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.

Hanwha Vision said on Monday it launched a corporate social responsibility project, Vision Zone, to support safety infrastructure such as AI security cameras at residential facilities for disabled infants and toddlers. The first beneficiary is Choroknamu, a facility in Changwon, South Gyeongsang province, home to about 40 infants, toddlers and children with intellectual, developmental and brain lesion disabilities. The support includes about 30 cameras, storage devices and monitors, with free maintenance without a time limit.
