This is a problem that needs to be popular science, worth collecting, can open wifi and hot phones at the same time, must meet a hardware condition, that is, the WiFi antenna of the phone is 2x2, a popular point is dual-way WiFi, and then popular science some related knowledge, hope to be able to solve your worries. Dual WIFI means that there are two WiFi modules, which is equivalent to two wireless card modules built into the mobile phone.
In the traditional 1X1 single-channel WiFi, the receiving and transmitting signals occupy an antenna, which has reached the development bottleneck, so there are some 2X2, 3X3 and even 4X4 multi-channel WiFi devices on the market now, and their WiFi coverage is wider and the transmission rate is faster.
The first mobile phone to use 2x2 dual-channel WiFi is the Xiaomi 6 we are familiar with. To this end, I would like to encourage Xiaomi. The dual-channel WiFi of Xiaomi 6 is to improve the signal reception ability of the mobile phone itself, so as to improve the WiFi signal.
The arrival of dual-way WiFi not only improves the efficiency of mobile phone connection to wifi, but also brings another benefit, that is, the mobile phone with this function can realize the connection to wifi at the same time can also open the mobile phone hotspot, you know that earlier mobile phones can only choose one of the two.
After understanding this knowledge, you can choose a mobile phone according to the requirements, as long as it is a mobile phone with multiple wifi antennas.
Most Android phones can turn on a Bluetooth hotspot after receiving wifi, and other phones can connect to this Bluetooth and have Internet. Like the Mi 5.
