Wi-Fi 6The Now of Networking
What is Wi-Fi 6?
The new generation of Wi-Fi technology, Wi-Fi 6, offers a paradigm shift at the network edge: not just faster speeds as in previous generation changes, but a shift to high-efficiency Wi-Fi for substantially improved capacity, better coverage and reduced network congestion, using key technologies such OFDMA and Uplink and Downlink MU-MIMO
