We strongly recommend you to read the user guide completely before beginning
the installation.
HiBoost SmartLink booster provide 2 options of booster installation,
APP and LCD installation ways are unique methods provided by HiBoost.
This installation guide will take the HiBoost 4K SmartLink as an example.
1. App assisted installation,
FIRST CHOICE From Page 09~22.
It’s more convenient and many work could be done by ONE
person, and the most important is that the obtained signal
can be very precise.
2. LCD assisted installation,
SECOND CHOICE From Page 23~35.
It can achieve the same precise effect as App guidance.
But it may need two people and the installation process is a
little cumbersome.
LCD signal meter tells how
strong the signal is

The App helps you find the
best signal outside

Then why has HiBoost spent extra big efforts and costs to design APP and
LCD signal meters to help you install?
Out of the various reasons, the most important reason is that we would like you, our
valuable client, to get the maximum output power from the booster system in order to get
optimal signal reception for all your mobile devices.
As it is known and a big thanks, FCC makes signal boosters legal in 2014 so that every
body can install and benefit from the signals;
But FCC regulations do limit the gain and output power of all consumer boosters to low
values in order to avoid any interference to the cell towers;
Furthermore FCC stipulates that any improper install should trigger immediately further
reduction of the booster’s already-limited gain and power to protect the towers.
Therefore, you can understand how important you need to find the perfect outside
signal from the tower and how important to squeeze every last gain and power from
the booster, even 1dB more power is so precious when you suffer from no signals.
HiBoost App & LCD signal meters will help you to fine tune the best power and get
as much cover of your spaces.

General Working Principle:
※Please do spend sometime to read it fully, as it is crucial to get full bars for your rooms.
Before we start any of the two ways, please allow us to spend 3 pages to make you
understand how the booster system works for you.
How HiBoost booster works
1. Outdoor antenna receives outside
signal from the nearby cell tower and
sends it to HiBoost Booster
2. The booster amplifies the signal
and sends to indoor antenna
3. Indoor antenna receives amplified
signal and send it throughout your
rooms
Vice versa, indoor antenna receives cellphone signal and sends to the booster
The booster then amplifies the signal and sends it to outdoor antenna
Outdoor antenna sends signal to the cell tower
Then you can make phone calls and internet streaming.

Out of the Formula:
Outside Signal: To be received by outdoor antenna from cell tower
Outdoor Antenna Gain: The gain of outdoor antenna
Outdoor Cable Loss: The loss of the outdoor cable
Booster Gain: The actual working gain of the booster
Indoor Cable Loss: The loss of the indoor cable
Indoor Antenna Gain: The gain of indoor antenna
For example:
-65dBm + 11dBi - 4.5dB + 60dB - 2dB + 7dBi = 6.5dBm (System Output Power)
Since the figures in Black color are fixed when you finish the purchase, thus the RED
figures of
1. Outside Signal
2. Booster Gain will play a vital role in reaching the best output power during the
install, especially when we know the FCC limits the booster system values.
So the user guide is focused on:
1. Getting the best outside signal.
2. Keeping the maximum booster gain.

More notes on how to keep the maximum booster gain
※Please note: This separation is not an absolute mandate. The idea is to isolate
the outdoor antenna from the indoor antenna.
1) Increase the distance between the outdoor and indoor antenna, generally the same
vertical distance generates more loss than horizontal, and to follow easily, a Typical
Required Distance Between Outdoor and Indoor Antenna Over 30 feet (10 meters)
horizontal distance or 13 feet (4 meters) vertical distance.
2) The outdoor and indoor antennas shall be back to back.
3) Use barriers between the indoor and outdoor antenna.
The loop back from the outdoor antenna to the indoor antenna will reduce the gain, so
the principle to keep the maximum booster gain is to avoid the loop back from the
outdoor antenna to the indoor antenna.

APP Assisted Installation
We are going to use 3rd party apps:
To find the cell tower location
To test the signal strength and quality
There are a variety of resources available online: Opensignal,Cell mapper,
Network cell info lite, etc.
Please download them beforehand over Android and / or iOS:
※You can use either of them to your favor. Here we are using
Opensignal and Network Cell Info Lite as first two choices.
Step 1: Download the 3rd Party Mobile apps

11
Step 2: Download Signal Supervisor app and connect the booster
1) Search “Signal Supervisor” on Google Play/ App Store, or scan the above QR Code
to download.
2) Register on the Signal Supervisor app.
3) Switch on the booster.
* Connect the Bluetooth/WiFi antenna with booster, and there is no need to connect
outdoor or indoor antenna at this moment.
4) Click “Add Device” to register the booster into the APP. And we recommend WiFi
connection because the Bluetooth connection can’t go beyond 30ft.Check more steps
about the app uses as below.
Download the Signal Supervisor app,
register ID and booster.

Remark: Due to the phone types and the WiFi router types, there are few cases though
rare that the booster won’t be linked successfully to the signal supervisor app, even after
our technical support. In such case:
* Please kindly switch to use LCD signal meter to assist your install and will have the
same result. And Bluetooth/WiFi disconnection won’t influence the booster working status
at all.
* Or please use different phone or change your WiFi router if you really want remote
monitor.
Please contact our tech support and we will see what the best arrangements can be for
you.
Step 3: Look for best outside signal and install outdoor antenna
The performance of the booster system is heavily dependent on the successful installation of
the outdoor antenna
3.1 Connect the booster with outdoor antenna
(1) Put the booster near to the location you would like to install in the future, or a place with
power outlet temporarily.
(2) Keep the booster connected with Bluetooth/WiFi antenna.
(3)Switch on the booster and make sure the signal supervisor app links with it smoothly.
(4)Connect the 16.4ft cable with the booster’s outdoor port. The booster supports hot plug.
(5) Then connect the window cable with 16.4ft cable and pull the window cable outside and
connect it with 32.8ft cable. In case window cable is not needed, connect the 16.4ft cable with
32.8ft cable directly.
(6) Connect the other side of 32.8ft cable with the outdoor antenna.
32.8
*HiBoost 15K SmartLink can be directly connected to the outdoor antenna with the 50ft
NM-NM cable.

14
Notes:
* It is a must NOT to connect indoor antenna at this moment as it will influence the outside
signal finding.
* Please place the booster outdoor within 30ft to the possible location of outdoor antenna if
there is only Bluetooth connection. This is to ensure the App links to the booster.
Bring your mobile phone with the APPs and the outdoor antenna to the location where the
best outside signal can be found. The outdoor antenna is recommended to be at the four
corners or high end of the roof, or attic.

3.2 Select the possible location for best outside signal.
The outdoor antenna needs to maintain a clear line of sight with the cell tower. And it is
necessary to avoid the roof or other stuffs from blocking the outdoor antenna.

3.3 Use 3rd party APP to locate the tower(s)
(1)Insert your detail address in “Search city” box. (following figure 1)
(2)Enter signal dashboard, and click “CELL TOWERS”. Then zoom in map to find best
one, it will show a blue line with your place which means your cellphone connected
one. (following figure 2&3)
(3)When you find such location, check the strength, test voice and data speed. A good
signal shall not only be strong, but also be clear in voice and fast in data speed.
(following figure 4-6)
Figure 1 Figure 2 Figure 3
Figure 4 Figure 5 Figure 6
Now open “Opensignal”, use it to detect the approximate position of the nearby cell
tower.

16
You can also use the “Network Cell Info Lite” to locate the tower and measure the signal
strength before & after install.
The good point of Network Cell Info Lite is that you can see the signal levels.
But it seems to be only available for Android.
Network Cell Info Lite
The signal strength requested by the booster system is as below.
SIGNAL
STRENGTH
3G/1X
4G/LTE
EXCELLENT GOOD FAIR POOR DEAD ZONE
Your signal strength is going to be a
good indicator of how fast you can
download and stream, but for voice,
it’s more like “Can I make a call, or
not?” If you can make a call you
should not care how many bars you
have, as long as the call goes
through and everyone can hear
everyone. Looking at bars is just
going to make you cranky.
The reason to test your internet speed
is to make sure you'll be able to stream
high-bandwidth movies, like those
from Netflix, Hulu, Amazon, and other
providers. If your internet speed is too
slow, you'll get choppy video or
regular buffering.

3.4 Look for the best location and direction of outdoor antenna
After the tower is located, please pick up outdoor antenna and point to the tower and adjust
its direction precisely.
Watch the signal gauge of Signal Supervisor App as it will show the booster’s best output
power when you get the strongest outside signal.
Target: Try to get the highest possible output power for each band and try to make 2-3 gauges
turn green.
1) You can either look at the signal meter value, 10dBm is the best
2) Or you can look at the signal description, Super is the best
Notes: The output power level in the signal meter is the level for the indoor antenna.
• Keep in mind that it is normal for the output values may vary dynamically between 1-3 dB
• To optimize the signal for one carrier, point the outdoor antenna towards the closest cell phone
tower designated to that carrier
• To optimize the signal for more than one carrier, point the outdoor antenna between multiple
towers
• Make sure to slowly turn the antenna while taking the readings so the booster has time to
adjust the reading
• Test and install the antenna at the same height where power outputs and gain values reach
the booster’s maximum capacity
• If you can’t get a good output power, which is even below poor, most probably the install
will fail. Either please find a new place to find good signal again, or drop the install.
Professional Tips
Fix the outdoor antenna direction when you get the best output power.

3.5 Fix outdoor antenna
Now install the outdoor antenna firmly
The connector of the cable connection part must be glued with black waterproof tape to
prevent long-term signal drop and reduce signal loss!
Please do take following screen shot for future comparison
during indoor antenna install.
What you are going to be paying attention to here, is the gain
values. If you have interference between your indoor and
outdoor antennas, then the booster will lower the gain and
these values will decrease.
3.6 Reconfirm that the signal on signal gauge is the best!
