One-third of global Wi-Fi networks still on Wi-Fi 4, limiting speeds of latest phones
About one-third of Wi-Fi networks worldwide still rely on Wi-Fi 4, a standard introduced in 2009, a survey showed. Ookla said 33.2 percent of global Wi-Fi networks use Wi-Fi 4-based equipment, while Wi-Fi 5 accounts for 38.3 percent and Wi-Fi 6 for 26.7 percent. Wi-Fi 7 stands at 1.8 percent. Older routers cannot use the 6 GHz band, which can worsen congestion and performance in dense areas.
