Wi-Fi

Wireless Local Area Networks (IEEE 802.11)

• Transmits data between workstations and local area networks using high-speed radio frequencies.
• Current technologies support up to 1000 Mbps (theoretical) data transfer at distances up to hundreds of feet.
• Popular standards include IEEE 802.11b, a, g, n, ac, and ax.
