WiFi 7 is here. What are the improvements compared to WiFi 6?

WiFi 7 has become one of the hottest topics, especially after Qualcomm, H3C and other manufacturers released WiFi 7 commercial solutions, the discussion about WiFi 7 has exploded again. So, what are the significant improvements of WiFi 7 compared to WiFi 6? For ordinary home users, do they need to upgrade to WiFi 7 now?

First, the wireless transmission rate of WiFi 7 has been greatly improved, jumping from 9.6Gbps of WiFi 6 to 30Gbps. This is mainly due to the expansion of frequency bands and wireless channels, as well as the upgrade of modulation methods.

WiFi 7 incorporates the 6GHz frequency band dedicated to WiFi 6E into the regular frequency band based on 2.4GHz and 5GHz. From the perspective of wireless channels, WiFi 7 uses 320MHz channels, which is double the 160MHz of WiFi 6. In terms of modulation, WiFi 7 uses 4096-QAM, while WiFi 6 uses 1024-QAM.

However, according to user feedback, WiFi 6 does not significantly improve the user experience compared to WiFi 5, and the network speed does not reach the advertised data. Therefore, WiFi 7 is of little significance to ordinary home users. It is mainly aimed at high-speed intranet transmission and AR/VR scenarios. Users with NAS can access stored data faster through WiFi 7. For AR/VR devices, lower latency and richer data experience can be obtained.

In general, WiFi 7 has little impact on ordinary users in the early stage. However, it brings new possibilities for scenario-based applications in various industries, such as industrial Internet and telemedicine. Ordinary home users do not need to follow the trend and replace WiFi 7 devices, but WiFi 7 has greater significance for industrial users.
