What is the latest evolution in wireless networks that supports 2.4 GHz, 5 GHz, and 6 GHz frequency bands?

The correct response identifies 802.11ax as the latest evolution in wireless networking technology that operates on the 2.4 GHz, 5 GHz, and 6 GHz frequency bands. This standard, commonly referred to as Wi-Fi 6, builds upon its predecessors by enhancing overall network efficiency, capacity, and performance, particularly in environments with multiple connected devices.

One notable feature of 802.11ax is its ability to utilize the 6 GHz band, which significantly expands the available bandwidth for wireless communications. This expansion helps alleviate congestion that can occur in the 2.4 GHz and 5 GHz bands, allowing for improved speeds and reduced latency for users. Additionally, 802.11ax incorporates advanced technologies such as Orthogonal Frequency Division Multiple Access (OFDMA), which enables more efficient data transmission by allowing multiple users to share channels simultaneously.

While Wi-Fi 6 is indeed synonymous with 802.11ax, specifying the latter emphasizes the technical standard itself. Other options like 802.11ac and Multi-User MIMO do not represent the latest technology that encompasses all three frequency bands, as 802.11ac primarily supports only the 5 GHz band and does not include the advancements and capabilities found in 802.
