Indoor Mobile Coverage Solutions — GW-Tech

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.

The Problem

How Buildings Act Like a Faraday Cage

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.

How buildings weaken mobile signal

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.

The Solution

How We Improve Indoor Mobile Signal

1

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.

2

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.

3

Tailored Design

Coverage is designed specifically for each building, mapped to your layout. No two installations are the same.

Indoor antenna distribution across building floors
  • 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
Technology

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.

MultiBoost vs No Repeater vs Analogue Repeater signal comparison
Recommended

Digital Repeater

Processes and controls signal per frequency band to maintain stable, usable coverage indoors.

  • Smart self-regulation
  • 100% digital filtering
  • No interference risk
Partial Solution

Analogue Repeater

Amplifies whatever signal is available — but does not optimise it. Can cause interference on surrounding networks.

No Solution

No Repeater

Signal stays weak, patchy and unreliable. Coverage gaps persist across floors and rooms.

The Equipment

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.

Our Process

How We Work With You

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

Installation & Handover

Equipment ordered, installation scheduled and delivered by experienced data cabling professionals. System commissioned, tested and documented before handover. Remote monitoring included.

Legal & Regulatory

Compliance & Legal Operation

Mobile signal repeaters are regulated in the UK. Using non-compliant equipment or incorrect installation can cause interference and may result in enforcement action by Ofcom.

All equipment and installations must meet Ofcom Interface Requirement IR 2102 — including oscillation monitoring with safety shutdown and uplink switch-off.

We deploy compliant multi-operator systems with controlled signal management. Each installation is configured, tested, and documented to confirm compliance.

Ofcom VTS Compliant — Legal Multi-Operator Use

Why Compliance Matters

  • Legal to operate on all major UK networks
  • No interference with the wider mobile network
  • Supported by Ofcom as a registered provider
  • Documented installation confirms your compliance
  • Ongoing monitoring maintains regulatory standards
