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?

To Mesh and Beyond

Not too long ago Bluetooth® SIG announced that Bluetooth® is going mesh, giving a rise to a new wave of interest to Mesh networking. Although the interest is growing rapidly, solutions available on the market keep using just the trusted star topology. But what are the real possibilities?

Mesh, Ad hoc and MANET

Most networks on the market are declared to be “mesh ad hoc,” so in most cases these terms are used together in turn blurring the difference between them. But there is a difference and it’s important to highlight it.

Mesh network is a kind of a network topology where all the possible connections between nodes are established. This leads to the main mesh network feature – self-healing, where broken routes can be restored using different access links between devices.

Ad hoc network is a decentralized wireless network that does not require any infrastructure to form and maintain. Nodes connection depends on its possibility. This network is self-configuring, which means that devices can join or form it on the fly.

In this way, mesh network is the most robust static type of ad hoc networks. But when both terms are used together, they typically mean ad hoc only. Mesh explains just the physical layer of wireless communication that is broadcasting from its nature where all devices that are close enough hear each other (i.e., connected) and form enough links for self-healing. To be completely accurate, it should be mentioned, that “ad hoc” means that the nodes are stationary. There is a term for mobile nodes – Mobile ad hoc networks (MANET’s). But today in PAN/LAN context (Wi-Fi, Bluetooth, ZigBee) nodes are assumed to be static due to their use cases, even if they can be moved sometimes from place to place.

Wi-Fi

Wi-Fi is an area that already has ad hoc solutions available through documents and open source. Official specification IEEE 802.11S is the less effective and innovative one. It introduces two new kinds of devices: Mesh portals and Mesh points. Mesh portals are ordinary Access points with wired connection to the Internet. Mesh points act as wireless routers between stations and portals. Everything that has “mesh” prefix is connected together where it is possible. The standard is completely the same as B.A.T.M.A.N. adv Wi-Fi mesh that is already included in the Linux core.

In parallel, open source community works on cjdns (Hyperboria) that is a real candidate for the DarkNet set of protocols. Cjdns is developed in the way to create a wireless mesh network that is totally disconnected from the Internet. Its core advantages are:

  • End-to-end encryption
  • Tunnels between segments over the Internet
  • Decentralized generation of IP addresses

The last one is a headache for all Wi-Fi ad hoc networks. Old DHCP conflicts with the essence of the ad hoc network and mobility.

Mesh networking using Wi-Fi sounds ready but not for small low-power devices. Thus, we better pay attention to Bluetooth® Low Energy (BLE) and ZigBee®.

Bluetooth®

The first thing that Mesh-network-sceptics say about Bluetooth® is that it was not designed for Mesh networking. However it is widely spread, so why not to try using it?

Existing solutions on BLE are nothing more than trying to sell things that we already have in ZigBee® under the “Mesh network” label. To build a “mesh” the customer should buy a BLE gateway that forwards packets to the cloud. All main-powered BLE devices act as routers and interconnected with each other, while battery powered devices talk to routers only. Nothing special.

But BLE wins in that it is already in devices that have the Internet connection through 3G, LTE, Wi-Fi, and even the cable. That means that in theory the customer can get more than one gateway connected by the Internet. Moreover, customer’s tablets and smartphones bring the mobility to such network.

The power of the Wi-Fi + BLE collaboration has already been explored by Apple: check out the Multipeer connectivity framework for iOS 7 and, for example, FireChat application that proudly announces “Internet is not needed to chat.”

ZigBee®

When talking about ZigBee® one thing should be kept in mind – it was initially designed to be ad hoc. The routing mechanism implemented in ZigBee® is called Ad hoc On-Demand Distance Vector (AODV). Although RFC is operating IP frames, there are no major differences. The algorithm is quite simple for CPU and gentle to ROM and is available even for a bulb or smart socket or any other main-powered device.

As it was mentioned earlier, ZigBee®-based systems on the market currently prefer to use star topology, even though it has everything to be a mesh network and should be used as such. When Wi-Fi or BLE implement mesh, it is not only a technological step forward, but a marketing reason. The truth is ZigBee® is already a step ahead in terms of technology, but maybe a step behind in terms of marketing.

One might mot like that ZigBee® network is not using IPv6. Well, neither does BLE, but it does not disturb it. Nevertheless, there is IEEE 802.15.4 + IPv6 + UDP solution called 6Lowpan and Thread or JupiterMesh built over it. Though they haven’t still made a splash on the market, probably nobody has positioned them as “mesh.”

As we can see, if the market wants mesh/ad hoc/MANET, there are all the pre-requisites for it. It is already around but the customer is not aware of it because either the market is too “shy” or that field has not yet been covered in depth. Anyway, the results will come soon and they will come from Wi-Fi, BLE, ZigBee or even a collaboration between them.
