Which technology is primarily used to connect devices wirelessly in a local area network?

Wi-Fi is the technology primarily used to connect devices wirelessly in a local area network (LAN). It allows multiple devices such as smartphones, laptops, tablets, and other smart devices to communicate with each other and access the internet without the need for cables. This wireless connectivity is facilitated through radio waves, enabling greater flexibility and mobility compared to wired connections.

Wi-Fi operates according to established standards that ensure interoperability between different devices and manufacturers, making it widely adopted for home and business networking. This technology has evolved over time with various standards (such as 802.11a/b/g/n/ac/ax), improving speed, range, and network efficiency.

Other options like Ethernet are primarily known for wired connections, while Bluetooth is designed for short-range device communication rather than a broader local area network. Token Ring is an older networking technology that uses a specific token-passing protocol, which has largely been replaced by more modern technologies like Ethernet and Wi-Fi.
