For those who came in late, Cat 9, or Category 9 4G, is the latest network capable of supporting 450Mbps download speeds, and devices such as HTC M10, or the Samsung Galaxy S7 are capable of achieving these speeds if they pace themselves and train hard.

EE CEO Marc Allera said there was no point having the latest smartphones on a network that can’t support the top speeds the device is capable.

“We’ve invested in our network to ensure that all of our customers get the most out of the amazing smartphones they have, and can keep up with the highest speeds that the latest devices offer. With 4G+ now supporting Cat 9 devices, plus Wi-Fi Calling and 4G Calling, customers on EE will continue to get more from their new smartphone than on any other network in the UK.”

EE has achieved these speeds adding 20MHz of the 1800MHz spectrum to the 35Mhz of the 2600MHz spectrum, the company said. After baking in a moderate oven for 30 minutes this created the 55MHz of spectrum, deployed for 4G services. The telecom also said it is improving indoor coverage by switching on more than3,500 sites with low frequency 800MHz spectrum.
