Indoor Mobile Coverage Solutions
Poor indoor mobile signal isn't a network problem — it's a building problem. We solve it with a professionally designed, Ofcom-compliant digital repeater system tailored to your premises.

Modern offices, warehouses, and commercial buildings often significantly reduce mobile signals entering the building. Materials such as concrete & steel reinforcement, foil-backed insulation, energy-efficient (low-E) glass, and metal cladding reflect or absorb radio waves — preventing outdoor coverage from reaching inside.
In larger buildings, signal also weakens further as it passes through walls, floors and internal structures. Strong outdoor signal does not guarantee indoor coverage.
Dropped Calls
Unreliable voice quality and patchy data across floors and rooms.
Slow Data
Apps and devices struggle to stay connected. Staff waste time hunting for signal.
Operational Impact
Affects staff productivity, visitor experience, and systems relying on mobile connectivity — IoT, alarms, mobile payments.
How We Improve Indoor Mobile Signal
Capture & Process
High-gain external antennas capture the available outdoor signal. A digital system then filters, controls and stabilises the supported network signals for safe indoor distribution.
Intelligent Distribution
Balanced, stable coverage is delivered across the building via discrete indoor antennas — placed exactly where signal is needed, from basement through to top floor.
Tailored Design
Coverage is designed specifically for each building, mapped to your layout. No two installations are the same.
- Reliable voice calls in previously weak areas
- Stable mobile data for staff and visitors
- Support for devices relying on mobile connectivity
- Extended coverage in areas where signal was previously unusable
Why a Digital Booster Works Better
Not all signal boosters are equal. A digital repeater selects and balances signal per frequency band — rather than simply amplifying whatever is available. This prevents the instability and interference common with analogue systems, and ensures consistent performance across all supported networks.
Digital Repeater
Processes and controls signal per frequency band to maintain stable, usable coverage indoors.
- Smart self-regulation
- 100% digital filtering
- No interference risk
Analogue Repeater
Amplifies whatever signal is available — but does not optimise it. Can cause interference on surrounding networks.
No Repeater
Signal stays weak, patchy and unreliable. Coverage gaps persist across floors and rooms.
The MultiBoost System
The MultiBoost is a professional-grade digital signal repeater, designed and manufactured in Europe with over 35 years of RF engineering experience, and deployed in the UK by GW-Tech. It uses passive coax distribution — meaning no power is required at each indoor antenna point, keeping installation clean and straight forward.

How We Work With You
Free Remote Signal Check
Share your building address. We review network coverage data for your location at no cost and with no commitment — confirming whether sufficient outdoor signal exists to support an indoor system.
Building Discussion & Budget Estimate
We discuss your building layout — floors, areas needing coverage, and access considerations. We provide a preliminary budget estimate covering equipment and installation, before any commitment.
On-Site Survey & Fixed Quotation
If the estimate works, we carry out an on-site survey and provide a fixed quotation. If you proceed, 50% of the survey fee is credited against the final invoice. If not, the survey fee is invoiced separately.
Installation & Handover
Equipment ordered, installation scheduled and delivered by experienced data cabling professionals. System commissioned, tested and documented before handover. Remote monitoring included.
