802.11ax vs 802.11ac - Which Wi-Fi Standard is Better?

With the increasing demand for faster and more reliable wireless networks, the development of new Wi-Fi standards has been essential. Two of the most widely discussed standards are 802.11ax and 802.11ac. Let's explore the differences between these two standards and find out which one is superior.

802.11ac - The Current Wi-Fi Standard

802.11ac, also known as Wi-Fi 5, has been widely adopted since its introduction in 2014. It operates on the 5GHz frequency band and offers significant advantages over its predecessor, 802.11n. With multiple-input and multiple-output (MIMO) technology, 802.11ac provides faster speeds, higher capacity, and improved network performance. Theoretically, it can reach speeds of 1.3 Gbps (gigabits per second) under optimal conditions, offering seamless support for activities like video streaming and online gaming.

Additionally, 802.11ac introduced wider channels, up to 160MHz, which allow for higher data rates. Moreover, it utilizes beamforming, a technique that improves signal strength and range by directing the wireless signals directly to connected devices. Beamforming also helps to minimize interference and improve overall network stability.

802.11ax - The Next Generation Wi-Fi

802.11ax, also known as Wi-Fi 6, is the latest standard in wireless networking. Released in 2019, it aims to overcome the limitations of its predecessors and deliver an even better wireless experience. One of the prominent features of 802.11ax is the introduction of orthogonal frequency-division multiple access (OFDMA), which allows for more efficient data transmission by dividing the wireless channel into smaller sub-channels or resource units.

OFDMA enables multiple devices to connect simultaneously and enjoy consistent performance, even in dense environments. This is particularly beneficial for crowded areas like stadiums or airports. Additionally, 802.11ax operates on both the 2.4GHz and 5GHz frequency bands, improving compatibility with a wider range of devices.

Another significant improvement in 802.11ax is the use of target wake time (TWT) technology, which enhances battery life for connected devices by optimizing their sleep and wake patterns. This ensures efficient power usage, especially in Internet of Things (IoT) environments where numerous devices need to connect and transmit data.

Which One Is Better?

While both standards offer significant improvements over their predecessors, 802.11ax (Wi-Fi 6) has the edge over 802.11ac (Wi-Fi 5) in terms of overall performance and future-proofing your network. Wi-Fi 6 provides faster speeds, increased capacity, lower latency, and better stability, which is crucial in an era where multiple devices heavily depend on wireless connectivity.

However, it's important to note that in order to fully enjoy the benefits of 802.11ax, you need compatible devices such as smartphones, laptops, or routers that support the standard. Upgrading your entire network infrastructure may require some investment, but it will undoubtedly deliver a better wireless experience, especially in high-density environments.

In conclusion, 802.11ax (Wi-Fi 6) stands as the superior choice for achieving unparalleled wireless performance, while 802.11ac (Wi-Fi 5) remains an excellent option for those with existing infrastructure. As technology continues to evolve, wireless standards will continue to advance, ensuring faster and more reliable Wi-Fi networks for all.
