Wi-Fi 7: What are the differences between Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7
Wi-Fi 7 is the latest Wi-Fi network communication protocol. This technology not only achieves higher transmission speeds and lower delays, but also meets more diverse application scenarios, such as augmented reality (AR) and virtual reality. Reality (VR), games and cloud computing, etc., it expands on the basis of its predecessors Wi-Fi 6 and Wi-Fi 6E, significantly improving response capabilities and reliability. Its main new features include 320 MHz channels, 4K QAM, MLO (Multi-link Operation), Multi-RU (Resource Units) and Puncturing, etc.
There are not enough devices supporting Wi-Fi 7 and compatibility on the market
Since Wi-Fi 7 chips have just been launched in Q4 of 2023, there are not many wireless network devices on the market that support Wi-Fi 7. Most of them are wireless network cards, mobile phones, wireless routers and other products. We purchased some devices supporting Wi-Fi 7 through overseas regions, including Intel BE200NGW wireless network card, ASUS ROG Phone 7 mobile phone, Google Pixel 8 Pro mobile phone, TP-Link Deco BE85 AP, TP-link BE19000 AP, ASUS RT- BE96U AP and NETGEAR Orbi 970 AP. After actually connecting these devices, I found that ASUS ROG Phone 7 can only connect to the wireless router in 802.11 ax (Wi-Fi 6) mode, but cannot connect in Wi-Fi 7 specifications. It can be connected to Google Pixel 8 Pro In terms of online performance, the connection was smooth and there were no problems. Although the hardware specifications of currently commercially available products support the latest standards, the software part may not be fully supported. In the future, updates will be required to support Wi-Fi 7, or chip compatibility issues may occur with other products. This may result in the inability to connect
Wi-Fi 7 performance: Tested on Wi-Fi 7 routers, mobile phones and gaming laptops
Next, we used the TP-link BE19000 tri-band Wi-Fi 7 router to test the speed of Wi-Fi 7 with the Google Pixel 8 Pro mobile phone and the Lenovo Legion series gaming laptop. In order to ensure that there is no interference from other wireless signals that will affect its transmission performance, we chose to conduct it in a wireless shielded room. The test items include uploaded and downloaded data in the supported 2.4GHz/5GHz/6GHz frequency bands and different bandwidths.
Test Result
First of all, Allion takes you to see the performance of devices in the 2.4GHz frequency band. Because the 40MHz bandwidth of the mobile phone does not support Wi-Fi 7, there is no corresponding test data. The actual upload and download speeds are not much different from Wi-Fi 6. However, the value that can reach 500Mbps on the Lenovo system is very good.
Next, we will take you to understand the performance on the 5GHz band. When the bandwidth is 80MHz, both devices can reach 1000M speed, and when the bandwidth is 160MHz, they can reach 2G speed. The performance of the Notebook will be slightly better than that of the mobile phone. One thing is normal. If you want to download a high-definition video, it can be completed in almost one minute. The speed can be said to be very fast.
Another highlight is the 320MHz bandwidth performance of the 6GHz band. Google phones currently do not support Wi-Fi 7 so it cannot be measured. However, the Lenovo Notebook exceeds the speed of 3G in terms of upload and download speeds. This performance is already far better than Wi-Fi. Fi 6 speed.
At present, we are sharing this data with you first. In the future, we will continue to actually test the data for other Wi-Fi 7 products and share it with you.
