    en.wikipedia.org/wiki/Wi-Fi_6

    Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks ( WLANs ). It operates in the 2.4 GHz and 5 GHz bands, [ 9] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [ 10] It is an upgrade from Wi-Fi 5 ( 802.11ac ), with improvements for better performance in crowded places.

    Wireless ad hoc network. A wireless ad hoc network[ 1] ( WANET) or mobile ad hoc network ( MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes.
