Thoughts After CES 2019

CES 2019 at a Glance

Every year we make our way to CES (Consumer Electronics Show) in Las Vegas for the annual consumer electronics exhibition. Imagine over 4,500 vendors presenting new ideas and technological developments spread across an entire week — it really does give a whole new meaning to the city of lights. CES presents a great opportunity to meet like-minded individuals in similar fields, or different, helping catch new ideas, contacts, and ideas – it’s wonderful here.

The history of CES began over 52 years ago with organizers showing more progress each and every year. With the main theme being innovation and information technology, the width of coverage is vast:

  • Robotics,
  • Artificial Intelligence,
  • Three-dimensional Printing,
  • Design,
  • Drones,
  • Sport Technologies,
  • Smart Home,
  • Family & Lifestyle,
  • Virtual Reality (VR),
  • Games,
  • Unmanned Vehicles,
  • Music,
  • Entertainment & Content,
  • Cryptocurrency,
  • Internet of Things (IoT),
  • and Machine Intelligence.

 

All About IoT

The beginning of the year confirmed that IoT is coming to the mass market.  Focus has shifted from smartphones to other smart devices — and manufactures are taking notice.  Improved air quality sensors, door positions, windows, just to provide a few quick examples.  There are even smart window systems being developed that can inform the home when a window is opened wider than an indicated gap, for example.

Consumers can now choose between a wide variety of smart devices and systems, putting real pressure on manufactures and companies to advance smart home ecosystems. But the problem doesn’t just end there. Consumers need a way to connect many different smart devices to a single system – easy management.  This is where Zigbee and other wireless technologies flex their strength; gateways with multiantenna and customization service suggestions come to the rescue.

Hi Computer, Talk to Me

Voice automation control becomes more the norm than the rarity.  It falls into many devices and almost everyone has them now. People want to have a voice assistant in their home, in the office, and in the car, like Jarvis from Iron Man. Project recipes from the Internet to the kitchen door by voice request?  Yes, please!  Yet, even Alexa from Amazon or Google-assistant do not always suit as a compromising option.  Artificial intelligence is poised to grow wiser and communicate with people better and faster.  Companies that once winced at the idea of software in their products are now flocking to CES.  For example, Procter and Gamble – L’Oreal, are developing mirrors that can look at your face to determine if your skin needs support or treatment.  Maybe just a care cream?  Cameras take pictures of the users face and follow changes of the face in real time.  Maybe they’ll even notice skin cancer in due time.

It is interesting that companies that are seemingly far from “software” come into the sphere of technology.  These companies expand the development zone to such wide branches like automation for pets, children, sleep, and beauty.  There are even smart leashes and collars!  People even get interested in buying devices that can distribute pleasant smells throughout their homes.  And what if you could connect a device that could command three-dimensional TV? Cars? Batteries? Spotify on your steering wheel?  The ideas and possibilities are endless.

Robotics help businesses change their models.  It is especially gratifying that companies competing in the past are starting to cooperate.  To denote such activity, the new term ‘coopetition’ has appeared.  ‘Coopetition’ should bring even greater breakthroughs in overall development.  Teamwork gives rise to new achievements.  SDKs help bring the product to market.  Quick starts are real.

Meet & Talk

DSR had a lot of productive meetings with existing and prospective clients and it was the most successful CES to date. DSR was also a proud  sponsor of the Zigbee Alliance Social – an invitation only event that was a great opportunity to bring all of the members together in one location and celebrate Zigbee successes from 2018. During this event, Zigbee Alliance announced several of the new developments and expansions of the standard and also unveil the location of the next member meeting. The atmosphere for the event was very warm and inviting and perfect for conversations and celebration.

In Closing

Here are seven key CES 2019 takeaways that caught our attention:

  • IoT is finally an emerging mass market (and the data it gathers has lots of financial implications)
  • Amazon and Google are in “hand-to-hand combat” driving voice technology into the Smart Home and beyond
  • 5G, NB-IOT and Cat-M1 are expanding battery-powered WAN connectivity in amazing ways
  • Drones—from airborne to underwater to John Deere—are becoming platforms
  • Robotics are creating business change
  • Artificial Intelligence is getting smarter
  • “Coopetition” is happening in lots of places

IoT is moving capabilities out of smart phones and into different smart things. People want their homes, cars and offices to have a voice like Jarvis (see the Ironman movie franchise). And not everyone wants Amazon Alexa or Google Assistant as the go-between. Battery-powered WAN connectivity in a variety of speeds is making the cloud easier by “losing the gateway.” Drones and robotics platforms are giving new capabilities to businesses and consumers. Artificial Intelligence (“AI”) is changing the way products and services interact with humans. And if Apple and Samsung are teaming up, is it time to evaluate how “coopetition” might help your 2019 business goals?

What is Dotdot?

What is Dotdot?

A bit of history — the creation of Zigbee standard required a lot of effort, time and knowledge to construct. Dotdot is an alias for ZCLIP, which stands for Zigbee Cluster Library (ZCL) over IP. It is about exposing ZCL functionality to the IP world, in contrast to classic Zigbee that is always isolated from IP networks and requires a Zigbee gateway to connect Zigbee mesh with the outer world. This would become a bridge between IoT and other networks. Different manufacturers have Zigbee Gateway solutions mostly for connectivity of Zigbee network with cloud.

In classic Zigbee there are all instruments for organization, self-organization, restoring and stability of the network. Above all of this sits the Cluster Library, which calls functions allowing the clusters to communicate. Although, there is one short fall with this system – it cannot get online. With ZCL exposed to IP, it becomes possible to establish a direct communication channel between Internet/Intranet application and Dotdot device when border device remains transparent for and unaffected by the details of communication. The same way communication between Dotdot devices located on different networks is also possible under condition that device services are properly advertised across network borders or devices appear bound by means of a third-party application.

New Language: Old Terms, New Sense

Dotdot is a standard that allows you to put ZCL on any “rails” other than Zigbee – WiFi, Thread, and so on.  This is an add-on for Zigbee.  An application level protocol that allows smart devices from closed networks (with addresses) to communicate more openly through the address space that is on the Internet and other networks.  It is important to not just reach the device itself, but also to address the command to a specific cluster within, and do so securely.

 

Figuratively, Dotdot receives commands in one language and translates them into a language understandable for smart devices.  This makes smart devices ecosystem more open.  Dotdot uses the Zigbee approach in ZCL and has extended it to other types of transports as well. The mesh built for some Dotdot solution deployments is not mandated to contain only Dotdot-compatible devices.

The Commissioning Application

The Dotdot commissioning application was developed next to and based on Thread that was taken from the official Thread Commissioning App mostly as is, courtesy of the Thread Group. The application allows managing the expansion process of the Dotdot network. Seamless integration of the parts and stabilization of Thread for both mobile platforms was also performed.

This application allows third-party devices to enter, which is critical for maintaining network security.  The top layer works with Dotdot enabled devices over Thread. Thread is responsible for commissioning new Thread enabled devices to the home network and discovering devices that are already there. Dotdot makes use of device lists from Thread and as a result uncovers Dotdot enabled devices and their services. The system interrogates the device, finds what services and clusters are running, on which endpoint, and which commands support the device, allowing for a complete picture of the device’s capabilities.  Once this is completed, you are able to change the attributes and send commands from the application itself.  There are clusters, attributes, bindings and reporting.

Why Should Companies Implement Dotdot?

Speed. Abstraction. Interoperability. Dotdot provides the opportunity to create applications in a more flexible way. This is because Dotdot solutions use “generic” border routers that are standard, easy replaceable even at run time, and are not a “single point of failure.” The same data model is provided for different IoT technologies, despite what protocols are used to send data (WiFi, BLE, Zigbee, Thread, and so on), this means there is a wider market for solution spread. You can create a wider IoT system where all the devices understand each other. This creates an easier entry point for companies to develop solutions and allows application developers to focus on the application and functionality, without delving into the underlying specifics of a particular wireless network.

How to Get Started

  1. Download an SDK from a company that provides the solution.
  2. Study the provided API and Zigbee clusters description. Find the needed clusters and start own device (certified by Zigbee Alliance) implementation.
  3. Gain access to the Dotdot Commissioning Application.
  4. To accelerate your development, engage a company with experience in Dotdot and wireless technologies.
  5. Lastly, consider becoming a member of the Zigbee Alliance (if you are not already) to get access to even more tools and become involved in the development of IoT standards.
