Creative Connectivity

What’s the value of ZigBee?

Today NXP announced that it is acquiring Jennic, the UK based RF design company that specialises in ZigBee chips and stacks. That in itself is not surprising. The market for ZigBee silicon has been consolidating for some time, with the previous acquisitions of One RF, Chipcon and module vendor Meshnetics. It’s something that I predicted would happen last year. It’s good news for the design team at Jennic, as NXP should provide them with the scale to grow and a sales infrastructure and industry stature that increases their customer base.

However, one aspect of the deal is likely to send shockwaves through the industry. That’s the price tag for the acquisition, which is $12.2 million. Compare that to the value that TI paid for Chipcon in 2005, which was around $200 million.

ANT runs scared as Bluetooth low energy appears

It’s always interesting seeing how industries react to new entrants. ANT has been having a successful time in persuading sports and fitness manufacturers to use its standard for wireless connectivity. That’s partly because it does what it says on the tin and partly because it’s not had a lot of competition.

This week, following the launch of Bluetooth low energy, the FAQ on the ANT website makes the strange claim that once Bluetooth low energy becomes available in mobile phones, ANT devices can take advantage of a bridge in watches to talk to phones. It’s difficult to understand what, other than desperation at the advent of real competition, is driving them to say that. It’s like telling vegetarians that you have a cunning plan which will enable them to eat meat.

Bluetooth low energy – aiming for the trillions

Today the Bluetooth SIG formally adopted the full specification for Bluetooth low energy and made it available for public download. It’s exciting – they’re firing the starting pistol for a new ecosystem of innovative products and applications that will change the way we think about the things around us.

Bluetooth low energy is not just a variant of the existing Bluetooth specification – it’s an entirely new standard that’s been optimised for low power and internet connectivity. It marks a step change in short range wireless, providing a new short range connection for a new decade.

Smart Metering – the next Y2K bonanza?

At a number of smart metering and smart grid conferences that I’ve been attending recently, it’s be interesting to note the number of fifty and sixty-something consultants who are looking suspiciously like cats who are overdosing on cream. What has brought the smiles to their faces is their belief that the rush to deploy smart meters is considerably ahead of any solidification of standards, or even an understanding of what to do with them. That means that there will be lots of work to try and make the current generation of meters work, only to do it all over again in five years time, when the industry finally decides what the standards should be. If that’s how it pans out, then smart metering may pay their pensions in the same way that Y2K worries provided a happy retirement for a previous generation of engineers. It might be in their interest, but it’s a game-plan that is definitely not in the best interest of the industry.

Within the more general subject of smart grid, media coverage is centring on smart meters and the impact they will have on the consumer. That’s resulting in some aggressive battles between competing standards groups, a growing level of negative publicity for utilities that are being portrayed as greedy ogres trying to get more money out of the consumer, and the appearance of ever more flamboyant futurologists who believe that the utilities will control all of the appliances in our homes.

That level of noise has the effect of making smart meters look as if they are the lynchpin of the smart grid. Hence every utility is rushing to deploy them, backed by willing legislators showering them with stimulus funds. It’s not difficult to see why we’re in this topsy-turvy state. Underlying improvements to the grid don’t have a direct impact on consumers, or only do when the lack of them means that the consumer’s power disappears. Which makes it boring. In contrast, home automation offers the science fiction vision of devices that turn themselves on or off to minimise our energy bills and save the world. But does it help the industry?

The need for Patient Accessible Medical Records

I came across an excellent report on homecare and chronic disease management this week, produced by Pam Garside of the University of Cambridge for Healthcare at Home. Entitled “Lessons from the US” it looks at homecare practice in the two countries. Healthcare at Home are a commercial organisation with an interest in promoting home care (which you probably guessed from their name), but the report seems to be refreshingly clear independent.

It compares and contrasts the use of remote monitoring technology in the US and UK to support patients at home, both in terms of release from hospital and to manage long term chronic conditions. Its main conclusion is that the UK is far better positioned to benefit from this than the US. But there’s one proviso – that the UK needs to put in place a system that allows patient records to be shared between those involved in care, including the patients themselves.

The report acknowledges that this is currently lacking in the UK, but predicts that this will be remedied during the course of 2010 by the introduction on Summary Care Records (SCRs).

Pam’s obviously not spoken to the British GP’s Council. This week their chairman – Laurence Buckmann, made a presentation to the Local Medical Committee’s Conference calling for SCRs to be scrapped, ostensibly because they require a patient to opt out, rather than opting in. It’s part of an ongoing campaign against SCRs by the British Medical Association (BMA) that makes Luddites look progressive. And which seriously threatens innovation within the NHS.

Who owns Smart Energy?

There’s a lot of debate within the industry about who owns Smart Energy. Is it the utilities? Is it the consumer? Will it be Google? Until now, nobody has spotted who the real owner is, but at last it can be revealed – it’s the ZigBee Alliance. They quietly trademarked the phrase “Smart Energy” in the US last December. So if you make any Smart Energy product using any form of wireless, it may be time to get your cheque book out.
