After starting the iPhone 12, the user found a new function.
In short, after turning on the personal hotspot feature on the iPhone 12,Will default to 5 GHz band Wi-Fi signal distribution, you know that the previous iPhone is only 2.4 GHz .5。
Of course, Apple also offers an option to maximize compatibility, which will switch back to the 2.4GHz band when it is turned on, but officials also indicate that this may slow down the network speed.
Wi Fi signal operating in 5GHz band has larger peak bandwidth and smaller interference, but its disadvantage is that the transmission distance and coverage are far less than 2.4GHz, which is determined by wavelength diffraction.
In most cases, the machine connecting the hot spot is close to the machine leaving the hot spot. 5GHz can be said to be very useful.
In addition, after iPhone 12 supports 5g network, the network speed of the machine is greatly increased, which also lays a solid foundation for hotspot sharing.
Unfortunately, there is no 2.4GHz hotspot yet. Compared with the measured network speed of 5GHz hotspot, it is not clear how much difference the signal and network speed will be after iPhone 12 is turned on.
