DSR Corporation Developing DECT NR+ Stack to Support Scalable IoT, Pro-Audio and Industrial Use-Cases

DSR Corporation (DSR), a global leader in embedded and wireless software development, today announced it has begun development of a DECT NR+ protocol stack designed to enable scalable, secure and interoperable wireless connectivity for massive IoT and industrial automation deployments. DSR brings more than twenty years of experience in wireless protocol stack development, including development of the ZBOSS Zigbee PRO stack and co-founding the ZBOSS Open Initiative (ZOI), a collaborative member-source community that brings together semiconductor vendors, device makers, and other ecosystem participants to work on a common Zigbee PRO software platform. 

“We see DECT NR+ as enabling a new class of wireless deployments that require scalability, ultra-low latency, and interoperability,” said Anatoli Pechkov, CEO of DSR Corporation. “With decades of experience in wireless protocol stack development, we are building the stack to support demanding use cases in building automation, Pro-Audio, and industrial environments, while establishing a community model that enables easy adoption.”

From an ecosystem perspective, this type of stack development is critical to accelerating adoption of NR+ as new member of the DECT family of standards,” said Christian Schepke, Chairman of the DECT Forum. “We welcome DSR’s work providing a strong technical foundation for companies looking to develop interoperable, next-generation wireless solutions.”

The DECT NR+ stack is in development with a hardware-agnostic architecture, enabling migration between hardware platforms with minimal effort. The architecture also allows for flexible distribution of stack layers between the network processor and the host processor, supporting different system designs and deployment requirements. Additionally, DSR is establishing an DECT NR+ network simulation platform to accelerate protocol development and support rapid prototyping and validation of large-scale deployments.

The stack is designed as a multipurpose solution, configurable to support multiple use cases, including Building Automation, Pro-Audio, and Industrial applications with ultra-low latency.

As part of its long-term goal, DSR is designing the DECT NR+ stack to support large-scale deployments, including configurable network topologies such as cluster tree, mesh, and star. The stack is intended to support IPv6 networks comprising thousands of devices, with security aligned with the latest EU regulatory standards. The stack design and architecture are well positioned to accommodate transport-layer support for protocols such as Matter and KNX.

For Pro-Audio and other ultra-low latency applications, the DECT NR+ stack is designed to enable streaming with less than three milliseconds of network latency for devices operating in star topology networks, along with resistance to carrier radio issues through smart carrier sensing and transmission mode selection algorithms.

DSR intends to advance the DECT NR+ stack through an adopter‑driven community model extending the ZBOSS Open Initiative, fostering collaboration on a unified platform that accelerates development, lowers R&D investment, and improves product interoperability. The ZBOSS Open Initiative is a market‑proven member‑source model successfully operated by DSR since 2020, with dozens of active members. Participation in the DECT NR+ community will follow this proven structure through annual membership, with fees reinvested into continued stack development and technical support. Community members will receive access to the source code and licensing rights for stack usage with no royalties or per‑copy fees. While the software stack itself is provided on a royalty‑free basis, DECT NR+ is a standardized technology that may be subject to Standards Essential Patents (SEPs), and implementers and device manufacturers remain responsible for complying with any applicable SEP licensing obligations associated with the standard.

DSR brings extensive experience in wireless and embedded systems development, including the development of five protocol stacks and experience working with eight different wireless technologies. The company understands the full solution scope from the embedded stack through cloud and user applications, and maintains strong connections with potential technology stakeholders and industry partners, enabling effective knowledge exchange as development progresses.
