The primary purpose of the IEEE 802.11 standard is to define protocols for implementing wireless local area networks (WLANs), commonly referred to as Wi-Fi. This standard ensures consistent communication among devices over wireless connections, facilitating seamless data transmission between computers, smartphones, and other equipment in homes and businesses. It establishes technical specifications like frequency bands, modulation techniques, and security protocols, enabling interoperability of devices regardless of manufacturer. By providing a framework for reliable wireless connectivity, IEEE 802.11 has revolutionized how people access and share information globally.
