Regular WiFi connectivity means there is one channel for uploading and another channel for downloading. But when it’s called 2×2, it means we are dealing with a dual-channel for uploading as well as another dual-channel for downloading. Shortly, it’s the same as a two-way two-lane highway. Therefore, the data transfer can be implemented slightly faster. Other than that, the Xiaomi Mi 6 supports the latest 802.11ac standard. There are 4 external antennas supporting MU-MIMO technology. Finally, the phone supports “beamforming” technology on these top wireless routers 2017.
To understand what it means, we tested the Xiaomi Mi 6’s WiFi connectivity. The WiFi router was fixed in the middle of a room. As you can see from the photo below, it provides bad signal at certain places of the building. First, the phone was tested from 1st to 5th positions with dual-antenna options enabled. As you can see, the best results are shown on 3rd and 5th positions.
The same test was implemented with a single-antenna enabled. As you see, the results are identical. Only the 1st positions’ results differ from each other.
When it comes to comparing signal and network stability, it becomes clear why this phone comes with such a technology. Obviously, the dual-channel WiFi test showcases better results than the single channel test.
So what we can conclude. The comparison chart above shows dual-channel dual-way WiFi connectivity provides stronger signal as well as a stable network connection. As for a regular users, this means they can use the Xiaomi Mi 6 in any corner of their houses without worrying about the WiFi signal strength and stability.
P.S. Though these results can be achieved due to 2×2 WiFi technology, the housing Xiaomi’s current flagship is made of affects the results as well.
