2. Why repeater

2.1. Reason 1

1) Blind or weak signal areas are formed if the buildings are too far away from BTS, or the buildings

themselves shield or absorb the signals.

2) There are too many complicated signals in the higher part of the buildings, therefore ping-pong switching

effect has been formed and the signals fluctuate a lot, there are annoying noises during phone calls and

there are dropped phone calls accordingly.

3) Elevators and basements are well-known blind areas.

4) Downtown areas of the cities, congested with many high-rise buildings are usually the weak or blind

areas.

2.2. Reason 2

The remote villages, mountains, hills, valleys, etc. are mostly scarcely populated areas with quite few mobile

users, so the main target is to send coverage to these areas, and it will not be cost effect to install a BTS tower,

therefore a repeater is a quite good option.

Can we not use mobile phones? The answer is definitely NO. But it might be much more miserable that the

communication can’t be achieved due to no or weak signals though there is a mobile phone.

Will your customers stay comfortable when there is no smooth communication in your shops or restaurants?

Will your business be influenced if your clients couldn’t call you through due to weak signals in offices?

Will your life be influenced if your mobile is always “out of service” at home when your friends call you?

How to solve the problems?

Best Solution:

Plug & play: Purchase a set of repeater solution and install it at your home, offices, and plug on the

power and immediately you would be able to enjoy the full bar and high quality signals!

Question: Will repeater increase the RF radiation?

A: No, it will decrease instead.

As it can be searched easily through internet, the tower would “order” the mobile phone to increase its output

power, in order to ensure successful connection when the mobile signal bar is few, there will be stronger mobile

output power level when the mobile signal bar is less and the strongest one can reach 2W (GSM); moreover,

the mobile phone is usually as near as less than 5cm to human body when people are in phone calls. Not only

it influences badly the human bodies, but also run out of the battery power much more quickly; usually the

mobile phone gets hot in such status.

The maximum power level of JD60-7-TB-US is 0.01~0.1W, and it decreases to be maximum 0.003W when

reaching server antenna. And since the server antenna is installed over the ceiling or onto the wall, there are

usually more than 3 meter away from the human body, 3meter away means at least 40dB propagation loss, or

10000 times less, 0.0000003W, therefore it is too weak to influence human bodies though it is still a very good

signal for mobile phones.

And when a repeater is installed, it improves the mobile signals in the coverage, and the successful phone call

can be connected easily with a much less power level of the mobile phone, thus it will reduce tremendously the

RF radiation.

3. Introduction

This JD60-7-TB-US full duplex mobile communications repeater from JDTECK INC is the perfect solution for

providing a wireless improvement in the cellular reception of a home, office, restaurant, VIP Room, apartment,

building or shopping mall, in the quickest time possible. One repeater covers 300 to 600 square meters.

It is designed to improve the call quality of an area by receiving, amplifying and re-transmitting signals of the

base station into a specified area via the server antenna of the repeater.

This repeater has Manual Gain Control (MGC) feature that enables engineers to reduce the gain of the repeater

manually if oscillation is detected or too strong input power level during installation, this will help to get the best

coverage effect without any interference back to mobile network.

And to maintain safe and specific output signal levels during the repeater’s operation, this repeater has a built-in

signal oscillation detection circuit to adjust the gain automatically so as to avoid interference to the cellular

network, also it gets color changing LED’s indicate its environmental status: the Alarm LED’s located on the front

of the unit (Alarm Low & Alarm High) will change color from green to orange or red, (depending on the input

power level) if the system detects signal oscillation in either band or, if the input signal is beyond a safe limit.

Below diagram shows how simple and fast repeater system is installed and works effectively: one wide band

directional antenna, as a donor antenna, has been installed at the top of the roof to pick up good mobile signals

from outside, and send through a 5D-FB cable to a JD60-7-TB-US repeater to be amplified significantly, then the

output signals are divided into three signals by a 8dB coupler and a 2way splitter, sent to three indoor omni

antennas and finally transmitted into the coverage area. Very clear phone call or high speed mobile data services

are immediately effected within the area.

5. Block diagram and work principle

The triple band repeater is a bi-directional repeater that consists of three mobile systems, the three systems

are combined together by a combiner, and each system gets their independent uplink and downlink power

amplifying system, and each link consists of duplexer, LNA, Filter and PA. The triple band repeater downlink

receives, amplifiers and retransmits the signals over the air from BTS to the coverage area; at the same time,

the uplink receives, amplifies and retransmits the signals of MS back to BRS, therefore a successful

communication is accomplished.

Modules in the system diagram:

zCombiner: a combiner helps to combine signals of three mobile systems together, and at the same

time to keep independence of each system and avoid their interference of each other.

zDuplexer: The main purpose of duplexer is to combine downlink and uplink to share the same

antennas, the duplexer is composted of one pair of band pass filter that can not only reject the

spurious interference, but also increase the isolation of Uplink and Downlink

zLNA: LNA is the first active sub system of the repeater, of which low noise and high linearity is

requested under strong input signals. LNA is the major sub system that determines the noise figure

of the repeater system.

zPA: The power amplifier sub system helps the repeater to reach its targeted output power, linearity

of which decides the linearity of the repeater

zPower supply is to supply power electricity to all repeater’s modules

6. The repeater system

zDonor Antenna：

¾5~7dbi outdoor panel or 7~9dBi wide band Yagi are recommended as donor antenna.

¾Function: Pick up donor signals from the BTS and send to the repeater by cable; the received

signals’ power level and quality influence a lot on the coverage effect. Donor antenna also

transmit the uplink signals from the repeater to BTS.

zServer Antenna:

¾2~3dBi indoor omni ceiling or 5~7dBi indoor panel are recommended.

¾Omni antenna (Indoor ceiling omni antenna or whip antenna), suitable to installed in the center

and radiate all direction; It is better to use a directional panel antenna or Yagi when the coverage

shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural

open space)

zCables: LMR 300 or 400, 5D or 8D –FB coax cables are recommended.

zSplitters or couplers: when the building structure is too complicated or there is big loss due to thick

walls, etc., splitters or couplers shall be used so that more antennas can be installed in more areas

to distribute the signals to each corner of the coverage area.

zPower Box including electricity meter, air switch and groundings, some sites might need surge

arrestors.

zNote: because this triple band repeater is a broadband repeater, so band in requirements contain

antenna, splitter and coupler in this system is 880-960MHz and 1710-2170MHz.

zThis device complies with part 15 of the FCC Rules. Operation is subject to the following two

conditions: (1) This device may not cause harmful interference, and (2) this device must accept any

interference received, including interference that may cause undesired operation.
