PURELIFI LIMITED

Their core work

pureLiFi is a Scottish SME that develops Light Fidelity (LiFi) technology — wireless data transmission using light rather than radio frequencies. They provide optical wireless communication components and systems for integration into networking architectures, from aircraft cabins to 5G private networks. Their work spans the full LiFi stack: physical-layer visible light communications, energy-efficient IoT connectivity, and integration of optical wireless with cellular and WiFi in multi-band network environments. They are one of the few commercial companies globally focused exclusively on bringing LiFi from research to market.

What they specialise in

How they've shifted over time

pureLiFi's early H2020 participation (2017) focused on sector-specific applications — aircraft cabin communications (ALC), railway asset management (IN2DREAMS), and raw terabit-speed optical/radio links (WORTECS). From 2019 onward, their focus shifted decisively toward integration into 5G and beyond-5G network architectures, private networks, multi-tenancy, and AI-powered network management. The trajectory shows a company moving from "LiFi as a standalone technology" toward "LiFi as a native component of next-generation telecom infrastructure."

pureLiFi is positioning LiFi as a standard building block within AI-managed, multi-band beyond-5G networks — expect them to pursue projects combining optical wireless with private 5G, edge computing, and smart infrastructure.

How they like to work

pureLiFi always participates as a partner, never as coordinator — consistent with their role as a specialist technology provider contributing a specific capability (LiFi) to larger consortia. With 64 unique partners across 16 countries in just 6 projects, they work in large, diverse consortia rather than small focused teams. This broad network suggests they are easy to integrate into new partnerships and bring a well-defined, non-overlapping technology contribution that complements rather than competes with other partners.

Extensive network of 64 unique partners across 16 countries built through 6 projects, indicating they consistently join large European consortia. Their Edinburgh base and participation in Clean Sky 2, Shift2Rail, and ICT programmes suggest strong connections to both transport and telecom research communities.

What sets them apart

pureLiFi is one of very few companies in Europe — and globally — commercializing LiFi technology. This makes them an almost irreplaceable partner for any consortium that needs visible-light communication expertise. Their ability to bridge transport, telecom, and IoT applications with a single core technology gives consortium builders a versatile specialist who brings genuine differentiation to proposals.

Highlights from their portfolio
