T-Mobile have today enabled HSUPA on their mobile data service nationwide which will boost upload speeds from the service to up to 1.4Mbps. This will allow users to send files such as photos or videos from their laptop or mobile faster than before. Most other networks currently use HSDPA which only offers an upstream speed of 384Kbps.
With this upgrade also comes the faster HSDPA downstream speeds which offer speeds up to 7.2Mbps. These HSDPA speeds are currently being deployed in the Greater London area (within the M25), with other major cities to follow later in the year.
The technology being used, High-Speed Uplink Packet Access, or HSUPA for short, is a 3G mobile technology that allows for even faster upload speeds with a maximum of 5.76Mbps which is expected to increase to 11.5Mbps in the future. HSDPA is also possible up to 14.4Mbps, with future upgrades (HSPA Evolved) bringing data rates of 42Mbps. These are of course just small steps on a path to an even faster future with projects like the 3GPP LTE expected to bring 100Mbps to the mobile broadband market. These speeds are of course theoretical maximums and are limited by signal strength, so the further from the mobile base station, the slower you will actually get.
