What is a domain in the context of Wi-Fi connections?
A domain in Wi-Fi connections refers to a specific area or range within which a device can connect to a wireless network. It is defined by the characteristics of the network itself, such as its SSID (Service Set Identifier), frequency bands, and the authentication required to join the network. Each Wi-Fi domain may serve a distinct geographic area or a separate network service.
When a device connects to a Wi-Fi domain, it enables communication between the device and the access point or router within that domain. This connectivity allows users to access the internet or local resources like printers and servers, making it essential to understand the limits and capabilities of each Wi-Fi domain, especially in environments like offices or large public areas where multiple domains may exist.
