Which wireless standard has the highest data transfer rates currently?

  1. 802.11g

  2. 802.11n

  3. 802.11ac

  4. 802.11ax

The correct answer is: 802.11ac

The wireless standard known for having the highest data transfer rates currently is 802.11ax, also referred to as Wi-Fi 6. While 802.11ac (Wi-Fi 5) significantly improved upon previous standards like 802.11n (Wi-Fi 4), offering data transfer rates of up to 3.5 Gbps under optimal conditions, 802.11ax takes performance even further. It can achieve theoretical maximum speeds of up to 9.6 Gbps. 802.11ax not only increases speed but also improves efficiency and performance in environments with many connected devices. This is particularly important in today's world where households and businesses may have numerous devices vying for bandwidth. Features such as Orthogonal Frequency Division Multiple Access (OFDMA) allow for better distribution of bandwidth, making it more efficient in high-density areas. The other mentioned wireless standards, 802.11g and 802.11n, lag behind in comparison. 802.11g supports up to 54 Mbps and 802.11n can reach up to around 600 Mbps, which is significantly lower than what 802.11ac and 802.11ax offer. Thus, for the highest data transfer rates, 802
