More on HSDPA for Laptops

Last week Dell announced its plans to embed Vodafone's 3G wireless broadband technology in notebook PCs sold in the UK, France, and Germany which is expected to release in the first half of this year. This High-Speed Downlink Packet Access (HSDPA) capability boost the 3G dataspeeds by approx 4 times. This news becomes significant with respect to announcements of HSDPA connectivity based on the usual data card form factor that we are used to seeing with 3G and GPRS.

Basically, it is an upgrade to existing 3G networks that were originally built out in Europe based on the UMTS (Universal Mobile Telecommunications System) standard. 3G networks upgraded to HSDPA are anticipated to deliver three to four times the data capacity and three to four times the data access rates of UMTS.

HSDPA also significantly reduces network latency, the delay associated with response to network requests, which further boosts the performance of bandwidth consuming applications such as Web browsing over HTTP. Together with better in-building coverage and improved QoS management, the end result should be a dramatically enhanced user experience, and a network that is able to tolerate high network loads at busy times much more effectively.

HSDPA rollout is set to gain momentum as we go through the second half of the year, though timescales vary between operators and indications are that it will take some time before 3G networks are fully upgraded. From that point onwards, new cell sites commissioned as the physical 3G networks continue to expand will be HSDPA enabled. In terms of HSDPA coverage, we can expect the kind of rollout schedule we have seen before with 3G - specific cities and major conurbations first, with wider coverage following. In reality though, it is likely to be well into 2007 before we see anything other than relatively restricted HSDPA availability.

The obvious question therefore is why anyone would be interested in buying a notebook from Dell with embedded HSDPA as soon as the middle of this year. The answer is to future proof their investment. The modules installed by Dell will support UMTS and GPRS (2.5G) as well as HSDPA. They may therefore be used to connect via the commonly available cellular data standards today, while being ready to take advantage of HSDPA as coverage increases to useful levels, as it undoubtedly will during the lifetime of a new PC bought this year.

So get ready and gear up for higher wireless data speeds.

But it will take sometime to get 3G in full level. We need to wait till then to have a complete technological usage.
