embedded world 2019 What is openD? • openD is Wireless Voice and Data on one platform


• openD is an open source set of APIs that enable DECT & ULE to work seamlessly with prototyping platforms like Raspberry-Pi and ST Nucleo


• openD will provide source code for all APIs and sample code for each of the enabled use case scenarios


• openD is the developer community around DECT and ULE D Background


ECT has long since ceased being just a cord replacement for the home phone. Its proliferation in other market segments means DECT can be seen in everything from communication to healthcare and industrial applications. Since the introduction of ULE in 2013, the smart home is now a key target segment using low powered sensors controlled via the home gateway.


This transformation in the applications base also brings new challenges and technical requirements for the technology. To meet these, the DECT Forum and ULE Alliance have submitted DECT as a proponent 5G(IMT-2020) technology and will upgrade the technical specifications to fulfill the requirements of new 5G application markets.


Coupled with this upgrade, DECT Forum


has created openD, an open source API that enables developers in those vertical


Tooling: openD uses open source design tools:


markets to create applications that profit from the integration of DECT and ULE.


openD Developer Community openD is not only an open source API for wireless application development. It also identifies the community ideas, applications and products based on the DECT/ULE air interface.


openD will be posted on the public domain to inform and keep the developer community invested in the progress of its development. We welcome feedback via our community Blog or via GitHub where the code and software specification reside.

The openD build system uses Cmake and provides:


• Options for application and platform • Debug and Release configurations • Unit tests


• Doxygen documentation openD Toolchains:


• arm-none-eabi


• arm-linux-gnueabihf openD Debugger: • OpenOCD


openD Code Editor:


• Visual Studio Code (VS Code) Windows, Linux, Mac


Functionality: openD is a living product. While it grows with your requests,


improvements and recommendations, openD will be shaped into a wireless interface that really adds value for application developers globally. In time we expect to see many target applications in industrial, audio and smart home driving our roadmaps and release plans. The first release will showcase the


strengths of DECT and ULE technologies featuring some key technology benefits for various application areas. Here are some of the features:


Audio Link


• Voice and Data on one wireless platform


• Call initiated by HAN FUN (Home Access Network, Functional Protocol)


• Creates a direct audio link at the push of a button with the fixed part initiating the connection


• Create robust high quality Audio links using the long range (50M indoor/300M


outdoor) and low power consumption of ULE


• Build pageable devices like pendants to solve the growing issues of remote care and vital signs control/alarm


Full Duplex voice communication


• Full duplex connection from fixed to portable part initiated by the telephony interface


• Typical associated applications: door communication/opening devices, baby- phones, bi-directional audio monitors etc


Smart Home/Building sensors for voice and data communication in the Home/Building Network


• Build the Internet of things at home with native connectivity to home gateways using the integrated DECT base station


• Wireless Sensor type communication switches for lights, dimmers, window and door locks


• Speaking smoke alarms and thermometers (using Nucelo to store and play the message)


• Create the next generation of devices for industrial automation and healthcare that profit from an uncluttered radio spectrum band.
