This document provides information about a GSM signal booster from Dolphin Automation & Technology. It describes the product as a KW17A-GSM repeater that amplifies mobile signals in the 890-915MHz and 935-960MHz bands. It also explains how signal boosters work to receive a low signal from a base station, amplify it, and retransmit the signal to provide stronger coverage for mobile phones. Basic installation instructions are provided involving testing signal strength outside, installing antennas, running cable, and powering on the booster. Contact information is given for inquiries.

Why do you need to buy repeater/booster?

2. Cell phone becomes especially helpful when people get into critical situations. In cas
e of emergency a timely call can save somebody's life.
Unfortunately, there are still some places where they can find themselves "out of cov
erage" ,no signal at all... Usually those places are either too far from the cell phone ba
se station or located inside underground constructions, for example:
 Parking lots, tunnels
 Big stores, office buildings
 Cars, boats etc.
 House in remote areas
 How can repeater bring your mobile phone better signal?

3. •The outside antenna catches low signal from operator servicer's base station and deliver
s it to cell phone repeater through the connection cable (coax).
•After the signal is accepted by the mobile repeater, this device amplifies it.
•Then this amplified signal goes through the connection cable (coax) to the inside anten
na.
•And after that, the amplified signal transmits to your cell phone.
• Finally, your cell phone will get good signal, never on and off
A regular cell phone repeater consists of: (full kit)

How to install repeater (very easy and simple):
Step1: Use your mobile phone to test signal strength outside house or on roof, 70dbm is the basic requirement (full b
ar).
Step2: Install outdoor antenna in that location and keep adjusting, point it to signal tower station, try to get best signal
.
Step3: Run outdoor coaxial cable into building in a convenient location to connect with signal repeater
Step4: Mount your indoor antenna with signal repeater
Step5: Power up signal repeater device to check the signal inside, moving outdoor antenna until you get satisfied si
gnal.
Note: Connect outdoor ANT (BTS) port with outdoor antenna, connect indoor ANT(MS)
port with indoor antenna, outdoor antenna is mounted at a higher position. Both antenna
s should be 10 meters far away from each other at least.Indoor and outdoor antenna mu
st be separated by wall.
