A software defined open Wi-Fi platform

Wireless local area network (WLAN) is an indivisible part of the next generation wireless system. In this paper, an open Wi-Fi platform is designed and developed with special consideration of real-time signal processing. Such system can help accelerate research and development of future wireless network, especially in the case of cellular/ Wi-Fi co-existing networks. This platform is based on the Intel general-purpose processor and the universal software radio peripheral (USRP) radio front end. The design including the physical layer implementations is purely software and is optimized for real-time signal processing on the general purpose processor. In the lab experiment, this platform supports baseband rate up to 700 Mbps with 2 transmitters in 80 MHz bandwidth. A cellular-Wi-Fi signaling interface between the Wi-Fi access point (AP) and the 5G core network is also developed and validated as an example for wireless resource allocation.
