The Zigbee Alliance and Thread Group has announced the availability of the Dotdot specification over the Thread IP network. Developers can use an established, open, and interoperable IoT language over a low-power wireless IP network, which will help unify the connected device industry and unlock new markets.
“We’re at a point in the Smart Home where the broader consumer market is embracing mainstream connected products; 26 percent of consumers own a smart home device according to research,” says Tom Kerber, director of IoT strategy at Parks Associates. “To be competitive in a market where consumers will rely on these devices for years to come, companies must take a long-term view, aligning with technologies that will enable innovation and interoperability, and continue to deliver on the promise of the IoT for every stakeholder.”
Dotdot is the Zigbee Alliance universal language for the IoT, making it possible for smart objects to work together on any network. Thread is the Thread Group mesh networking technology for IoT products. These two organizations have come together to deliver a solution for IoT interoperability that isn’t confined to single-vendor ecosystems or technologies.
Delivering on the Promise of the IoT
The early internet faced the same challenges as IoT today. Currently, connected devices can struggle to deliver a seamless experience because they speak different languages (or in technical terms, use different application layers). For the internet, the industry solved this problem with open, universal protocols over IP. The Dotdot common device language over the Thread IP network extends this same approach to the Internet of Things. With Dotdot over Thread, product and platform vendors can ensure the interoperable user experiences needed to drive growth, while IP allows vendors to maintain a direct connection to their device and their customers.
Product Development with Mature Technologies and Diverse Supply Chains
It’s important to note that Dotdot over Thread is not another new standard. Dotdot enables the application layer at the heart of Zigbee to work across the Thread IP network, the same network technology fundamental to the internet. For product managers, new standards represent risk. Dotdot and Thread are backed by global companies and represent two well-supported connectivity and interoperability technologies, driving billions of products and networks already in homes and offices.
“Zigbee and Dotdot are the product of 15 years of innovation by our members, and the experience that comes from over a decade of building products,” says Tobin Richardson, Zigbee Alliance president and CEO. “This maturity is why technology leaders have chosen ZigBee, and Dotdot over Thread now brings that value to new markets. This marks the first of many partnerships to come as we extend our application layer across additional networks to accelerate time to market and unify the IoT for all stakeholders.”
“The Thread Group vision is to extend IP to low-power IoT devices,” says Grant Erickson, president of the Thread Group. “Just like the internet, this vision also requires the industry to put forth common protocols so devices from any vendor can work together. Dotdot gives Thread adopters an option for that open, end-to-end connectivity and interoperability.”
How to Start Working with Dotdot over Thread
The Dotdot specification is available to Zigbee Alliance members. Additional resources, including the Dotdot Commissioning Application, will be available in Summer 2018, along with the opening of the Dotdot Certification program from the Zigbee Alliance. Thread launched its 1.1 specification and opened its certification program in February 2017. The Zigbee Alliance and Thread Group share a number of common authorized test service providers, and are working with them to ensure a seamless certification process for Dotdot over Thread adopters. More information on this program will be announced soon.
