Wi-Fi 6
The Next Evolution of Wi-Fi technology
Wi-Fi 6 Quick Facts
6th Gen
802.11ax is the 6th generation of Wi-Fi, and will be known simply as “Wi-Fi 6”
4x Capacity
The new standard will have quadruple the capacity for more devices than 802.11ac
IoT Optimized
Wi-Fi 6 supports flexible channel sizes and resource units that allow operators to offer more efficient IoT support
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.
