Networks This G41 Can Boost

CEL-FI GO G41 can be configured for EE, O2, Vodafone or Three and will also support mobile providers that use the selected host network. A G41 boosts one host mobile network at a time.

 

If a commercial site needs more than one host network improved at the same time, contact Frequency Signal Solutions before choosing the equipment. Depending on the building and coverage requirement, CEL-FI G43 or QUATRA may be the more appropriate solution.

Future Proof - Your Investment is Protected

Whilst the G41 can only boost one main network at once, unlike other units you don’t need to buy a new unit if you change network in the future.

 

Simply use the Wave app (which you will need to download during installation) and you can easily change the settings within a few seconds.

Is This G41 Configuration Right for Your Site?

This configuration is designed for buildings where little or no usable mobile signal is available indoors but a usable donor signal can be found outside. The external directional antenna captures that signal and feeds it to the G41 before the improved signal is distributed inside the building.

 

If usable signal is already available inside the building and the problem is weak or inconsistent coverage elsewhere, the internal-antenna G41 bundle is usually the simpler option.

 

For a commercial building, we can assess the outside signal, antenna position, cable route, building layout and required coverage and confirm whether G41, G43 or QUATRA is the appropriate CEL-FI solution.

Ofcom Legally Compliant

CEL-FI boosters are compliant with Ofcom’s new licence-exempt requirements (IR2102) and legal to use in the UK.

 

CEL-FI solutions are also licence-exempt under ComReg requirements for Ireland.

 

The Specific Absorption Rate (SAR) is comparable to that of a smartphone, making them equally harmless to human health and the environment.

What's Included
  • 1x CEL-FI GO G41 Signal Booster
  • 1x CEL-FI Wideband Directional Antenna
  • 1x CEL-FI Wideband Indoor Omni Antenna

Installation Options

CEL-FI GO G41 can be self-installed, but commercial sites may benefit from a signal assessment and professional installation. For this external-antenna configuration, a usable donor signal must be available outside the building. Frequency Signal Solutions can assess donor signal, external antenna position, cable route, building layout and required coverage before installation.

  1. Install the external CEL-FI Wideband Directional Antenna
  2. Install the CEL-FI Wideband Indoor Omni Antenna
  3. Mount the CEL-FI GO G41 unit near a power outlet
  4. Connect the antennas to the unit (10m cables included)
  5. Finally plug in the CEL-FI GO G41 and monitor/optimise using the WAVE App
Need Professional Help With This G41?

For commercial buildings, Frequency Signal Solutions can survey the site, specify the correct antenna configuration, install the system and provide ongoing support. If the project needs multiple mobile networks or wider coverage, we can also advise whether G43 or QUATRA is more appropriate.

An external donor antenna collects the best mobile signal from outside and transmits it to a mobile signal booster unit. The unit strengthens the signal and rebroadcasts it inside the building via internal donor antennas.What is Included in the Bundle?
