• Acronym: MultiRat-Coord
  • Short description: Driven by the growing number of connected devices, the coordination and coexistence of heterogeneous wireless technologies such as LTE, WiFi as well as 5G has become a key research area today. The MultiRat-Coord prototyping system focuses on the joint real-time experimentation of LTE and WiFi systems utilizing a single software-defined radio platform.  Additionally, a 5G GFDM link is available using the same hardware. This platform allows new experimentation results that will lead to a better understanding of the trade-offs when using different radio access technologies together as it would be the case in practical wireless network deployments.
