Reliable Indoor 4G and 5G Now Enabled Across London Workplaces

Proptivity is reducing mobile dead spots to improve coverage in London workspaces through partnership with Telehouse Europe

London, UK – 24^th March 2026 – Telehouse Europe, a leading global data centre service provider, has partnered with Proptivity, a provider of shared mobile infrastructure for commercial buildings, to enable high-performance indoor 4G and 5G connectivity across London workplaces.

Through the partnership, Proptivity is using Telehouse’s London Docklands campus as its UK interconnection hub, enabling direct connectivity with UK mobile network operators and supporting the scalable deployment of indoor mobile infrastructure across commercial properties. This is already helping building owners and occupiers across the capital deliver the reliable mobile connectivity that shared office tenants and visitors expect inside modern workplaces.

As commercial buildings become more energy-efficient, mobile signals often struggle to penetrate internal spaces, leading to inconsistent coverage. The result can be dropped calls, patchy data, and the familiar experience of having to move around a building to find signal. Proptivity addresses this by building and operating shared in-building mobile infrastructure under a neutral host model, enabling multiple mobile network operators (MNOs) to deliver coverage through a single deployment.

By establishing its UK hub at Telehouse’s London Docklands campus, Proptivity has been able to interconnect with UK MNOs and extend services to enterprise buildings across the city in a consistent and scalable way. This is increasingly important as organisations balance hybrid working, and as property owners look to make workplaces more connected, productive, and attractive to tenants.

Will Scott, Vice President of Sales, Telehouse Europe, said: “Telehouse’s London Docklands campus sits at the heart of the UK connectivity ecosystem, and we are pleased to support Proptivity’s rollout. By providing a resilient interconnection environment with secure facilities and on-site support, we are helping deliver reliable mobile service across commercial buildings for the people who use them every day. That matters because businesses now see dependable mobile coverage as a basic requirement of office space.”

In addition to interconnection, Telehouse is supporting Proptivity with fibre-delivered, highly accurate timing sourced from the National Physical Laboratory (NPL), ensuring precise synchronisation for indoor 5G deployments. Accurate timing is essential to high-performance 5G. In commercial buildings, where rooftop satellite antenna installations can be complex or impractical, fibre-based timing provides a resilient and scalable alternative.

Magnus Kelly, Director, Proptivity, said: “With Telehouse’s support, we are delivering highly accurate timing to our indoor 5G systems in London. This precision is critical to ensuring consistent, high-quality mobile performance inside buildings, allowing people to use their phones seamlessly when they are in the office.”

Elena Parsons, Commercial Manager for Timing Services at NPL, said: “NPL maintains the UK national timescale and makes highly accurate, traceable time available to industry. For indoor 5G sites where rooftop GNSS is difficult, fibre-delivered timing provides a practical alternative and an additional layer of resilience, helping networks remain stable even if satellite timing is disrupted.”
