Optimizing Wi-Fi (802.11x)-based connectivity

Wi-Fi was designed to allow laptops, smartphones, and tablets to connect to the internet and/or communicate with each other on a local area network (LAN). It uses RF to transmit data over relatively short distances, typically within a home or office – although permutations intended for outdoor use are becoming more common.

Wi-Fi is based on the IEEE 802.11 standards, which operate at Layer 1 of the OSI model (physical). Introduced in the late 1990s, it was the first commercially successful wireless networking technology that was designed to work seamlessly with Ethernet (IEEE 802.3) – which almost all LANs use at Layer 2.
