Britain's BT Group plans to launch 5G services this autumn and will make it available to all mobile users in the busiest parts of 16 cities by the end of the year.

This comes weeks after BT-owned EE, the country's biggest mobile operator, announced in May that it would be the first company to launch 5G services in the country, beginning in six cities, including London, from the end of May.

BT Plus customers will be the first of its mobile customers to benefit from the option to upgrade to 5G, BT said, adding that this would make BT the first provider to offer 5G as part of a converged mobile and broadband package.

BT Plus is Britain's first converged fibre and mobile plan, the country's biggest broadband and mobile provider said.

5G will be available in the busiest parts of London, Birmingham, Manchester, Edinburgh, Cardiff, Belfast, Glasgow, Newcastle, Liverpool, Leeds, Hull, Sheffield, Nottingham, Leicester, Coventry and Bristol by the end of 2019, the former telecoms monopoly said.
