ARIADNE White Paper ““On communication-theoretic models for programmable wireless environments enabled by reconfigurable intelligent surfaces”
The ARIADNE project has just published its White Paper entitled “On communication-theoretic models for programmable wireless environments enabled by reconfigurable intelligent surfaces”.
With the current deployment of the fifth generation (5G) of communication systems, it is now a critical time to identify enabling technologies for the sixth generation (6G) of communication systems. 6G systems are expected to fulfill more stringent requirements than 5G systems, on transmission capacity, reliability, latency, coverage, energy consumption, and connection density. Existing 5G technologies, such as millimeter-wave communications, massive multi-input multi-output systems, ultra-dense heterogeneous networks, are mainly focused on the system design at the transmitter and receiver sides, and on the deployment of additional network infrastructure with power amplification and digital signal processing capabilities and backhaul availability. The purpose of currently available 5G technologies is mainly to cope with or to capitalize on often-unfavorable wireless propagation environments. In fact, the wireless environment has been conventionally modeled as an exogenous entity that cannot be controlled but can only be adapted to. According to this design paradigm, communication engineers usually design transmitters, receivers, and transmission protocols based on the specific properties of the wireless channels and for achieving desired and target performance.
