Project Overview
Simpli-Fi was appointed to deliver a reliable indoor mobile coverage solution at the Harworth Building – the headquarters of Harworth Group, one of the UK’s leading land and property regeneration companies.
This high-spec office space required seamless mobile signal throughout to support day-to-day operations and ensure a consistently strong user experience for staff and visitors alike.
The Challenge
Like many modern buildings, the Harworth Building utilised energy-efficient materials and construction techniques, which, while beneficial for sustainability, often hindered mobile signal penetration. Staff were experiencing poor signal strength in certain areas of the building, which impacted productivity and created frustration for both employees and guests.
Harworth Group recognised the need to resolve this issue as part of their commitment to providing a smart, future-ready workplace environment.
Our Solution
Simpli-Fi designed and installed a bespoke indoor mobile coverage system tailored to the unique layout and usage patterns of the building. From initial site survey and signal testing through to deployment and final optimisation, we worked closely with all stakeholders to ensure minimal disruption to the working environment.
Our solution ensures reliable coverage for all major UK mobile networks throughout the building – including offices, meeting rooms, shared spaces, and lift areas – ensuring staff stay connected wherever they are.
The Result
The project was delivered on time and with zero operational downtime for the business. Harworth Group now benefits from:
- Strong and consistent mobile coverage across the entire building
- A more connected and productive workplace for staff and visitors
- Future-ready infrastructure to support growth and evolving tech needs
