What can we expect from Wi-Fi 6?

Wi-Fi 6 is built on the success of Wi-Fi 5 (802.11ac) and boasts a great leap in spatial reuse efficiency through enhanced coding and scheduling. With Wi-Fi 6, each AP can simultaneously communicate with more devices and allow higher-density deployment, reduced delays, larger coverage, and higher speeds. Moreover, performance improvement brought by Wi-Fi 6 prolongs battery life and is particularly friendly to the battery-based Internet of Things (IoT) devices.

With improved efficiency, flexibility, and scalability, Wi-Fi 6 enables a faster speed and a larger capacity for next-generation advanced applications, such as seamless mobile roaming, 4K or 8K videos, high-definition collaboration applications, all-wireless office, IoT, and even applications in high-density environments.

Wi-Fi 6 will soon be applied to scenarios of conferences with tens of thousands of users, high-density office, wireless production, smart teaching, smart media, digital cities, and enterprises with revolutionary user experience enhancement.

How does Wi-Fi 6 enhance the user experience?

Wi-Fi 6 enhances user experience via the following technical features:

Higher-order modulation scheme (1024-QAM), more subcarriers, and lower inter-frame space overheads: With these technologies, Wi-Fi 6 increases a theoretical maximum connection rate (in a case of a 160 Mbps bandwidth and 8 spatial flows) from 6.9 Gbps to 9.6 Gbps.

Multi-user transmission: namely, the uplink/downlink multi-user multiple-input multiple-output (MU-MIMO) and uplink/downlink orthogonal frequency division multiple access (OFDMA), which can increase the concurrency capability and the average terminal rate in high-density deployment scenarios.

Basic service set (BSS) coloring: Improves the interference immunity of wireless systems.

Target wakeup time (TWT): Enables better power saving and management.

The following uses road traffic as an example to describe in detail how Wi-Fi 6 enhances user experience. In this example, a road is equivalent to a frequency band for Wi-Fi, with limited and fixed frequency band resources, and vehicles on the road are like packets varying in size and transmission rate.


Quadrature amplitude modulation (QAM) is a two-dimensional lattice modulation scheme that converts a data signal “01” into a radio wave.

Wi-Fi 6 supports 1024-QAM (2^10 bits/symbol) and has its modulation capability increased by 25% compared to that of 256-QAM (2^8 bits/symbol) supported by Wi-Fi 5. This improvement is like road optimization. That is, on one road, we can narrow down the lane width to have more lanes, without causing traffic chaos.
