CEL-FI GO G43 is a professionally installed commercial solution for improving mobile coverage from up to three UK mobile networks. It is not sold as a fixed online bundle because the correct system configuration depends on the networks required, the usable signal outside the building, the building layout and the area that needs coverage.

Tell us about your site and the mobile networks you need to improve. Frequency Signal Solutions will assess whether G43 is the right CEL-FI solution, advise on the system design and provide an indicative proposal. Where required, we will arrange a site survey before the final system is specified and commissioned.

Improve Coverage for Up to Three UK Mobile Networks

CEL-FI GO G43 can be configured to improve coverage for up to three of the four UK host mobile networks: EE, O2, Three and Vodafone. Customers using mobile providers hosted on one of the selected networks can also benefit from the improved host-network signal where compatible.

 

The networks to be relayed are selected as part of the system design and commissioning process.

 

If only one network needs improving, CEL-FI GO G41 may be sufficient. For larger or more complex buildings, wider coverage requirements or projects requiring all four UK host networks, Frequency Signal Solutions can assess whether a CEL-FI QUATRA solution is more appropriate.

 

Not sure whether you need coverage for one network, three networks or all four?

 

Read our guide to multi-network mobile signal boosters for business to understand the options and find the right solution for your premises.

Remote Monitoring & Management

CEL-FI GO G43 can be monitored and managed through the Nextivity WAVE Portal. This provides authorised support teams with visibility of system status, configuration and performance after installation.

 

Frequency Signal Solutions can provide ongoing remote support and monitoring as part of the project where required.

Where CEL-FI GO G43 Fits

CEL-FI GO G43 is designed for smaller and medium-sized commercial sites that need reliable indoor coverage from up to three mobile networks. Typical applications include retail stores, restaurants, convenience stores, petrol stations and EV charging locations, branch offices, banks, clubhouses and similar commercial premises.

 

G43 is an off-air solution, so suitable mobile signal must be available outside the building for the networks that need improving. The external donor antennas capture that signal and the designed indoor antenna system distributes improved coverage inside the property.

 

Suitability is determined by the available donor signal, building layout, required networks and target coverage area rather than by building size alone. Frequency Signal Solutions can assess these factors before specifying the system.

Check Whether G43 Is Suitable
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.

Survey, Design, Installation & Support

Frequency Signal Solutions can manage the complete G43 project from initial assessment through to installation and ongoing support.

 

Our work can include signal assessment, site survey, system design, donor and coverage antenna planning, installation, commissioning, testing and ongoing remote monitoring.

 

The objective is not simply to install a G43 unit, but to specify the correct CEL-FI solution for the networks, building and coverage requirement.

The CEL-FI GO G43 Smart Signal Booster is a premium mobile phone signal booster that strengthens your 3G / 4G / 5G signal coverage. It is the most powerful carrier-grade solution available, delivering 100dB signal gain with the class-leading voice and data wireless performance. CEL-FI GO G43 is designed to solve cellular coverage issues for indoor environments and does not interfere with other wireless devices.
This solution is ideal for use in petrol stations, retail stores, restaurants, banks, clubhouses and other small businesses. How CEL-FI GO G43 Works CEL-FI GO G43 is an off-air mobile coverage system. External donor antennas capture usable mobile signals from outside the building and feed them to the G43. The system processes the selected operator signals individually before improved coverage is distributed inside the building through the designed server-antenna layout.
Because system performance depends on the available donor signal, antenna locations, cable routes and building layout, G43 is designed and commissioned for the individual site rather than supplied as a standard self-install bundle. Key Features
