Redpine Signals is Now Part of Silicon Labs

Our recent acquisition of Redpine Signals added a valuable amount of technology and capability into our existing vault of expertise. The acquisition highlights the RS9116 family of chips, which comes from a line of three generations of wireless products from the previous RS9110 (Gen 1) and RS9113 (Gen 2).

Redpine Signals’ brings broad expertise in Wi-Fi and Bluetooth solutions with these products using the key technologies of ultra-low system power, multi-protocol (802.11, BT/BLE 5), and multi-threaded processors. These high-performance solutions come with an embedded wireless and networking software, along with multiple security levels, edge intelligence, and ultra-small form factor. All of these features are ideal for multiple target markets such as smart homes, fitness/wearables, healthcare, and industrial.

Expanding the Silicon Labs Wi-Fi Product Family

Our current portfolio of Wi-Fi solutions consists of two categories: Transceiver SoCs & Modules and Full-Network Co-processor SoCs & Modules. The former comprises our WF200/WFM200S and RS9116 n-Link, while the latter is our RS9116 WiseConnect.

The WF200/WFM200S module operates on 2.4 GHz Wi-Fi along with higher-level network and security stacks running on the host processor, either MCU or MPU. The RS9116 n-Link operates on 2.4/5 GHz Wi-Fi, as well as BT and BLE 5. This module also runs wireless, network, and security stacks on the host processor (MCU or MPU). The RS9116 WiseConnect runs wireless, network, and security stacks on the RS9116 while the application runs on the host processor (MCU).

IoT Application Examples of the RS9116

What can the RS9116 do to enable your IoT product development? As mentioned, the RS9116 has all the features that could serve multiple markets.

In the world of smart homes, RS9116 uses Wi-Fi communication for local and cloud control of different devices like locks, cameras, thermostats, and others. During installation, BLE communication is used to provision smart home devices to a home’s or site’s Wi-Fi network. This requirement is made possible through the built-in coexistence manager to manage Wi-Fi and Bluetooth LE coexistence. The RS9116 also features low current consumption in ultra-low power mode for battery-operated smart home devices, which is ideal for power efficiency and long battery life.

Another area of application for the RS9116 is wearable devices. This application also features ultra-low power consumption for extended battery life. Still, it is slightly different than a typical smart home device because of the simultaneous multi-protocol communication requirements as follows:

• Heavy communications in 2.4 GHz ISM
• Wi-Fi connected to the cloud through AP with downloads, streaming, notifications, updates, etc.
• BT EDR wireless A2DP music streaming
• BLE peripheral connections to smartphones and tablets and central connections to sensors

The smart home is the new rising standard for a “home sweet home.” With increasing connectivity of home appliances and devices, IoT technology has enabled the smart home ecosystem to expand based on consumer demand for interoperability. At CES 2020, Matt Johnson, our SVP & GM IoT Products, spoke in an interview with EETimes about the exciting future of the smart home and shared his predictions on industry growth over the next decade.

As Matt stated in the interview, one of the major challenges to the growth of the smart home market is interoperability. Developers are expected to move quickly across competing industry standards, while consumers demand smart home devices that work seamlessly with the ones they currently use.

Project Connected Home over IP and Z-Wave Alliance have recently announced plans to make smart home technology more compatible, enabling technology access for developers, better consumer experience and faster industry growth. We also recently launched EFRBG22, a secure Bluetooth 5.2 SoC delivering industry-leading energy efficiency that can extend battery life beyond five years, allowing for highly accurate motion tracking that can be used in a variety of home applications. These technologies help fulfill the needs of consumers and enable connected intelligence to function in a faster, safer and more cost-effective way.  

As IoT expands the smart home market, consumer dreams of a smart, connected home are becoming a reality. Despite challenges in a fragmented market, issues in interoperability, and slow adoption, Silicon Labs helped jumpstart the movement of homes embracing connectivity. We are excited to host the "Works With" Smart Home Conference in Austin, Sept 9-11, bringing smart home designers and developers interested in creating products that work with the world's largest smart home ecosystems.

The future of the IoT is open, seamless and secure.

We welcome the launch of the Connected Home over IP project and strongly support the working group dedicated to developing and promoting a new, open-source wireless protocol designed to increase compatibility among smart home products, with IP connectivity and IoT security being foundational design elements.

We are committed to advancing open wireless technologies and platforms for the IoT. We look forward to working with the Zigbee Alliance and fellow board members including IKEA, Legrand, NXP, Resideo, Samsung SmartThings, Schneider Electric, Signify (Philips Hue), Somfy and Wulian to drive the success of the Connected Home over IP project.

As a Zigbee Alliance board member, we will contribute to the project to create a new IP-based protocol enabling secure, reliable and seamless smart home connectivity. We encourage everyone in the smart home industry to get behind this much-needed project aimed to simplify development for IoT device manufacturers and increase ecosystem compatibility for consumers everywhere.

Earlier this year, we spoke with Ryan Kincaid, an Allegion global hardware architect, who focuses on connectivity and the security of embedded systems. Allegion is a long-standing and trusted brand in mechanical security, with a 100 + year history of building locks and entry systems for residential and commercial buildings. With more than 30 brands in 130 countries, Allegion has been specializing in security since long before electronics of any kind even existed.

True to its pioneering roots, Allegion sees tremendous opportunity in IoT to create even more value within its product portfolio. Over the past few years, the company has been working closely with Silicon Labs to add connectivity to a broad spectrum of smart home and commercial security products in its portfolio.

In the blog below, Ryan shares insight behind some of these new products and use cases for access control technology, including enabling features like granting delivery personnel access into homes without the need for the homeowner to be on-site.

Tell me a little bit about Allegion.

Many people are familiar with Allegion’s brands without even knowing it. For example, if you look at your key chain, there’s probably a key that says Schlage on it, which is one of our core U.S. brands. Schlage can also be found on exterior and interior locks in your house. When you walk through an entry way of a commercial building, people often push our Von Duprin exit devices to open the door (that’s the bar running across the door) or use a credential reader to gain access. Many people first think of these brands as mechanical, but what is happening in the industry is a migration of electrifying mechanical devices. We are adding in connectivity, sensor technologies, and fairly high-end embedded security to make them intelligent.

Can you tell me about how Allegion is working with Silicon Labs?

We use Silicon Labs in a variety of different products, especially related to connectivity and our connected home solutions. We started using Silicon Labs’ technology through the acquisition of BlueGiga and quickly saw the benefit of the support Silicon Labs provided. We have gone on to leverage products like the Silicon Labs Mighty Gecko SoC and others over time. For example, we recently worked with Silicon Labs to develop a Zigbee-certified smart home lock, a solution great for people who want in-home delivery. A homeowner can grant access to a third-party, such as Amazon, and allow that delivery service access on a limited basis to that person’s door (which can also be paired up with a camera). When the delivery person arrives at the home, he or she can unlock the home and lock on their way out.

Another product we launched recently is a networked version of an exit device that allows remote monitoring and access control in commercial settings. This product utilizes the Blue Gecko SoC and is targeted specifically at the K-12 educational vertical. We call it a safe school application, as it enhances perimeter security by providing electronic override of mechanical solutions for an emergency facility lockdown. This product can be invaluable to school administrators as prior to this type of technology, a human would have to go around to every single access point and ensure it was securely locked.

What are some of the major product design challenges you typically run into?

Time to market is always a challenge. We have found Silicon Labs’ offering of both SoC and pre-certified module (FCC certified modules) solutions especially valuable to us. The pre-certified modules accelerate our time to market because we can circumvent some of the compliance and certification processes. For example, the Zigbee product I mentioned earlier was not a new technology to the industry, but it was new for our product line, and being able to use the tools and certification support Silicon Labs provided really sped up our product delivery. One of our other largest challenges is decreasing our time to market while maintaining our high standards for safety and security.

How important is security and how do you see security evolving with IoT?

Security is priority number one – there is no question about that. For example, at schools, connected devices allow for fast and safe lockdowns. At home, you can get an alert when your child arrives home from school and enters the door, allow temporary access to a visitor, and verify that the door is locked before you turn out the lights.

Our reputation is built on security, so when it comes to adding electronics to mechanical solutions, our security mindset comes with us. We have added roles within the company that specifically focus on cybersecurity. When we look to products that we’re using within our embedded system, we’re constantly refreshing our security requirements around those pieces. This includes enabling security updates in the field. When we look for silicon or firmware partners, security is always the first thing we review.

One of the things we want consumers to be mindful of is the market is full of products touting home security, but some of these are companies don’t necessarily have the history or track record that we do.

Where do you see IoT going in the next 5-8 years?

I think consumers are becoming more and more aware of security. They might not know all of the encryption standards and data privacy laws, but they’re getting to the point where they are asking sophisticated security questions, and people developing IoT products need to meet these new demands. This will drive new security standards, data storage requirements and computing at the edge.

There will be an increase in consumers questioning a product’s digital longevity. How long will this be supported? Will I continue to receive updates? Will the pricing model change? To be successful in the IoT market for the long run, manufacturers must have scalability and sustainability product plans in place before delivering each and every IoT device to market.

Finally, we will see a demand for a better user experience in IoT. Devices need to be easily commissioned and seamlessly work within the intended ecosystem. This could include sharing data with a smart devices or cloud services. Products constantly need to be checked for compatibility due to the rapid change in these technologies. Products genuinely need to address customer needs without becoming an annoyance. 

We recently had the opportunity to sit down with the CTO and co-founder of Notion, Ryan Margoles to talk about the release of their Gen 3 sensors and how the IoT will impact homeowners in ways that go beyond just convenience. 

Tell us about the history of Notion. What was the impetus for starting the company and what were the immediate challenges?

The idea for Notion was literally sparked by a sounding alarm in the middle of the night. My wife and I had just adopted a puppy and our carbon monoxide alarm went off at 2am; it was a pretty jarring experience. We jumped out of bed and opened all the windows and exited the house. Fortunately, it was only the furnace fizzling out. The next day, I called my business partner and childhood friend, Brett, with the idea to make a Wi-Fi connected smoke/carbon monoxide alarm. We set out to learn more about the value proposition of a smart smoke alarm, and how we could make it valuable for customers. We learned quickly that people loved the use case, but were not used to buying smoke or CO2 alarms; they are usually already installed in the apartment or in the home you buy. The product evolved and coalesced into a concept of a single sensor that could do multiple things: listen for smoke/CO2 alarms, detect movement, doors and windows opening/closing, freezing temperature, and leak detection. The competition offered several single-function sensors: a door sensor, a temperature sensor or a leak sensor. In our opinion, this was a barrier to entry for people who aren’t as tech savvy. We knew we had found the right idea to pursue.

What is your background?

I have a mechanical engineering degree from the University of Colorado. My background is in product development, manufacturing and big data. I spent most of my early career with Titleist and Callaway developing smart golf clubs.

When you set out to do this, size and battery power were obvious considerations. What were some other known design challenges?

There were three challenges on the onset: 1.) Battery usage: Battery power and replacing batteries every three months is tough for a customer to get used to; it’s a hassle. Our Gen 1 kit had a coin-cell battery that was difficult to swap out. We learned over time that just two AAA alkaline batteries were important since they are readily available and easy to change out. 2.) Ingress protection: Devices that are placed outside, in really cold environments or used for water leaks need to limit the amount of water that gets into the devices. 3.) Simple user

experience: it was a challenge to design a simple user setup. One of the areas of opportunity was the pairing process. With most smart devices, you have to go through a pairing process. We identified that as a pain point for users so we developed our own protocol for pairing devices. Our goal is ease-of use. Every device is the same. It detects all five “senses” and device tasks are 100% configurable in the Notion smartphone app.

How did Silicon Labs become part of Notion?

First and foremost, the account management team at Silicon Labs is easy to work with. We were able to get the answers we needed to make important decisions and the team availed themselves to all-levels of the Notion organization, from executives to hardware engineers. Second, the Gecko platform allows us to configure specific protocols and free our team to focus on other things. Previously, the Notion team developed everything – from OTA update mechanisms to the security protocols. It was very labor intensive. Silicon Labs helped alleviate much of this burden. Third, the Silicon Labs team spent the time building rapport and working with us on a pricing model that worked for our start-up.

What’s been the market’s response to Notion?

Overwhelmingly positive. It’s the best multi-functional sensor on the market with its simple 15-minutes-or-less set up, increased range, and long battery life. Our channel strategy includes not only B2C, but also B2B; we are partnered with several of the top insurance companies in the U.S. Similar to car sensors that help lower your insurance premiums for good driving, we’ve pursued a similar path for home ownership. Now a homeowner or renter can augment their monthly premium by installing Notion. Additionally, we’re the first IoT company to have

a partnership with HomeAdvisor. So, if you have a water leak, we not only detect it, but we can connect you with an available plumber in your area within 30 seconds.

What do you see is the vision for the future of Notion, and the IoT in general?

We believe the services extension of IoT is changing what it means to have a smart home. Being a homeowner is hard and our mission is to help you take care of your home. We have a 10-year goal of making Notion a requirement to obtain property insurance -- that’s how powerful we think our product and data is. We partnered with one of our insurance partners, Hippo, to be the first fully-integrated smart insurance product on the market. Every customer who buys Hippo insurance receives a Notion starter kit for free. Once the customer sets up their

Notion system, they get an exclusive discount on their premium. We’re driving insurance to make a change while adding thoughtful services to the Notion brand to help homeowners take care of and secure their home.

There is a huge demand today for adding Wi-Fi connectivity to IoT applications because of the many advantages over other wireless protocols (Zigbee, Bluetooth, etc.) such as longer range, native IP connectivity, and high bandwidth. For millions of IoT applications, including industrial machines and sensors, Wi-Fi is often the best choice for connectivity because of its robust infrastructure and global reach- Wi-Fi exists almost everywhere in the world today.

Challenges for developers: The biggest challenge for developers has been the high-power consumption of Wi-Fi in IoT systems. Wi-Fi protocols were designed primarily to optimize bandwidth, range, and throughput, not power consumption. This makes it a poor choice for power-constrained applications that rely on battery power. Of the various cons of using standard Wi-Fi protocols, high power consumption is the most impactful (range limitations and busy networks are cons as well). Until today, developers have avoided adding Wi-Fi to their IoT applications as there hasn’t been a viable option for adding Wi-Fi connectivity to battery operated devices that didn’t require high power consumption.

These are the four key challenges when adding Wi-Fi connectivity:

• selecting the appropriate Wi-Fi protocol for energy efficiency
• costly compared to other protocols
• more time and resources needed compared to other wireless protocols
• form factor constraints

Power consumption in Wi-Fi varies dramatically across various modes of operation and it’s important to understand the different modes and optimize them to reduce overall power consumption. One strategy is to stay in the lowest power mode as much as possible and transmit/receive data quickly when needed.

RF performance: Unlike many wireless protocols, Wi-Fi power consumption is significantly impacted by RF performance and network conditions. This is a significant problem with the increasingly crowded Wi-Fi networks today. A busy network leads to many retries/retransmissions which consumes a high level of power. Developers must focus on reducing retransmissions and controlling link budgets to be successful.

Wi-Fi devices typically consume significant power in both Transmit (Tx) and Receive (Rx) modes. There are several ways to reduce power consumption and optimize Tx and Rx modes. First choose devices with high selectivity/out of band rejection. Also, choose devices with high Rx sensitivity, and if possible, choose uncrowded channels for device operation. This might mean using channels not used by chatty connections such as video streaming.

Applications: Power consumption is highly dependent on the application and use case. IoT applications typically fall into one of three categories:

Always on/connected-these devices are always on which allows users to access the device remotely at any time via cloud or mobile application.  A Wi-Fi video camera is a good example of this use case. Latency is a critical factor in these applications and power consumption is dominated by the transmit power mode (the highest power consumption), as the device is transmitting data and it would be detrimental to be inactive or inaccessible.

Periodically connected - These devices are connected to a remote server or cloud platform and only need to transmit occasionally. A good example is a temperature or humidity sensor that sends data every few minutes and it can tolerate the small amount of time it takes to become active. Latency is not a major concern and the power consumption is dominated by receive and sleep currents. It stays in intermediate power levels so it’s never completely awake or asleep so it wakes up faster.

Event-driven - An online shopping order button is a good example of event-driven Wi-Fi connectivity. It’s almost always inactive/asleep, meaning there is no data transmission. It wakes up infrequently, and it takes longer to wake up from this mode. An event occurs that triggers wakeup such as when a user selects the order button. This mode is dominated by the lowest sleep current and is best when needing to use the least amount of power possible for an IoT application.

Design issues -  Lowering Wi-Fi power consumption is also a design system issue and is a critical challenge for developers today. Power management and extended battery life are major factors when developing IoT applications. Although standard Wi-Fi protocols weren’t designed initially for low power operations, there are many techniques to help significantly reduce power consumption. These techniques include optimizing Rx and Tx modes, optimizing power-saving modes (sleep modes, WMM, DTIM, shutdown/standby), choosing the right hardware, using built-in specifications, optimizing RF performance, and system level optimization. Developers must understand all the contributing factors to overall energy consumption in IoT devices.

They must also understand both system-level factors and deep application factors in order to achieve low energy consumption in their applications. Finding the right mix of power-saving Wi-Fi modes and selecting the right hardware are the keys to dramatically reducing power consumption. Leveraging hardware and software designed specifically for IoT devices and low power consumption can reduce long term costs, overcome development challenges, extend battery life, and potentially enhance the life of products and customer satisfaction.

We solve the power management issues for IoT developers by providing drop-in Wi-Fi solutions, including pre-programmed modules (WF200 and WGM160) that can cut power consumption in half. These solutions are designed proactively with low power IoT applications in mind and work in a wide range of applications from home automation to commercial, retail, security, and consumer health-care products. Pre-programmed modules provide a prototype quickly which helps developers get products to market faster.

Silicon Labs has an unusually broad perspective of the smart home market, being we provide both chipset and wireless solutions to a vast array of global smart home customers. But what makes us especially unique is that we support most all of the major smart home connectivity protocols, and even offer solutions to help customers create their own wireless protocols. Wireless connectivity is complicated, but it’s getting remarkably easier for both designers and users as time goes by. And as it does, the smart home is getting much smarter.

The smart home market as we know it initially started in the early 2000s, and for many years, the question has always been – when is mass adoption going to happen? No one knows for sure. Yet we are confident adoption rates will increase substantially this coming year. According to Statista, there are already nearly 35 million smart homes in the U.S. in 2018, with growth expected toward 60 million homes by 2023. People have been using smart home thermostats, lighting, and security products for quite a few years now, but the smart speakers recently introduced have been an explosive driver for the smart home. More than 50 percent of smart speaker owners have gone on to buy other smart home products, and Gartner predicts that 75 percent of U.S. households will have smart speakers by 2020.

So what’s coming up in 2019 that will be different for the smart home? Silicon Labs shares some predictions below.

Professionals take a backseat: One of the shortcomings of the smart home thus far has been the tendency for people to buy the application they want, but once they get the package home, the installation is too complicated and an outside professional is required to install the device. Thanks to new highly interoperable smart home platforms, such as the Silicon Labs Z-Wave SmartStart, the installation of products is becoming surprisingly easier. Ring is a good example of a new plug and play security smart home product that just needs to be plugged in, then the user sees the application on their phone. It’s that easy.

AI and smart home unite: Wireless and mesh connectivity solutions have improved dramatically in range and power consumption in recent years, enabling low-costs sensors to be deployed across the home (and yard). No longer limited by short ranges and power constraints, ubiquitous devices are giving the smart home the ability to react intelligently to changing conditions. The smart home has already seen the first iterations of AI, otherwise known as context-aware intelligence, in consumer products, and more are on the way. A popular example is the smart thermostat that learns family preferences. New smart thermostats will sense how many people are in which rooms of the house and adjust accordingly. They will know what time of day energy prices drop and react for optimal economy.

Insurance industry adoption: More than ten years ago we saw smart home thermostat products disrupt the utility market, and we’re going to see those kinds of dynamics happen again in other markets. Smart home insurance IoT products are something to watch closely this year. Context-aware smart homes are allowing the insurance industry to move its central business paradigm from reactive claim services in to proactive loss prevention. A draft in the home can be traced to a roof in need of costly repair. Moisture in the garage can distinguish between a simple worn valve or an expensive leak in the foundation. Water Hero, an IoT product that detects a water leak in the house before it escalates, is the first of many new insurance IoT products that will continue to hit the market in the coming year.

Homes get even smarter: Some of the early smart home consumer products centered around video monitoring, yet a more sophisticated sensing is materializing. New smart home products for Aging in Place are a great example. Keeping close watch on older and more fragile family members doesn’t mean they need to be watched via obtrusive video cameras. Instead, data can be collected about elderly daily habits from invisible sensors in appliances, lights, rooms, medicine cabinets, etc. If the data shows unusual irregularities, family members can be notified.

Costs decrease, longevity increases: The beauty of a maturing technology market is as the technology advances, the costs come down, and this dynamic will be no different in 2019 for the smart home. Besides decreasing consumer costs, we’ll also see major gains in battery and low power. A truly smart environment features embedded sensing throughout the entire space, including areas where direct electrical power is either impossible or impractical. Battery operated devices are a necessary mainstay of the smart home landscape. Due to their need for continual battery replacement, service providers and end users often limit the deployment of these devices, thus limiting the life cycle of the system. The recently released Silicon Labs Z-Wave 700 platform is so efficient that it can allow battery operated devices to provide ten years of service on a single coin cell battery. We will start seeing the benefits of this battery development in the coming year as applications roll out based on the technology.

We'd love to hear about what you're expecting from the smart home market this year.
