How it works
1. The outside antenna collects signal from the cell tower.
2. The outside antenna sends the signal to the booster through coax cable to the booster.
3. The booster amplifies the cell signal and rebroadcasts the signal indoors to all mobile devices within range.
4. The booster amplifies outgoing cell signal back to the tower.
How the SureCall Flare 3.0 Booster Works
OVERVIEW
Why indoor signal can be weak
There are several obstacles that can contribute to the poor reception you receive in your home:
• Distance to your carrier’s cell phone tower
• Obstructions caused by terrain and foliage
• Building materials like low-E glass, metal and concrete

BEFORE INSTALLATION
IMPORTANT. BEFORE YOU BEGIN.
IDENTIFY THE AREA OF STRONGEST OUTSIDE SIGNAL.
Since booster performance is largely determined by the signal strength received by your outside
antenna, it is important to identify the location of best signal for placement of your antenna.
The best location is generally found on the side of your home that faces your nearest cell tower and
as high as possible -- where the antenna can ‘see’ your cell tower. Better signal received by your
outside antenna means better booster performance inside. Conversely, the weaker your outside
signal, the more limited your coverage will be indoors.
If you’re unsure of the direction of your carrier’s closest cell tower, see page 9 for
suggestions.
DO NOT RELY ON CELL PHONE BARS AS AN ACCURATE MEASURING TOOL
Cell phone bars are an approximation of your signal that varies by phone and carrier. Placing
your phone in test mode or downloading an app that shows your signal in decibels (dB) is more
accurate. For help using this feature on your device, see “Taking signal measurements with your
phone” on page 7.
During planning, installation and testing, take multiple readings several minutes apart. Also, verify
that you can place and hold a call.
BETTER ANTENNA SEPARATION MEANS BETTER PERFORMANCE
Maintain a distance of at least 25 vertical feet or up to 50 feet of horizontal distance, especially if
sufficient vertical separation cannot be achieved. Also, make certain the antennas are aimed away
from one another.

Measuring signal will be helpful to (1) identify the location outside with the strongest signal for placement of your outside
antenna and (2) to measure indoor signal strength during installation and testing of your system.
During installation and testing, always take multiple readings several minutes apart. Also, take note of the band number
related to each reading for accurate comparisons.
NOTE, signal measurements are displayed alongside their measurement scale. RSRP is one scale commonly used, as is RSSI. For more
information, see “Signal measurement scales” on page 8.
FOR IPHONE dBm signal measurements, use the methods below.
1. First turn off your Wi-Fi
2. Dial *3001#12345#* then press the call button.
3. The field test screen will appear. Once open, the menu navigation varies depending on the iOS version.
4. Navigate to “Cell Info” in the menu
5. The measurement that reads “RSRP” is your cellular signal strength in decibel-milliwatts.
6. Note Band number
If you’re using an earlier version of iOS or looking for more detailed information, we have more instructions available
here: www.surecall.com/support
Taking signal measurements with your phone
Cell phone bars are an approximation of your signal that varies by phone and carrier. Viewing measurements in decibel[1]
milliwatts provides a more accurate reading. In most cases the units are reported in RSRP (LTE & 5G signals) and will
generally fall between -80 dBm (strong) and -130 dBm (very weak). If you are connected over 3G or HSPA the decibels
units are reported in RSSI and the units will generally fall between -50 dBm (strong) and -100 dBm (very weak).
PLEASE NOTE, To achieve optimal performance for your booster, it is vital to take care choosing antenna placement
and antenna alignment The coverage area that the booster provides is directly related to the strength of incoming signal
received by the outdoor antenna. Mounting the outside antenna where the signal is the strongest provides the best
results. If signal is extremely weak where the outside antenna is installed, indoor coverage will be limited.
See the instructions to measure decibels on your phone.

Signal measurement scales
The relationship between RSRP and RSSI is approximate and depends on the channel bandwidth, noise floor and
channel loading. The chart below displays the approximate equivalent of all four measurements:

Finding your closest cell tower
Since performance is largely determined by the signal received by the outdoor antenna, it is important to know the
direction in which you will aim your directional outside antenna before installation.
The best location for your outside antenna is generally found on the side facing your nearest cell tower and as high as
possible -- where the antenna can ‘see’ your cell tower.
Finding your strongest outside signal
If you’re not sure of the location of your nearest cell tower, there are resources available. You may utilize crowd-sourced
cell tower resources such as sites like www.cellmapper.net.
