Wi-Fi 6 (IEEE 802.11ax) is the latest iteration of the wireless standard, aiming to address the growing demand for data connectivity and bandwidth. It offers substantial improvements over its predecessor, Wi-Fi 5 (802.11ac). 

Just as 5G revolutionizes mobile networks, Wi-Fi 6 is set to transform our wireless internet experience.

Key Differences Between Wi-Fi 6 and Wi-Fi 5

Beyond speed, Wi-Fi 6 excels in supporting more devices without compromising performance. It offers four times the bandwidth of Wi-Fi 5, ensuring that network speeds remain stable even as more devices connect.

Wi-Fi 6 achieves this efficiency through two key technologies: MU-MIMO and OFDMA.

MU-MIMO (Multi-User, Multiple-Input, Multiple-Output)

MU-MIMO allows multiple devices to connect to a router simultaneously. Wi-Fi 5 supports up to four devices, whereas Wi-Fi 6 expands this capability to eight devices. Think of it as having more delivery trucks to distribute goods, enhancing efficiency.

OFDMA (Orthogonal Frequency Division Multiple Access)

OFDMA takes the concept further by enabling a single truck to deliver goods to multiple locations at once. This technology allows data packets to be sent to various devices simultaneously, optimizing network performance.

Advantages of Wi-Fi 6

While speed and device capacity are significant, Wi-Fi 6 offers other crucial benefits:

• Enhanced Security: Wi-Fi 6 introduces WPA3 (Wi-Fi Protected Access version 3), a security protocol that encrypts connections and protects against brute-force attacks, even with weaker passwords. Although some non-Wi-Fi 6 devices support WPA3, it becomes a standard requirement with Wi-Fi 6.
• Higher Data Capacity with 1024-QAM: Wi-Fi 6 utilises 1024-QAM (Quadrature Amplitude Modulation), which increases data capacity and improves speeds by 25% over Wi-Fi 5’s 256-QAM.
• Reduced Wi-Fi Conflicts with BSS Color: BSS (Basic Service Station) Colour helps mitigate interference from neighbouring networks by marking other networks and causing the router to ignore them, reducing signal conflicts.
• Improved Battery Life: Wi-Fi 6 features Target Wake Time, which schedules when devices check in with the router, conserving battery life by reducing the need for constant wake-ups.

Future-Proofing Your Network

Adopting Wi-Fi 6 is a way to future-proof your network. As more devices become Wi-Fi 6 compatible, having a Wi-Fi 6 router will ensure you can take full advantage of the capabilities of these new devices. Additionally, even non-Wi-Fi 6 devices can experience improved performance on a Wi-Fi 6 network due to better traffic management and reduced congestion.

Upgrading to Wi-Fi 6

To experience the benefits of Wi-Fi 6, both your devices and your router need to be Wi-Fi 6 certified. Similar to requiring Bluetooth 5.0 compatible devices for a phone with Bluetooth 5.0, both ends of the connection need to be Wi-Fi 6 capable to leverage its advantages.

Wi-Fi 6 represents a significant advancement in wireless technology, providing faster speeds, superior capacity for handling multiple devices, and improved efficiency. As the number of internet-connected devices continues to rise, Wi-Fi 6 is well-positioned to meet the growing demands for reliable and high-performance wireless connectivity.
