Google Enters IoT World, Again

— June 18, 2015

The Internet of Things (IoT)—a much-hyped, though somewhat ambiguous, concept about interconnecting devices to create a system of systems for user convenience and detailed in Navigant Research’s IoT (Internet of Things) for Residential Customers report—is not a new concept.

For years, IoT products have been available to consumers, including smart thermostats, smart meters, connected LED bulbs, and more. Today, the IoT is being implemented by big names like AT&T, ADT, and Apple. Finally, one of the largest and most well-known multinational technology companies in the world is joining the race—Google.

In late May, Google unveiled its new IoT platform, Brillo, at the company’s annual developer event, Google I/O. Brillo is an operating system that manages connected devices, streamlined specifically for use in objects other than smartphones and tablets, which allows the user to create a true IoT smart home.

Brillo is based on Google’s existing Android operating system, which is important for integration with already existing Google technologies, like Google Now voice recognition. Brillo will be paired with Google’s newly created IoT language called Weave. Weave is a communications layer, enabling devices to talk with each other, the cloud, and Android-based smartphones. Google will make Brillo available to developers in 3Q 2015.

The Second Attempt

Brillo is not Google’s first attempt at entering the IoT world. In 2011, Google introduced Android@Home, a service designed to turn the user’s home into a network of Android accessories, using Android as the home’s operating system. Similar to Brillo, Android@Home was announced at a Google annual developer event four years ago. However, the Android@Home concept disappeared almost as quickly as it was introduced. Today, the digital landscape is much different, and consumers and developers more readily accept the concept of a connected lifestyle.

With a vast expanse of competition for creating interoperability in devices, it is unclear how Google’s Brillo and Weave will fair. Google has the kind of brand-name recognition that could turn this small, new concept into something very big—the kind of big that exists in nearly every home in America. The fact that Google is leveraging its Android platform also means immediate scalability, so many device manufacturers can use Brillo.

Challenges Ahead

However, there are already standard, protocol, and communication layers out there, and it is unclear how Brillo will react with these. Take, for example, ZigBee. ZigBee is a communications standard operating on IEEE 802.15.4 that has been around for over a decade. ZigBee already exists in millions of connected products, such as sensors and lights, and the next version (ZigBee 3.0, set to be released in 4Q 2015) is designed to unify and make an entire system of connected devices easier to use. This means that consumers may end up with Brillo/Weave devices and ZigBee devices that cannot communicate—a problem that will likely take some time to resolve. Regardless, Google and its entry into the IoT World is something to keep an eye on for years to come.


The Information Reality behind the Intelligent Building

— June 9, 2015

Big data and the Internet of Things (IoT) are the buzz when it comes to intelligent buildings. A slew of vendors are tagging their solutions and coming to market with a message of cost-effective intelligence that will redefine how we live and work in buildings.  But are we ready?

In mid-May, I attended Haystack Connect, an event that brought together a vibrant vendor community tackling the reality of the development of the intelligent building.  The panels and conversations circled on a vision for open-source data modelling via Project Haystack. According to Project Haystack’s website, the project is an open source initiative to streamline working with data from the IoT and to standardize semantic data models and web services with the goal of making it easier to unlock value from the vast quantity of data being generated by the smart devices that permeate our homes, buildings, factories, and cities. The applications the project focuses on include automation, control, energy, HVAC, lighting, and other environmental systems.

Two lessons learned: First off, big data is a marketing tagline, but building owners want to know what it does for them. Second, the IoT can generate a whole lot of information, but the key is accuracy and action.

Big Data – More Isn’t Necessarily Better

The demand for intelligence is ubiquitous, from smart phones to smart watches, and the notion of data-driven decision-making is helping to accelerate customer demand for smart buildings. Getting the data from large existing buildings and making sense of what it means across an enterprise is no small feat. As one speaker put it, “This problem is not the domain of the data scientist.”  In other words, there is building technology and engineering expertise that has to be a part of the equation. In the Project Haystack world, this is about cleaning and processing system information with consistent approaches via tags that speak the same language. Without common naming, analytics can hit a wall.

The Promise of Data Granularity

The trajectory for device connectivity is impressive, and underlying the evolution in technology adoption is the maturation of cost-effective tools that make actionable building intelligence accessible to an ever-growing audience.  Wireless sensors and controllers can not only add granularity to the assessment of building performance, but also open the door to smaller facilities that have been out of reach for the legacy building controls industry.  The exposure of new applications to a wider audience is a critical step in the process of market maturation for smart buildings. As these solutions become adopted across customer segments, market awareness and business value will only increase.


Slower Networks May Be the Answer for Cities, Utilities, and Buildings

— May 29, 2015

A communications technology that promises lower bandwidth and higher latency seems an unlikely proposition in an age when the demands for speed and capacity are rising inexorably. However, low-power wide area networks (LPWANs) are set to play an important role in expanding the possibilities for the Internet of Things (IoT) in cities, buildings, and utility networks. LPWANs are targeted at applications that have low or infrequent data throughputs but which benefit from low-cost modems (less than $5), cheap connectivity (a service cost of a few dollars per year), long-range access, deep penetration, and an extended battery life for devices (around 10 years on a standard battery).

LPWANs come in a number of flavors. In February of this year, the LoRa Alliance was launched by a group of technology suppliers and telecoms operators that support the LoRaWAN specification by developed semiconductor company, Semtech. Initial supporters of the Alliance include Cisco, IBM, Sagemcom, and Semtech, alongside telecoms such as Bouygues Telecom, KPN, SingTel, and Swisscom. One of the first project announcements is partnership between French IoT supplier Actility and Swisscom to deploy a LPWAN around the cities of Geneva and Zurich.

Other players in the LPWAN space are focusing on the evolution of 4G LTE standards that will enable low-cost, low-power communications to support machine-to-machine applications. Several telecoms and equipment providers have announced what is referred to as LTE-M projects, including Nokia and Korea Telcom. Vodafone has also announced its own low-power IoT service, dubbed the Cellular Internet of Things, which it has developed in partnership with Huawei.

Another significant LWPAN initiative comes from French communications company SIGFOX, which is working globally with network system operators to deploy LWPANs using its ultra-narrowband technology. In the United Kingdom, for example, Arqiva is rolling out a SIGFOX-compatible network to 10 cities initially.

Do the Pros Outweigh the Cons?

LWPANs offer the prospect of sensors and other intelligent devices being able to connect instantly into a communications network at a cost of a few dollars a year. LPWANs are suitable for applications where high bandwidth and low latency are less important. LPWANs are not suited, for example, to applications requiring high bandwidth (such as video streaming), low latency, or the continuous tracking of moving objects. LPWANs are largely complementary to existing network technologies, but may present competition to radio frequency (RF) mesh technologies for applications such as smart street lighting and smart parking, and even some forms of smart metering.

LPWANs allow for low-cost piloting and easy scaling of innovative applications. A supplier developing a smart city solution, for example, could quickly demonstrate the benefits of an application for air quality monitoring. Similarly, a utility could use a sensor connected to a LPWAN to monitor assets that lack local power (such as gas and water pipelines) or where the business case does not justify a more expensive solution. A facility manager could use LPWANs to fill gaps in their existing building management system or to retrofit sensors to older buildings.

The LPWAN market is in the innovation phase, where an explosion of different approaches is to be expected and indeed welcomed. However, multiple versions and standards are likely to confuse potential adopters, and industry players need to push ahead on the development of open standards and interoperability models. Over the longer term we will see a growing focus on the so-called HetNet environments in cities, which will allow seamless integration across network protocols depending on location and requirement. In the meantime, low-power networks can be an important accelerator for smart cities and other IoT markets.


How the Internet of Things is Changing Healthcare

— February 25, 2015

Much talked about in the energy efficiency sector, the Internet of Things (IoT) refers to a world where everything from lamps to HVAC systems to entire grids will one day be connected. The concept has gained traction in recent years, but deployments remain modest. Only an estimated 1% of the world’s buildings use systems to control and network lighting, and only 7% of commercial building lighting is operated using smart controls.

However, controls products offer huge energy consumption savings opportunities. Enlighted Inc., one lighting controls vendor, claims that its wireless sensor system can cut commercial building energy consumption by 50% to 75%. In an environment where healthcare costs are predicted to increase by 6% annually for the next decade and uncertainty lingers concerning the Affordable Care Act, cost-savings opportunities like that are enthusiastically welcomed.

Update Needed

In the healthcare sector, IT investments increasingly emphasize connectivity and networked systems. Networking enables healthcare systems to lower costs while improving patient experiences and facilitating an advanced degree of care customization. Particularly in the United States, where the cost of patient discharge is about $18,000 (versus $6,000 in other developed nations), networked systems can dramatically cut administrative costs.

One of the greatest benefits is the ability to test and diagnose devices remotely. This can help to reduce device downtime and avoid unexpected breakdowns, thus avoiding shutdown costs and patient rescheduling. Connected devices, such as MRIs, CT scanners, and lab test equipment, can signal when critical operational components are being depleted.

Efficient scheduling is another benefit of IoT technology in healthcare facilities. By leveraging utilization statistics, hospital employees are able to optimize equipment use and avoid over-scheduling procedures.

Seeing the Patterns

The expanded capabilities of smart, connected products and the data they generate are becoming necessary in the increasingly competitive healthcare sector. In addition to cost-cutting benefits, the IoT is opening extensive opportunities for improved operational efficiency and patient satisfaction. This emerging Internet of Healthy Things is composed of apps and hardware that promote positive health outcomes and focus on preventive healthcare for individuals. For example, Fitbit’s wearable device captures health-related data, such as sleep patterns, activity levels, and other personal metrics, to provide a complete picture of behavior and baseline vital signs. Medical device companies offer home health-monitoring systems that allow physicians to remotely monitor their patients’ clinical status. For example, Propeller Health’s asthma and chronic obstructive pulmonary disease (COPD) tracker allows a doctor to remotely monitor patients’ symptoms. Other apps exist to monitor a range of other health issues, including diabetes.

Although the healthcare sector has been traditionally slow to embrace new technology, the IoT offers improvements for both facility management and individual patient care. As tele-health and other in-home care options continue to expand, IoT-enabled devices can enable progressive hospitals to remain competitive—and improve outcomes.
