HSUPA is here

T-Mobile recently launched HSUPA network here in UK:

T-Mobile said, in certain areas, upload speeds will be five times faster than previously. It claims upload speeds of up to 1.4 Mbps. T-Mobile UK chief executive Jim Hyde said: "Mobile broadband has come of age. Today, 25 per cent of new contract customers are signing up and we expect to quadruple our user base in 2008.

"We knew mobile broadband would burst on to the scene and our continued investment in new technology is paying dividends for customers seeking a fast, consistent service which offers great value."

T-Mobile has also upgraded its HSDPA network, it said. It now boasts download speeds of up to 7.2Mbps within the M25.

Meanwhile, T-Mobile Germany has annoucned the completion of the HSPA upgrade to it's 3G network, meaning that customers can now download (HSDPA) at 7.2Mbps. The plan is that the upload speed (HSUPA) will be boosted to 2Mbps by the end of the year.

In other news, AT&T in USA plans for 2008 include the completion of the nation's first High Speed Uplink Packet Access (HSUPA)-enabled network by the middle of the year. The AT&T 3G network now delivers typical downlink speeds ranging between 700 Kbps (kilobits per second) and 1.7 Mbps (megabits per second), and it will now offer faster uplink speeds ranging between 500 Kbps and 1.2 Mbps. The faster uplink speeds allow AT&T's HSUPA-enabled laptop users to quickly send large files and take full advantage of the latest Internet and business applications.

An article in TelecomTV claims that Mobile Social Networking may be the killer application for the promised HSUPA:

This is the year for HSUPA, or High-Speed Uplink Packet Access, according to leading provider of the enabling technology, Qualcomm. HSUPA is the companion standard to HSDPA (the high speed downlink standard) and enables 3G users to upload large files - especially still photos or videos - in seconds rather than minutes.

Qualcomm says that while HSUPA used to be allocated only to the high end chipsets (for use on high end phones) it's now being included as standard for chipsets aimed at 'mid range' devices and by the end of the year will appear as standard on low end phones as well.
Why the adoption spurt? Mobile social networking and user generated contents are the main reason. Where many traditional data applications, such as receiving email, web browsing, and music and video downloading are overwhelmingly asymmetric (far more data coming down than going up) the coming mobile social networking wave looks likely to demand huge amounts of uplink capacity as users begin to use the features of their new upscale phones in earnest. High resolution multi-megapixel cameras mean big, chunky picture files; easy video capture means even larger video files; and new applications involving pictures and location, via GPS, require high quality, reliable connectivity back to the controlling server.

According to Qualcomm, mobile social networking will finally and resoundingly answer the question: Why do we need 3G?

We'll need it because the evidence shows that users are interested in taking social networking out of the confines of the tethered PC, and putting it on the road via their mobiles where it can blend with and enhance real, physical, non-virtual social networking: the sort which involves real people moving about and doing things in real places.

So users are fast moving beyond SMS and towards applications and services which will enable them to really share their activities at, say, live events.

So let HSUPA roll and let the fun begin.
