Long-term evolution

The idea of getting high speed, super-reliable mobile broadband from a cell tower to your laptop or phone via WiMAX is not quite dead in the water, but it's certainly in need of a bit of mouth to mouth.

Far from being the 'Next Big Thing' as it was touted a few years back, it's had a painful and traumatic incubation period, which has seen some US carriers begin to adopt it and, in fact, quite a few businesses use it for point to point communications, but public access has dwindled from trial areas to almost nothing.

Partly, this may be because the company which owns the licence to operate WiMAX licences in several cities, Freedom4, was recently bought out and the new owners aren't in any rush to monetise the technology. More likely, it's because the mobile phone companies are happy with the current HSPDA speeds and are betting on an alternative technology, which is known as 4G, or Long Term Evolution (LTE) to supply almost the same amount of bandwidth without completely reworking their networks for WiMAX.

Lucky Scandinavians living in Stockholm or Oslo with a TeliaSonera contract can already sign up for LTE, while O2 is planning on launching a 150Mbps LTE package in the UK some time this year. We don't expect WiMAX to give up without a serious fight, though.

In the US, mobile networks are beginning to fall over because of the volume of 3G traffic running over them, and WiMAX's new architecture could well be a way to increase capacity to cope with demand. In which case, expect to see it begin sprouting up everywhere.

Faster bits and bytes

Rather more prosaic than the technologies listed elsewhere in this article the internals of your PC are also being overhauled by the powers that be. There's a revision to the SATA standard out for disk drives, and USB 3.0 is appearing on motherboards to speed up the default peripheral connection.

They are big steps forward. SATA III doubles the bandwidth available to storage from a theoretical 3Gbps to 6Gbps, while on paper USB 3.0 is a ten-fold increase from 480Mbps to 4.8Gbps for cabled peripherals.

Motherboards sporting ports of both flavours are already available from most manufacturers. Although both technologies are much faster than their predecessors, neither is likely to have a huge impact on consumer PCs.

In the world of business where milliseconds are money, the upgrades may mean something, but for the likes of us, compatible drives and peripherals will be a while coming yet.
