check by going

to Device Manager on your PC to see which port is active.

4.5 Accessing the GUI. (Con’t)

When the correct COM Port has been selected, the following screen will

appear. Click OK to proceed.

The first screen to appear is the Band Select Page. On this page, the user

will select which bands they want to support. You also have the option to

assign the repeater a name or ID on this page at the header.

16

17

5. Using the GUI. (BAND SELECT)

The GUI is inherently intuitive and very user friendly. The user simply selects

the bands they would like to support and click confirm. They can choose from

either the preset band selections or customize a selection as needed. In the

custom selection mode, the user can select all the bands at the very top

which will activate all the blocks within the bands. This will allow the repeater

to run in wideband mode. (All Channels in All Bands). Ideal for enterprise

deployments where the user would like to support all carriers.

The user also has the option to select multiple non-contagious blocks or

channels they would like to support. (2) for 700 MHz, (2) for 800 MHz,

(4) for 1900 MHz and (4) for AWS. These are typically used in carrier

applications. No matter which options are selected, the user must remember

to click CONFIRM for the GUI to register the selection. Please note that

clicking CONFIRM will NOT send the repeater into transmission mode, it will

only log the data inputted or selected. This allows the user to continue with

setting up the parameters and alarms for the repeater even before going live

with transmission.

There are several other neat features you will notice on the header as well as

internal of each page. These include:

 A MASTER ALARM on the top left which is synced with the alarm LED on

the outside / bottom of the repeater enclosure so even if the user is not

logged into the GUI, they can observe if an alarm is present or not.

 A dynamic ICON on the top right of the GUI that indicates how the user is

interfaced with the GUI. Either via USB or Ethernet.

 A CONFIRM button that registers the selections on each page.

 A RESET button which resets all the settings on that page to factory default.

 A RECALL button which will repopulate the fields with the last saved

selection.

 Bold, easy to view, color changing navigation tabs on the left so at any time

the user knows which page they are on or where to navigate to next.

 A dynamic TX & RX status indicator to show communication activity between

the GUI and the repeater.

5.1 Using the GUI. (SET PARAMETERS)

The SET PARAMATERS page allows the user to set the high-limit (not to

exceed) points of the repeater on the bands that were activated on the

BAND SELECT page. Only the active band fields are editable. The user

can individually adjust the UL and DL attenuation values which directly

influences the Output Power for each respective band. This page also

displays the status color of the respective band so the user knows which

band to adjust. Once on this page, the response to the adjustment is not

dynamic, so the user will need to click on the dashboard to see the effect.

Also working fixed within the program is an Automatic Gain Control

feature (AGC) which dynamically adds attenuation to the respective band to

maintain the output power limit set by the user for UL and DL.

Because the repeater has dynamic AGC, the status fields will only change

color from Green to Orange or Red when the AGC threshold has been

exceeded. An infringement that is between 1-5dB over the AGC range will

change color from Green to Orange. If between 6dB and 10dB, it will

change to Red. If above 10dB, the respective circuit will go into active

MUTE / Shutdown. To get the unit out of MUTE, first add more DL

attenuation to the respective circuit, power cycle the repeater’s transmit

circuit and then click on the DASHBOARD to see the change. The fields on

this page come preset from the factory with the following values:

 20dB of attenuation on the UL and DL.

 17-20dBm Output Power Limit for the UL.

 21dBm Output Power Limit for the DL.

18

19

5.2 Using the GUI. (SET PARAMETERS)

On this page, the user also has the option to select up to any 5 bands they

would like the QUICK VIEW DIALS to monitor which dynamically display the

DL output power over on the DASHBOARD page.

4. Using the GUI. (SET ALARMS)

On the SET ALARMS page the user can set the trigger points for when an

alarm will activate and display RED or optionally send an automated

notification out to as many as 4 users simultaneously. The parameters

monitored on this page include Low RSSI, Low Output Power, MUTE

activation and Signal Oscillation. The user can define what they consider to

be a low threshold point when an alarm should be triggered and a notification

sent for the RSSI and Output Power limit. They also have the option to select

if they want a MUTE or Oscillation notification sent out as well. If the email

and SMS fields are not populated, alarms will just be displayed and logged.

5.3 Using the GUI. (DASHBOARD)

The DASHBOARD page provides an overview of how the repeater is

functioning. The view of this page dynamically changes depending on if the

repeater is operating in preset or custom mode.

The RSSI, AGC, MGC, Output Power, UL Overdrive, UL Sleep, MUTE,

Alarms, Operating Temps and Quick View Dials are all dynamically

displayed in real time on this page. The user gets to see when the output

power exceeds the set limits and exactly how much AGC is being added to

keep the repeater within the set output power limit range, as well as when

any threshold limit is exceed which will then send the respective circuit into

active MUTE / Shutdown.

Because of this, it allows the user to easily determine exactly how much

additional MGC is needed to prevent the repeater from going into active

AGC mode and maintain a stable output.

This page also has a unique feature called an UL Overdrive Alarm. This

alarm was designed for scenarios where the DAS is also providing coverage

to an underground parking garage and someone enters the garage with an

in-car signal booster which inadvertently sends the respective UL circuit

beyond its set UL limit. The repeater detects this and immediately adds AGC

to the respective circuit in order to protect the macro from severe

interference. If the AGC range is exceeded (10dB) the respective circuit

then goes into MUTE and then attempts the auto restart sequence.

20

21

5.4 Using the GUI. (REGISTER)

The REGISTER page allows the user to document the contact details of who

owns the repeater as well as who installed it.

A warning label is also displayed on this page.

5.5 Using the GUI. (VIEW LOGS)

The VIEW LOGS page allows the user back and review the type, value,

band, date and time an alarm occurred. They also have the option to

download the logs to excel.

6. Testing. (Flow Chart)

IMPORATNT SAFETY INFORMATION

The outdoor antenna used for the purpose of communicating to the wireless

infrastructure is limited to 23 dBi, or any combination of gain and loss that equates

to 23 dBi at output. Each antenna must be positioned to observe minimum

separation requirements from all users and bystanders.

The following guidelines should be used when considering separation distances.

INDOOR antennas must be placed such that, under normal conditions, personnel

cannot come within 20 cm from any inside antenna.

OUTDOOR antenna must be positioned such that, under normal conditions,

personnel cannot approach closer than 103 cm. A directional antenna having a

maximum gain of 23 dBi is used, precautions should be taken to prevent personnel

from routinely passing closer than specified.

7. Troubleshooting

Q1. Why is there still no signal after installing the equipment?

Answer:

1. Check the power on repeater and power supply.

2. Check the connector of outdoor antenna is tight or not.

3. Check the connectors of RF cable are tight or not.

4. Check the outdoor signal is strong enough or not.

5. Check to make sure the antenna is installed correctly.

6. Check the connector of indoor antenna is tight or not.

7. Check the cable type is suitable or not.

Q2. Why the signal strength is too weak on the edge of area?
