Cel-Fi Setup

Follow

Last updated by Allan B

Overview

The Cel-Fi is an easy-to-use system that boosts signal from the GSM network in your home or office without Internet or GPS connectivity.  

The system consists of two units

  • window (or network) unit
  • coverage unit

The window unit is placed at the point where the 3G signal is strongest and the coverage unit is placed in the center of your home or office. The coverage unit then transmits signal from the window unit significantly improving signal in the area for both voice and data.

 

Requirements

Using the Cel-Fi Signal Booster requires:

  1. A 3G-compatible GSM device
    • If you have a 4G or LTE device, make sure your device is set to use 3G data as well (see image below)
  2. An area inside the home that receives at least one bar of 3G signal  or better (4G or LTE)
  3. Easily accessible power outlets

 A device connected to the Cel-Fi will place calls even if both data and Wi-Fi are disabled and Wi-Fi calling works while device is connected to Cel-Fi.

Requirements

 

 

Setup

A. Find the spot with the best 3G coverage.

  1. Use your GSM device to find the area in your home or office with the most bars of 3G signal. This will usually be near a window and on the highest floor.
  2. You must see the 3G signal (or 4G or LTE) signal icon on your device.

B. Plug in the window unit and check the signal strength.

  1. Attach one of the provided power supplies to the window unit. It doesn't matter which one you use because they're both the same.
  2. Plug the window unit into an easily accessible outlet near the area with the strongest 3G signal (or better).
  3. There should be at least one bar of signal showing up on the unit. If there isn't, you'll need to move it to another spot.

C. Plug in the coverage unit and find the best spot for it

  1. Find the spot in your home that is in most need of improved coverage (or where you'll use your device the most). The coverage unit should be placed as far away form the window unit as possible.
  2. Plug in the coverage unit and wait for the LEDs on the display to stop cycling; this might take several minutes.
  3. Once it stops, check the display. If the device is set up properly, the green icon will appear on the display to the left of the number.
  4. For the best signal, move the coverage unit around until it displays an 8 or 9 for coverage quality.
  5. If the coverage unit is too far away from the window unit, a red icon will show up on the display and you'll need to change its location.
C. Plug in the coverage unit and find the best spot for it

 

 

Troubleshooting

Window Unit  

POWER/STATUS INDICATOR

SOLUTION

NOT LIT

Check if the unit is plugged in and that there is power coming from the outlet. Try using the power supply from the coverage unit to rule out a problem with the supply itself.

SOLID RED

Unplug the unit, wait a few minutes and plug it back in.

FLASHING RED

Make sure all the vents are unblocked and/or try moving the unit to a cooler location; then wait for it to cool. It will start working normally again when it cools down.

FLASHING GREEN
Longer than one minute

Make sure neither of the units is close to a Wi-Fi router and then wait at least 30 minutes. It can take that long for unit to go through the verification process.

SIGNAL INDICATOR

SOLUTION

NOT LIT
But Power/Status is lit

Move the window unit to a spot with better coverage.

CYCLING

There is a software update in progress; wait for it to complete. Do not unplug the unit.



 

Coverage Unit

HOUSE ICON

SOLUTION

RED LIGHT

Confirm that the coverage and window units have the same serial number (are a pair). If they are, move the coverage until closer to the window unit.

GREEN ZERO
Next to the icon

Move the coverage unit farther away from the window unit.

RED POWER/STATUS INDICATOR
In the house icon

Unplug the unit, wait a few minutes and plug it back in.

GREEN NUMBER LESS THAN 8
Next to the house icon

Move the coverage until farther away from the window unit until the number gets higher. Ideally it should be an 8 or 9.

NUMBER DISPLAY

SOLUTION

CYCLING
The separate LEDs that make up the number on the display are cycling

Make sure neither of the units is close to a Wi-Fi router and then wait at least 30 minutes. It can take that long for unit to go through the verification process.



 

Error Messages

ERROR

PROBLEM

SOLUTION

ERROR E1

The unit is not picking up a network signal.

Move the window unit to a spot with better coverage.

ERROR E3

The coverage unit is overheating.

Make sure all the vents are unblocked and/or try moving the unit to a cooler location; then wait for it to cool. It will start working normally again when it cools down.

ERROR E4

The window unit is overheating.

Make sure all the vents are unblocked and/or try moving the unit to a cooler location; then wait for it to cool. It will start working normally again when it cools down.

ERROR E8

A Wi-Fi network has too strong a signal for the booster to function.

Make sure neither of the units is close to a Wi-Fi router
