Optimizing Wireless Resources in 802.11ac And Beyond

The extremely fast growing wireless data demand has fueled the interest in improving Wi-Fi network capacity. Since spectrum resources are ultimately limited, serving more users and applications within existing resources has been the driving factor for research and innovation in this field. In this paper, we investigate how to exploit spectrum efficiency to address the needs of upcoming and future Wi-Fi networks. We present our view on the future Wi-Fi landscape with respect to market and technology trends. We then evaluate recent technology improvements and discuss upcoming advances to show the significance of these technologies for the future of Wi-Fi.
