4G rollout: 'Speeds could be 20 times faster'

11 September 2012 Last updated at 10:09 BST

Mobile operator Everything Everywhere (EE) is widely expected to unveil the UK's first fourth generation (4G) phone service shortly.

The operator has issued invitations for a press event to announce the "latest innovation in network technology".

The event is thought to concern 4G because 11 September is the first day regulator Ofcom said EE could offer such services.

Technology expert Paul Vlissidis discussed the likely impact of 4G technology on BBC Breakfast.
