      • Bringing SmartThings to Life at the Samsung Developers Conference

        lethawicker | 11/328/2014 | 10:28 AM

        It’s not hard to understand the appeal of a smart house full of IoT-connected devices, but seeing it in action really drives home (if you’ll pardon the pun) the benefits. At the Samsung Developer’s Conference, Silicon Labs’ customer SmartThings showed off a model home full of interconnected goodness, including some crucial IoT infrastructure devices you may not have even considered.


        First of all, let’s set the stage. Here’s what the entire Connected Home looked like at the conference:





        There’s a lot of cool technology on display here, but if you look closer, you can see the hidden gems that will really make the IoT an indispensable part of our lives. Like this little guy:




        It’s a Smart Vent from Keen Home, and it has Silicon Labs’ ZigBee wireless SoCs connecting it to the mesh network. This device allows you to set up comfort zones for various areas of your house, so everyone is toasty (or cool) just the way they prefer.


        And you probably missed this little motion sensor, too, which is the point:




        Ever worry that you’ve left water running, or come home to discover a leak that’s been wasting water and driving up your bill all day? This smart water sensor would let you know so you could fix the problem before it actually becomes a problem.




        The final and (we think) most compelling stop on the SmartThings home tour was a work station where visitors could see for themselves how easy it is to design their own ‘smart thing’ for the IoT using Silicon Labs’ innovative, simple, low-power solutions.

        Today, we make a good thing even better. Silicon Labs’ new EZRadio and EZRadioPRO families offer the highest levels of RF performance and single-chip integration in the sub-GHz wireless IC market. These sub-GHz wireless ICs provide support for 802.15.4 and WMBus and have long-range capabilities.



        Ideally suited for battery-powered wireless applications, the EZRadio and EZRadioPRO devices provide the industry’s lowest standby current with memory retention, consuming up to 75 percent less sleep mode current than competing solutions. Each device includes a patent-pending signal arrival detector that reduces the average receiver current by detecting a signal faster than traditional sub-GHz receivers, effectively increasing the battery life for various applications.


        These energy-friendly sub-GHz radios can operate on a single coin cell battery, and they are well suited for smart meter designs that require long-range and up to 20-year battery lifetime. Autonomous duty cycling between active and low-power modes and advanced features such as frequency hopping and antenna diversity minimize host MCU interaction and further reduce overall system power consumption.


        Silicon Labs’ sub-GHz radios support a wide variety of proprietary protocols through flexible on-chip packet handler and modem technology. EZRadio devices handle most basic packet formats, while EZRadioPRO devices are designed for more complex packet formats. The flexible architecture offloads the host microcontroller (MCU) without sacrificing RF performance. EZRadio and EZRadioPRO devices can support a protocol stack such as an 802.15.4-based mesh network or a point-to-point or star network in conjunction with a Silicon Labs 8-bit MCU or a 32-bit EFM32® Gecko MCU as the external host.


        Si4x55 EZRadio transceivers, transmitters and receivers provide cost-effective, easy-to-use wireless connectivity solutions for basic “push-button” applications such as remote controls for set-top boxes, bidirectional key fobs and garage door openers.


        Si4x6x EZRadioPRO transceivers, transmitters and receivers are an excellent choice for developers requiring advanced features, higher RF performance and a wider range of protocol options. They are ideal for ultra-long-range, narrow-band applications using complex, advanced packet formats and network protocols.

        From the Thread Group launch on July 15 to the Thread Information Session at the Googleplex on September 30, the buzz and excitement around the new Thread protocol continues to build. The Thread initiative has generated tons of positive press coverage, and questions about thread from interested developers come to us daily. More than 100 articles appeared online within a day of the Thread announcement, and more 400 engineers showed up at the recent information session to learn more about Thread.




        So what’s all the buzz around Thread, and how is Silicon Labs involved in the initiative?


        Many IoT developers are actively inventing new connected devices and services, and they are eager for new connectivity options that will make it easier to deploy their solutions in the Connected Home. All of these devices and services will become simpler if they are based on an IP stack and provide IP connectivity. Low-power 802.15.4 radios have been pervasive in connected device applications, and tens of millions of these radios ship every year into the Connected Home. Clearly, the IoT market welcomes a new IP-based mesh networking solution, and countless engineers are excited about adding IP connectivity to their connected devices.


        Thread is an IP-based networking stack specifically built for the constraints of the Connected Home, offering ultra-low power, high security and ease of use. Thread provides a reliable and robust mesh network with direct IP addressability for all the wireless sensor nodes and connected devices in your home. Best of all, Thread runs on many of today’s existing wireless SoCs, such as Silicon Labs’ Ember®ZigBee® SoCs, and can be deployed on 802.15.4 radios with simple over-the-air software updates.


        Silicon Labs is one of the founding members of the Thread Group, and we are a member of the Thread Board along with Nest, Samsung, ARM, Freescale, Yale Locks and Big Ass Fans. We are deeply involved in the Thread organization and are helping to drive the development of the underlying technology. Our mesh networking team in Boston has been working on IP-based mesh networking technology for more than two years, and it’s exciting to showcase the emerging Thread protocol to developers everywhere.




        Skip Ashton discusses the Connected Home and IP-based mesh networking requirements at the Thread Information Session on Sept. 30


        In talking to developers at the Thread Information Session, I discovered that many of them have been struggling to get a robust and reliable IP stack running on their own. A number of developers shared stories of their adventures in trying to get a Contiki stack to some level of performance. They were very excited that a group like Thread has been working on this challenge and can now provide a functional IP stack for 802.15.4 wireless devices.

        Thread is designed to unify the existing set of protocols running in the Connected Home. Using IP connectivity, we can expect simpler development and easier communication across multiple physical layers such as 802.15.4, Wi-Fi and Bluetooth. With Thread, developers will be able to invent new connected devices and services and see them deployed in our homes – and with the confidence that they will be interconnected through a robust, secure Thread mesh network.


        Membership in the Thread Group opened on October 1, and through the end of this year and beyond into 2015, we are all looking forward to seeing the rapid roll out of this exciting new IP-based mesh networking technology. Silicon Labs will continue to innovate around wireless connectivity, and our customers can expect to have early access to these new software stacks for their development.
