From 1 July, T-Mobile will be the first operator to deploy HSUPA technology on a nationwide basis - meaning users across the UK will be able to upload documents, photos and videos at speeds of up to 1.4mbps, an improvement of up to fivefold on the current standard.
T-Mobile has also upgraded its HSDPA-enabled 3G network within Greater London to deliver maximum speeds of 4.5mbps.
"Mobile Broadband has come of age. Today, 25% of new contract customers are signing up and we expect to quadruple our user base in 2008. We knew mobile broadband would burst on the scene," said T-Mobile UK Chief Executive Jim Hyde.
T-Mobile has also upgraded the underlying download capability of the HSDPA-enabled 3G network to 7.2mbps, initially within the M25 but rolling out to other major cities during the second half of 2008. This will deliver maximum mobile broadband speeds of up to 4.5mbps in enabled areas.
