Triangle announces the third Open Call for experimenters to use the Triangle Testbed. This is an excellent opportunity for App makers, IoT and device makers to get early access to this testing and certification platform. In addition to test automation under a wide range of configurable network scenarios, our recently added and upcoming testbed “extensions” provide a range of opportunities for testing AR/VR and streaming applications. The Testbed can support a wide variety of application and device types, here are some examples of the types of experiments that have already been run on the Testbed. The first wave of this call closes on March 11th. For more details see open call or feel free to get in touch with us at opencall@triangle-project.eu.
