Bluetooth Low Energy rides the Wave at Electronica

Electronica only comes every other year but it’s still the biggest electronics trade show in the world. The last time it ran, Bluetooth low energy was still better known as Wibree. In the intervening two years half a dozen companies have announced chips and the standard has been completed and published. So visitors to Munich last week had the first major opportunity for to see just how much progress has been made.

It’s obvious that the industry has moved from PowerPoint presentations to reality. Chips were on display, along with development boards and the first few modules. In the Forum within Electronica there were sessions on the applications it will enable, and in the adjoining Wireless Congress a full day’s track was devoted to developer training and further applications.

The silicon and tools are definitely here. Now it’s time for developers to add their imagination.

All I want for Christmas is Smart Energy

Have the girls and boys who have been working hard to make Smart Energy happen been good this year? Will Santa bring them what they want? It’s looking less than likely. Despite promises that specifications would be complete, progress has inevitably slipped. What’s worse, the elves in some of the utilities didn’t pay attention to the lists the boys and girls stuck up their chimneys last year, and instead of sending them energy savings, it turns out that they actually sent them higher utility bills.

Of course, things were never going to happen as quickly as projected, even with the amount of stimulus money being thrown at the companies involved. If anything that’s resulted in things slowing down as everyone has concentrated on scrabbling around for a part of the pie, insisting that their toys are better than anyone else’s, and that they deserves the biggest box under the tree.

However, the story of the year is probably the level of consumer resentment that has built up towards smart metering deployments. Much of that seems to have been unnecessarily self-inflicted. In the Netherlands we’ve seen programs delayed because of privacy issues, and in the US there has been major customer resentment at higher bills. And that’s before we get into the ridiculous paranoia about the meters irradiating the population.

It’s interesting to contrast what’s happening within the UK. Not only are they taking a lead in deployment of real smart metering, with British Gas’ decision to roll out 2 million gas and electricity meters. There’s also the UK Government’s highly detailed consultation and a growing level of consumer education. It will be interesting to see whether that results in more customer satisfaction, and a bigger change in energy usage? That level of up-front education may be the most significant initiative of all the Smart Energy deployments that are happening around the world.

Ten Wireless Standards, Sitting on the Wall…

The Smart Metering industry is deperate to decide on a standard for short range communication. The UK Goverment has rushed through its consultation with a deadline for a technical standard by the end of next year, and in the US, SGIP’s PAP02 group wants to do it even faster. Whilst we need to start deploying devices, it concerns me that there’s a rush to make decisions with very little consideration of the relative merits of the different contenders.

There’s no shortage of contenders. At the last count I came across ten short range wireless standards that all think they should be the winner. Those include Bluetooth, Wi-Fi, ZigBee, Wavenis, Dash7, wireless MBUS, wireless KNX, DECT, Z-Wave and Bluetooth low energy. And they’re just the industry developed standards.

What worried me even more than the obvious rush was a off-hand comment made in a European standards meeting that I attended earlier this year. One of the people responsible for deciding on a common standard for Europe made the comment that “we’re not going to give any time to industry standards”. The subject of her venom was ZigBee, but it’s a charge that I’m increasingly hearing levelled at all of the “industry” standards. It appears there’s a perception amongst members of the older established Standards Development Organisations (SDOs) that because industry standards have not been produced by their traditional specification process, they’re not as good. That’s a very dangerous approach to take.

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.

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?
