UKTIN is the innovation network for the UK telecoms sector, bringing together industry, academia, and government to catalyse telecoms R&D investment, cooperation, and commercialisation. Founded in 2022, it is delivered by a consortium of four partners - Digital Catapult, Cambridge Wireless, University of Bristol, and WM5G - who draw on their distinct strengths in a collaborative approach. UKTIN has been initially funded by the Department for Digital, Culture, Media & Sport (DCMS) to drive the 5G Supply Chain Diversification Strategy and it will provide support for supply chain diversification in UK telecoms. It will work towards this goal by strengthening UK capabilities in open telecoms, attracting overseas companies and talent, facilitating indigenous supply chain development, catalysing public and private investment, and proactively promoting UK capability internationally.
