What does the 802.11 specification define?

The 802.11 specification is crucial as it establishes the wireless networking standards that enable communication between devices using Wi-Fi technology. This specification outlines various aspects, including the radio frequencies used for transmission, modulation techniques, and physical layer protocols, which are essential for enabling wireless communication in local area networks (WLANs).

Essentially, 802.11 creates a framework that allows devices such as laptops, smartphones, and routers to connect and communicate over wireless networks effectively. It plays a vital role in defining how data is transmitted and received over radio waves, thereby facilitating the connectivity we rely on for internet access and local networking in both personal and business environments.
