We present Wi-5, a spectrum programming architecture for radio resource management in unlicensed frequency bands. It introduces a spectrum control plane that offers fine grained allocation of radio resources, flexible configuration of radio and wireless networking parameters, and continuous monitoring of the wireless network status. These features, along with the centralized nature of this architecture, can effectively address spectrum congestion which often occurs in unlicensed frequency bands. To demonstrate Wi-5’s capabilities, we show results obtained from emulating various use case scenarios on our open source proof-of-concept.
