The main reason is that there are too many wireless devices in the 2.4 GHz band. Although there are about 11 channels in the 2.4 GHz band, with the popularity of various IT devices, such as iPad, mobile phone, PC, game console and so on, the throughput value of multiple devices decreases seriously when they are used at the same time. Secondly, the microwave oven, Bluetooth and wireless mouse also use 2.4 GHz band, which will interfere with other connecting devices.
Since the original road is too congested, a new road will be built to solve the congestion problem, which is the main reason for the appearance of 5GHz band. However, there are not many devices working in the 5GHz band, and the 5GHz channel is several times more than the 2.4 GHz channel, so it can solve the congestion problem well. In addition, 5g router has the advantages of fast transmission speed and good anti-interference.
Shortcomings of 5g router
Firstly, the wireless router supports 5GHz, but your mobile phone and tablet do not necessarily support 5GHz band connection. The second is that the penetration is slightly poor, the higher the frequency, the worse the penetration, and the wall penetration capacity is 2.4 GHz worse than the same period of last year. Replacing the antenna can solve the problem. In addition, it should be emphasized that the current dual-band routers mostly support 2.4 GHz and 5 GHz at the same time, so even if your device does not support 5 GHz or 5 GHz signal is not good, it can still connect to 2.4 GHz band.
