How about a small WiFi signal？

How about a small WiFi signal?

　　Because the small WiFi device is very small and does not have a strengthened "extension antenna", many friends are worried about its signal strength and penetration. The actual test barrier-free distance is about 10 meters or separated by 2 walls and 1 glass. It can still be used, but the signal is already relatively weak, so the distance between the walls of the general house and the upstairs and downstairs should not be a problem.

Small WiFi signal test experience

　　According to the official introduction, Xiaodu WiFi uses the latest 55nm MT7601 chip, which conforms to the IEEE 802.11n protocol, is compatible with IEEE 802.11g and IEEE 802.11b standards, and supports 2.4 frequency bands. This is also the latest wireless module launched this year. It is better than the 99nm RT5370 core that congeneric products commonly used two years ago. As users, we don’t need to know too much about these parameters.

　　First of all, we still use some professional testing tools, Speed Test, mainly for uploading and downloading tests; WiFi Overview 360 wireless network analysis software, mainly for wireless signal testing. Then I will tell you my actual experience.

　　The figure below is the network speed test of Xiaodu WiFi, and the figure below is the wireless router speed result of our office environment, which varies greatly, right? The main reason is that my mobile phone is next to Xiaodu WiFi, while the wireless router in the office is far away from me, and there are many connections, so these parameters are for reference only.

　　In the test of WiFi signal, the mobile phone terminal is close to the computer, and the small WiFi is almost full. As the distance increases, it keeps changing, reducing by half when it is about 5 meters, relatively weak when it is 10 meters, and disconnected when it is 15 meters.

　　Numbers cannot explain everything, especially the different network usage environments, but the use of small WiFi products is generally not very far away, such as bedrooms, small-scale office environments, or friends around the airport waiting, so the WiFi connection speed will not be very poor, and in the afternoon test, small WiFi performance is very stable, the space distance can be used within about 15 meters, the effect of the partition wall, if there is a door, that is, the signal has a space to pass through, it is basically fine, if the interval of the enclosed space, let alone this small WiFi, even the home router is not very good. The wireless router in the company is still enterprise-grade, and we have no signal in some spaces.
