ZigBee Energy Management and Sensor Centric Applications

  2. 2. 2 sensing something big Anyone with even a remote connection to the short-range wireless industry will know that wireless sensors and controls are the current preoccupation of legions of engineers, developers and marketeers. If we are to believe the hype, the success that has been seen so far for technologies such as Bluetooth, ZigBee, EnOcean, NFC, RFiD, etc, etc, is as nothing compared to the opportunity presented by wireless sensors and controls. Consumers may have bought a lot of Bluetooth headsets, and there are an awful lot of wireless chips in games consoles, cars, phones, but apparently, when we move into the M2M market, the health and fitness markets, smart homes/smart grids, the numbers are set to rise exponentially. Every man and his dog is claiming that he has the perfect solution. Well, every technology alliance and every individual wireless company is anyway. But which will prevail? To which fence should we nail our colours? And where should we put our hard-earned money? Incisor is uniquely positioned (a cliché as well worn as these trainers I’m wearing at the moment) to find out. We have relationships with pretty much all of the players. It was about time, then, that we reviewed this market. We put the word out that this special issue was to be published, and the response was, let’s say, enthusiastic. I can’t promise that the submissions here are entirely hype-free, but our contributors understand that there is only so much over-blown marketing bilge they can get away with then talking to readers that are as wireless market savvy as Incisor’s. You will have to judge for yourself which story carries most credence, and Dean Gratton has made his own, independent observations. Finally, Incisor.TV attended the Bluetooth SIG’s All Hands Meeting. If you really, really want to know what is going on inside the Bluetooth SIG, but couldn’t make it to Budapest, then watch the Incisor.TV movies in this issue.

  7. 7. 7 wireless sensors and controls – special feature section How smart are we being in our quest for smart metering? Richard Traherne, Cambridge Consultants. By Richard Traherne Head of Wireless and Commercial Director There’s no question that energy is firmly on the political agenda. The EU2020 energy targets, developed to tackle climate change, have now been approved by most European countries. They aim to reduce energy consumption and greenhouse gas emissions by 20% in the period from 1990 to 2020, with the UK government in fact targeting an overall reduction in greenhouse gas of 80% by 2050. This has arguably been the most significant driver for the roll-out of an advanced form of metering, known as ‘smart metering’, across Europe. Smart meters will be a component within an overall infrastructure that will enable us to consume our finite energy resources in a more intelligent manner. Already, initiatives such as micro-generation, electric vehicles and smart appliances are well underway to play their part in this future panacea. Against this backdrop, wireless technology is poised to be an essential ingredient in the solutions that enable this future generation of A potential UK smart infrastructure energy infrastructure. With one of the largest independent wireless development teams in metering cannot be considered alone; smart countries the meters are owned by the grid the world, Cambridge Consultants has appliance and smart grid solutions must be operator, whereas in others they are owned by developed a range of wireless solutions over created, for all geographical locations the energy suppliers. This has a big impact on the years for the energy sector and is now required. In particular, issues related to funding sources for the overall system, its very active in the area of smart metering, as it standardised interfaces (to create inter- architecture, as well as to the security and is known today.

  9. 9. 9 wireless sensors and controls – special feature section Wireless sensors and networks – the compliance web Joe Lomako, TRaC unravelled! By Joe Lomako, Business Development Manager, TRaC Wireless technology has become an integral part of everyday life. It is almost impossible to go through a single day without using any wireless device in some aspect of your daily routine. It is everywhere; in all manner of products and with varying degrees of complexity and security. This is particularly the case in the wireless sensor and control industry, which really does cover an enormous range. If you sit and think for a moment and ask; what is the wireless sensor and control industry? What products belong to this family? Where are they placed and what do they do? Most consumers are aware of the “traditional” wireless products, such as mobile telephones or wireless broadband routers or car key fobs, but they are completely unaware of the less obvious devices out there? Well, they could be anything or anywhere, for example; A thermostat in a house or a commercial workplace, a drug delivery and are so anonymous in their existence in mesh network which assists in the monitor in a hospital or even in a leak that the user is completely unaware of the construction of larger (geography) networks. detector/alarm in a heavy industrial site engineering effort which has been There are also proprietary technologies such as an oil platform.

  11. 11. 11 wireless sensors and controls – special feature section Bluetooth: The second wave By: Mike Foley, Mike Foley, Bluetooth Special Bluetooth SIG Executive Director Interest Group Each year, the Bluetooth SIG membership and staff come together to examine where we’ve been in the past year and take those lessons learned to move our charter, the creation and promotion of Bluetooth, the best wireless technology, forward. This year marked our tenth All Hands Meeting (AHM), and my what a difference a decade makes. At our first gathering of minds in Los Angeles in 2002, Bluetooth chipsets were selling at $13 a pop (they sell for less than $1 today), analysts were predicting “millions of chipsets” to sell by 2005 (we sold almost 2B in 2010 alone), and just over 2000 companies had signed up for membership in the SIG – that number stands at more than 14,000 strong at latest count. The first wave of Bluetooth technology was a success by any measure. The technology experienced explosive growth, moving time to build on that success. The first of five Bluetooth Ecosystem Teams, known from 0 to almost 2B units shipped in less wave helped transform the mobile phone as BETs.

  13. 13. 13 wireless sensors and controls – special feature section EnOcean Alliance: buildings controlled over the Internet The Internet protocol (IP) has become a worldwide standard, with not only PCs or laptops but many other different devices communicating over the Internet. Currently there is much discussion of the idea of assigning every socket and every lamp its own IP address and then connecting them over the Internet. What many do not know is that today already all electric appliances can be addressed over an IP network — enabled by batteryless wireless technology and matching access points. EnOceans wireless solutions harvest the power they need from their surroundings — from motion, light or temperature differences — and in this way enable entirely energy-autonomous and maintenance-free automation applications. Teamed with the TCP/IP protocol the user has possibilities comparable to those of established building automation systems plus cost- savings in installation, huge simplification of the cabling, and flexible configuration of space. For this reason the operators of a retirement home in Germany decided to install the batteryless wireless solution. In a first step, the wireless system is being installed in the new building of the retirement community. Then the existing, adjoining building is to be converted.
