In general, a switch cannot provide Wi-Fi connectivity directly, because a switch is essentially a network device used to connect multiple network devices in a local area network.
However, modern switches often have some additional features, such as support for management vlans (virtual local area networks), which can build wireless networks with vlans. In addition, some advanced switches can also be integrated with Wi-Fi controllers to provide Wi-Fi services to improve network efficiency and security.
Still, if a Wi-Fi network needs to be provided, then the best option is to use a specialized wireless router or access point (AP). These devices are designed to create a stable, secure, and easy-to-manage wireless network environment that includes many WiFi-related features such as SSID broadcasting, encryption, user authentication, and more.
