Software-Defined Wireless Networking (SDWN) is the use of SDN concepts in wireless networks. By using a controller in the control plane, SDWN facilitates the creating of a new adaptive mechanism according to different applications and user demands, such as mobility (handoff), security, and quality of service (QoS).
Software-Defined WiFi is a new way of thinking about networking in which the control plane is separated from the data plane. It relies on commodity hardware and software components and can be used to implement advanced features over existing wireless infrastructure.
