Four new Bluetooth low energy chips announced at Developer’s Preview

At a packed conference hall in Tokyo today, the Bluetooth SIG hosted the first public demonstrations of the new Bluetooth low energy standard to an audience of press and consumer electronics companies. This new standard will enable a wide range of connected devices to communicate with and through mobile phones. Four new chips were announced at the all-day event – a sure sign of gathering momentum.

The exciting aspect of Bluetooth low energy is its ability to enable low cost devices to be made that can send their data all of the way to the web. It’s based on over ten years of experience and promises to have the fastest growing ecosystem of any wireless standard. Today’s meeting sent a clear message to developers that they need to start designing now to be ready for the first generation of Bluetooth low energy handsets.

Shakeout in Short Range Wireless suppliers gains momentum

Last week’s announcement that the IP behind Meshnetics’ ZigBee stack is being acquired by Atmel underlines the continuing consolidation of the short range wireless industry. Since the boom in short range wireless that was started by Bluetooth and Wi-Fi there has been a growing number of VC funded silicon and stack companies entering this market space. It has been obvious for some time that the number of companies is not sustainable and that at some point the bubble would burst. The sale of Zensys to Sigma heralded the start of the process. 2009 will be the year when momentum builds and a lot more wireless dreams hit the buffers.

2009 – The year of Bluetooth low energy

This year will see the arrival of a new short range wireless standard that is set to revolutionise the way that devices are made. That’s not a new claim – I recall it being made for Bluetooth, Wi-Fi, ZigBee, Home-RF and DECT, amongst others. Some succeeded massively, some struggled on and some failed. This year sees another technology join the fold and I’m confident that it will make a bigger change that any that has preceded it.

The technology I’m talking about is called Bluetooth low energy. Don’t be fooled by thinking it’s a variant of Bluetooth – that would be a mistake. Although it’s part of the Bluetooth family of standards, and designed to coexist within an existing Bluetooth chip, it’s a totally new standard, designed from the bottom up to fulfil a new set of requirements.

Those requirements are to enable a new generation of products that can connect to mobile phones. It covers everything from fashion accessories, watches, fitness and medical devices to office and security products. The essential thing is that they can be low power, low cost devices that only need to send small amounts of data. That allows them to be run off batteries that don’t need regular charging. In fact most of them will run for years on single coin cells.

As well as connecting to your phone as accessories, they’ll also be able to use the phone to send their data over your mobile network to a remote web service. That’s where Bluetooth low energy becomes really powerful, as it allows your mobile phone to act as a gateway.
