Huawei and Xiaomi, the box has a strong WIFI receiving capability

The main function of the TV box product is the video playback function. Corresponding users want to watch TV cool, you need to have a powerful WIFI receiving capability, escort the user! Which TV box WIFI ability? Xiao Bian compares Huawei's box M330 and millet box 1G enhanced version, which are the most concerned about at the moment, to learn more about the WIFI receiving capabilities of the two TV boxes and to help users understand the details before buying!



Environmental description:

Router 2x2 wireless router, router in the living room on the second floor.

Test point A (second floor living room) B (second floor bedroom) C (second floor bedroom) D (first floor living room).



Test environment

The test results are as follows:



Huawei Box M330 and Millet Box 1G Enhanced Comparison Test Data

In addition, give everyone a look at the basic situation of 5G AC in the world: Global routers, AC ratio is less than 10%, China is less than 5%. Therefore, for more than 95% of users, Xiaomi's AC is a gimmick and has no practical significance. Huawei Box has spent 95% of its users (the other 5% can also meet).

By the way, talk about the network port, millet box 1G enhanced version does not have a network port, and Huawei Box M330 has retained the Ethernet interface, for users who do not have a wireless router / or interfere with the home, this is simply "life-saving straw."



Interface comparison

to sum up:
From the above test data, it can be seen that in the same environment, Huawei's box M330 receive/send rate is significantly better than the 1G enhanced version of the millet box. In particular, the millet box 5G AC performed very poorly in the case of wearing 2 walls, far less than the Huawei box. The “Huawei Patented Block Antenna” and “Huawei Patented Resonant Isolation Unit” used by Huawei boxes in wireless transmission are not really blowing. In addition, Huawei's box also comes with a network port, Wi-Fi + dual cable protection, let you see even more cool.

Recommendation: How good is Huawei and PPBOX?

Control impedance PCB
Many customers asked us what information we need for impedence control PCB.Here,there are two types for PCB manufacturer,a is single impedance ,just one trace ,two holes .and b is differential impedance,it always go with 1 pair (two trace with same width and space). For single impedance,you just tell us the trace width one which layer and what value you require .For differential impedance,trace width/space,layers and value. Our experience engineers will calculate following your instruction with Polar software.We may change trace width/space or stackup ,but please do not worry, if any changes,we will send you to approve before proceeding. Generally,the tolerance is 10%,and more accurate is 8% .All impedance boards ,we will test here and report.
