Which standard is known as Wi-Fi 4?

Explanation:
Wi-Fi 4 refers to the 802.11n standard. It introduced MIMO (multiple input, multiple output) to boost data throughput and allowed channel bonding up to 40 MHz, enabling higher speeds. It operates in both 2.4 GHz and 5 GHz bands, with theoretical speeds up to about 600 Mbps when using four spatial streams and 40 MHz channels. This distinguishes it from the other generations: 802.11ac is Wi‑Fi 5, 802.11ax is Wi‑Fi 6, and 802.11b is Wi‑Fi 1.
