The next generation of mobile technology - 5G - will be rolled out from 2019. It will enable faster streaming on our mobile phones and tablets and speed up the 'internet of things', allowing thousands of computers to 'talk' to each other. The fifth generation mobile network also has applications that could be used in public safety and healthcare. But will the UK build the infrastructure - installing more fibre and small communications masts - to benefit from this new technology? Joining Evan Davis for the debate will be:

Derek McManus, Chief Operating Officer at Telefonica UK, which owns O2.
Professor Dimitra Simeonidu, Director of the Smart Lab at Bristol University
and Kyle Brown, Head of Technology at Samsung Electronics.
