Abstract
New technologies continue to be introduced for WLAN applications at a robust pace. We review the value proposition for some of the key features of 802.11ac such as larger bandwidth, higher order modulation, and MIMO and MUMIMO transmission modes, explaining how each feature translates to improved user experience. We present channel measurements and prototype performance data to demonstrate the gains of MIMO and MU-MIMO in an indoor environment. Next, we discuss the value proposition of some key features of 802.11ah. Measurement data of 802.11ah performance is provided, showing how it is a compelling technology for the growing Internet of Things market. We conclude with a preview of emerging technologies that promise to improve user experience — 802.11ai for fast network acquisition and 802.11ax for high-efficiency networking in dense indoor and outdoor networks.
