Institute of Electrical and Electronics Engineers (IEEE) wireless Wi-Fi 6 (802.11ax) standard is the successor to the IEEE Wi-Fi 5 (802.11ac) standard. Wi-Fi 6 addresses the increasing number of devices in individual networks. Wi-Fi 6 operates in the 2.4 GHz and 5 GHz bands and features improvements in throughput, multiple-device support, and Wi-Fi spectrum efficiency. The following are major features of Wi-Fi 6:
Efficiency and capacity improvements
• Orthogonal Frequency-Division Multiple Access (OFDMA). This feature enables your router and devices to use your bandwidth more efficiently by reducing the time between data transmissions. As a result, more bandwidth is available for other devices. For example, the RAX200 supports several client devices per WiFi band with downlink and uplink OFDMA technology.
• High-bandwidth traffic efficiency with 8-stream Multi-User-Multiple-Input Multiple-Output (MU-MIMO). This technology enables your router to communicate with many devices simultaneously. Wi-Fi 6 also allows 8x8 APs to use all eight streams to transmit information.
Note: Downlink MU-MIMO is not new in Wi-Fi 6.
Speed improvements
• Improvements in data speeds and signal encoding. Wi-Fi 6 enables devices to send more data in one transmission, resulting in speed improvements of up to 20%.
• Improvements through higher order modulation (1024-QAM). Higher order modulation increases the efficiency and speed of data transmission on your network. This technology can give up to 25% improvements in speed.
Together, these two features provide up to 40% improvement in connection speeds.
Range improvements
• 20MHz-only devices and OFDMA’s ability to use smaller subcarriers means such devices can reach longer distances.
Future improvements
• Further improvements through uplink MU-MIMO. Uplink MU-MIMO allows more of your devices to transmit data to your AP, improving network efficiency.
• Better neighborhood, urban, and city-wide WiFi through spatial re-use (BSS color). BSS coloring enables devices operating in the Wi-Fi 6 standard to differentiate between signals from their own network and signals from other networks. This feature increases the efficiency and capacity of your network.
• Extended battery for mobile and smart home devices with Target Wake Time (TWT). TWT makes communication between your devices and your router’s Wi-Fi channels more efficient. Devices that support TWT enter a sleep state until their scheduled wake time. TWT reduces energy consumption and bandwidth use.
• 6 GHz spectrum. The development of a 6 GHz band in the future means more unlicensed bands available for high-bandwidth applications.
Note: Not all features are available in all products. Please refer to individual product documentation for more details.
