Closing the loop in unlicensed spectrum: Challenging real-time sensor networks

Wireless sensor networks are used in a wide variety of applications in a best effort way. This is possible as for most applications reliability is not critical, and failures only cause a slight inconvenience to the user. Next generation wireless systems, researched under the 5G agenda, will be required to address the need for low latency and highly reliable (up to 5 nines) machine to machine communications. This demo will show a practical implementation of such a system built using Software Defined Radio technologies. The radio link will be used to balance a robot on two wheels, which is impossible when a lot of packets are lost and delayed. The reliable protocol can be challenged interactively by a human opponent. Who knows how to beat the reliable protocol and make the robot fall?
