O2 announced that it will be the public and private network provider of 5G connectivity for the testing and development of Connected and Autonomous Vehicle (CAV) technology at Millbrook Proving Ground in Bedfordshire.

O2 will enable 5G connectivity to Millbrook testing facilities from June 2019, using its 2.3 GHz and 3.4GHz spectrum in advance of the first phase of its 5G rollout in Belfast, Cardiff, Edinburgh and London later this year.

The on-site network consists of 59 sites and 89 small cells and is operated by British wireless solution provider Dense Air. Under a 12-month agreement with the AutoAir project, O2 will integrate the sites and small cells into its public infrastructure.
