Wi-Fi standards have evolved significantly, offering various speeds and ranges. Starting with 802.11a (5 GHz, up to 54 Mbps) and 802.11b (2.4 GHz, up to 11 Mbps), the technology progressed to 802.11g (2.4 GHz, up to 54 Mbps) and 802.11n (Wi-Fi 4, dual band, up to 600 Mbps). Wi-Fi 5 (802.11ac) operates at 5 GHz with speeds up to 3.5 Gbps, while Wi-Fi 6 (802.11ax) enhances efficiency and speed up to 9.6 Gbps across 2.4 GHz and 5 GHz bands. The upcoming Wi-Fi 7 (802.11be) promises speeds exceeding 30 Gbps across 2.4 GHz, 5 GHz, and 6 GHz bands. For security, WEP is outdated and insecure, while WPA offers medium security. WPA2, using AES, is widely adopted for its high security, and WPA3 provides very high security with advanced features against brute-force attacks. Each standard and encryption method caters to different needs, ensuring robust and secure wireless connectivity.
