No Signal Improvement on Phone

THE 3G & 4G MODE BUTTON

As GO will only boost one band at a time, you need to ensure that the mode selected on the GO button (either 3G or 4G) matches the signal you are testing on your phone. You could look like a silly sausage if testing the GO in 3G mode when your phone has a 4G signal.

Turning 4G on or off can be done in your phones setting. You may need to turn off your phone’s WiFi to see the 3G/4G indicator.

See the typical 3G indicators on my giant iPhone 12 Plus.

We have instructions on how to get exact signal measurements on your phone for iPhone or Android models, if you wish to be extra nerdy.

CHECK YOUR BOOST

Using the WAVE App you can check the level of ‘Boost’ being applied to the signal.

Ideally the Boost needs to be a number between 7 and 9 to see a noticable difference on your phone.

If you are not getting a number in this range see our section on maximising the GO setup

CHECK YOUR INPUT SIGNAL

Using the WAVE App you can check the input signal from the external antenna.

Ideally you need 3-5 bars, to help maximise this, see our section on maximising the GO setup.

MOBILE VERSION – SIGNAL TOO STRONG

If the signal at the outdoor antenna is strong, the GO Mobile version will not boost the signal.

3G: signal 4 bars or better (-80dBm) GO will not boost

4G: signal 4 bars or better (-95dBm) GO will not boost

This does not affect the GO Stationary version, which will boost all the time.

This feature is designed to protect the network, just in case a GO is at full boost and suddenly approaches a tower whilst moving.

To view your exact signal level use the WAVE App and check the Donor RSSI coming in from the antenna.

The ‘Boost’ indicator will be at 0 when not boosting and no alarms will be displayed.

Have Signal But Can’t Make Or Receive Calls

HAVE GO IN 3G MODE FOR VOICE

It is highly recommended that GO remains in 3G Mode so that voice calls are always supported.

Some phones and network towers do not support voice calls over 4G (VoLTE).

If you are only boosting 4G and attempt to make a VoLTE call in an area that does not support it, your call will fail if 3G fallback is not available.

The solution is to switch the GO to boost 3G so the phone call can go out over the 3G network.

Signal Only Short Distance From Indoor Antenna

CHECK YOUR BOOST

The output power on the GO is directly related to the ‘Boost’ figure in the WAVE App.

Open the WAVE App on your phone and check the ‘Boost’ number.

Make sure you have between 7 and 9 of boost on the indicator in a building, or 6 to 9 in a vehicle. The higher the better.

OPTIMISE BOOST

The system works at optimal boost, and has the largest coverage area, when the antennas are isolated from each other as much as possible.

The further you move them apart the larger the boost applied to the signal and the larger the coverage area and higher the bars on your phone will generally be. Also use solid objects such as a roof or walls to help with isolation.

The boost is represented by a 0-9 indicator in the WAVE App, with 9 being the highest.

VEHICLE SETUP

Position Indoor Antenna

As I mentioned 100 times before Isolating the antennas from each other is the key, this is more important in vehicles where antenna seperation is only a few metres.

The setup below in my virtual girlfriend’s car is with the external antenna in the centre of the roof and the indoor antenna is moved around in different positions so you can see the Boost figure in red.

The dB figure represents the boosted signal on the phone (-63dB was the best signal and -92 the worse). You will notice the higher the boost number, the better the signal level.

It also resulted in the signal spreading further..

For further information on setting GO up in a car visit our blog post Installing GO in a Car

No Connection to Mobile Network

CHECK FOR SIGNAL ON YOUR PHONE

GO will only boost a signal if there is some signal at the external antenna. Go to the external antenna with your phone and check for signal there.

If there is no signal then the antenna or your vehicle needs to be moved to a place with some signal.

If there is signal there then read on……

 

CHECK THE WAVE APP

Using the WAVE App you can check the input signal from the external antenna.

You will see signal bars and also the exact signal level for each band under ‘Donor RSSI’.

GO Stationary requires a minimum of -104dB of 3G signal or -120dB of 4G signal to connect to the network.

GO Mobile requires a minimum of -104dB of 3G signal or -120dB of 4G signal to connect to the network, but also will not boost the signal if already strong:

3G: signal 4 bars or better (-80dBm) GO will not boost

4G: signal 4 bars or better (-95dBm) GO will not boost

Error Messages on GO

Using the WAVE App you can check what the error light means.

BLINKING RED

NO SIGNAL MESSAGE

GO cannot receive a Signal from the network, or is unable to connect to a tower. Visit the Network Connection section on how to fix.

SOLID RED

TOO HOT….TOO HOT!

The unit is running too hot, this could be due to the weather, lack of ventilation or being in direct sunlight.

Try moving the GO to a cooler location. This feature helps protect the hardware from failure, once cooled down the system will start again automatically.

SOLID RED

HARDWARE ERROR OF DEATH

I have never seen this personally, but it is worth a mention.

It is a hardware error indicator, try repowering the unit and if the error persists then contact our technical department.

 

BLINKING RED

SIGNAL TOO STRONG MESSAGE

The input signal from the mobile network is too strong to use a repeater. Too strong…..are you kidding me? Yes the signal can be too strong.

Try moving your vehicle or external antenna on the building to an alternative location on the roof.

If the error persists then contact our technical department.

BLINKING RED

ANTENNAS ARE TOO CLOSE

The indoor and outdoor antennas are too close together, try moving further apart or help isolate them by having a roof or wall in between.

OTHER ERRORS

You may come across a few other errors, which are detailed in the GO Error Guide

Contact our technical department if you have any concerns.

MEASURE THE SIGNAL WHILE ON 3G & 4G

As your phone will only indicate a signal reading of either 3G or 4G, it is important to check both on your phone, Make sure your phone is connected on 3G (not 4G/LTE) before checking the signal indicator on your phone. Then turn back on 4G to test.

Turning off 4G can be done in your phones setting. You may need to turn off your phone’s WiFi to see the 3G indicator.

See the typical 3G indicators on my giant iPhone 12 Plus.

We have instructions on how to get exact signal measurements on your phone for iPhone or Android models, if you wish to be extra nerdy.

CHECK YOUR NETWORK UNIT

3G/4G Connectivity
The signal indicator on the PRO will advise if 3G, 4G or 3G/4G is being boosted by the icon above the signal bars. If you are in a 3G/4G area then make sure this is displayed on the screen.

Signal Strength
We need to ensure your Network Unit (large box) has a decent signal from the network of 4 to 5 bars of both 3G and 4G.

If there is a 3G/4G icon present, then the bars represent the 4G band. So if this is the case we need to check your 3G signal strength in the special ‘WAVE APP or nerd mode’ to see what is happening.

CHECK YOUR COVERAGE UNIT

Make sure your coverage unit (small box) has between 4 to 5 bars of boost on the indicator.

If you do not have these numbers then visit our section on improving the boost and signal

CHECK YOUR CEL-FI MODEL

Make sure you are using a model that supports your network:

Cel-Fi-P34-0/3/5/28xx = Telstra
Cel-Fi-P34-1/3/7/8xx = Optus or Vodafone

A carrier logo can usually be found on the back of the box or packaging box to determine if the unit supports Optus or Vodafone.

Can’t Make Calls or Calls Dropping

CHECK YOUR BOXES

The best way to determine the issue is to see what the boxes are doing when the call drop occurs or when a call cannot be made.

Ensure your Network Unit (large box) has a decent signal from the network of 4 to 5 bars.

Make sure your coverage unit (small box) has 4-5 bars of boost on the indicator.

If you do not have these numbers then visit our section on improving the boost and signal

If the boxes display an error go to our system error section.

If the link between the boxes is dropping and then reconnecitng all the time, then it could be caused by the boxes being on the edge of communication. If you have full bars, try moving the boxes closer so you get a bar less.

The other cause of the link dropping is radio interference in the building. If this is the case visit our radio interference section to find a solution.

CHECK PHONE SIGNAL

When the call drops or you cant make a call, check the phones signal strength, and also if you are using 3G or 4G on the call.

If you are using 4G when on a call, then in your phones settings turn off 4G to test if the same problem occurs on 3G. Some phone have settings that enable voice calls to only go via 3G.

If you have good 3G signal and still can’t make a call, then contact our technical department.

STAND CLOSE TO COVERAGE UNIT

The coverage unit is the only box that puts out the mobile signal.

Does the problem still occur when you place a call near the coverage unit? (small box)

If calls improve then the coverage area might need to be expanded by visiting our section on improving the boost and signal

CHECK YOUR CEL-FI MODEL

Make sure you are using a model that supports your network:

Cel-Fi-P34-0/3/5/28xx = Telstra

Cel-Fi-P34-1/3/7/8xx = Optus or Vodafone

A carrier logo can usually be found on the back of the box or packaging box to determine if the unit supports Optus or Vodafone.

Signal Only Short Distance From Coverage Unit

CHECK YOUR BOXES

In order to increase the signal spread of the coverage unit you need to maximise the boost.

Make sure your coverage unit (small box) has between 4 and 5 bars of boost on the indicator. The higher the better.

Ensure your Network Unit (large box) has a decent signal from the network of 4 to 5 bars if possible.

If you do not have these numbers then visit our section on improving the boost and signal

OBTRUCTIONS AROUND COVERAGE UNIT

The coverage unit is the only box that puts out the mobile signal.

Ensure that there are no obstruction around the coverage unit that may limit the signal spread. This could be metal objects, walls, your wife or barriers.

This box ideally needs to be in an open area. Network Unit won’t connect to the mobile unit

No Connection to Mobile Network

CHECK FOR SIGNAL ON YOUR PHONE

Go outside and check if you can receive a 3G and 4G signal? (you will need to turn 4G on and off to check)

Yes – check inside where you want to place the Network Unit (large box) for a mobile signal. It must be present on your phone in that spot otherwise the Network Unit will not find signal. The Network Unit requires a minimum of -104dB of 3G signal or -120dB of 4G signal to connect to the network.

No – check on the roof of the building. If you have signal up there you can install an external antenna to provide the Network Unit with signal. If a mobile signal is not present on the roof then Cel-Fi may not be suitable for your location.

Tip: We have instructions of how to get exact signal measurements on your phone for iPhone or Android models.

CHECK YOUR NETWORK UNIT

Ensure the screen on your Network Unit (large box) light up appears once powered up.

Next to the bars a 3G or 4G icon or both will be displayed indicating the technology you have signal for.

If the boxes display an error go to our system error section.

If there is a 3G/4G icon present, then the bars represent the 4G band. So if this is the case we need to check your 3G signal strength in the special ‘WAVE APP or nerd mode’ to see what is happening.

CHECK YOUR CEL-FI MODEL

Make sure you are using a model that supports your network:

Cel-Fi-P34-0/3/5/28xx = Telstra

Cel-Fi-P34-1/3/7/8xx = Optus or Vodafone

A carrier logo can usually be found on the back of the box or packaging box to determine if the unit supports Optus or Vodafone.

Error Message on Boxes

TOO CLOSE OR FAR APART

This pops up on the screen when the Network and Coverage Units are too far away to communicate with each other or too close to offer much boost.

I am sure you know what to do here.

HARDWARE ERROR OF DEATH

I have never seen this personally, but it is worth a mention.

It is a hardware error indicator, try restarting the unit mentioned on the screen and if it persists then contact our technical department.

NO SIGNAL MESSAGE

The Network Unit cannot receive a Signal from the network, or is unable to connect to a tower. Visit the Network Connection section on how to fix.

TOO HOT….TOO HOT!

One of the boxes is running too hot, this could be due to the weather, lack of ventilation or being in direct sunlight.

Try moving the box to a different location and ensure the vents are not blocked. This feature helps protect the hardware from failure, once cooled down the system will start again automatically.

SIGNAL TOO STRONG MESSAGE

The input signal from the mobile network is too strong to use a repeater. Too strong…..are you kidding me? Yes the signal can be too strong.

Try moving the Network Unit or the external antenna if using one to a different location.

If the error persists then contact our technical department.

OTHER ERRORS

You may come across a few other errors, which are detailed in the quick start guide.

Contact our technical department if you have any concerns.

Link Dropping Between Boxes

YOU HAVE INDOOR INTERFERENCE

The boxes are connected via a 5GHz radio link. If you have a device that transmits on this band then it could cause interference.

One of the best ways to check is to turn that device off and test if the link still drops.

Devices that could have the potential to cause issues:

WiFi Routers and modems

Smart TV’s

Wi-Fi Access Points

Cordless Phones

Media Centre Boxes

WiFi enables DVD Players

Baby Monitors

Wireless Doorbells

Audio/Video Senders

Microwaves

Wireless Cameras

Little white fluffy dogs

CEL-FI AND WI-FI ROUTERS LIVING IN HARMONY

The most common cause of interference is from 5GHz WiFi Routers.

Cel-Fi uses up to four channels within the 5GHz band and these can overlap with the channels used by 5GHz WiFi routers.

The good news is that these two devices can live in harmony by using these steps:

1) With the Cel-Fi boxes connected, turn off your WiFi Router and then power back on. Your router should then select vacant 5GHz channels.

2) If over time this does not fix the problem, then your router should have the ability to manually select channels. Try to select channel 149 (5735MHz) and above as Cel-Fi does not use these.

3) Another option is to turn off 5GHz and only use 2.4GHz on the router.

BOXES ARE TOO FAR AWAY FROM EACH OTHER

If you have a high number (5 bars) on the coverage unit, then the boxes could be on the edge of their communciation range.

If someone walks between the boxes, a ray of sunshine comes in during the afternoon, or the cat sits on one of the boxes the link could drop.

Move the boxes closer together and aim for one number less on the Coverage Unit than you already have.
