5G wireless WiFi refers to the fifth-generation wireless WiFi transmission technology, and operates in the 5Ghz radio wave band (the G here is not the 3G or 4G network we are talking about in the wide area network).
1. 5G wifi range
According to relevant data, the coverage radius of the operator's 2G wifi range is about 5 to 10 kilometers, the coverage radius of the 3G wifi range is about 2 to 5 kilometers, the coverage radius of the 4G wifi range is about 1 to 3 kilometers, and the coverage radius of the 5G wifi range is about 100 to 300 meters. Through data comparison, you can clearly find such a problem, the distance covered by the communication network becomes shorter and shorter after the upgrade.
2. 5Ghz wifi range: 4900 - 5900 hz
3. 5Ghz wifi router range
The 5G frequency band setting in WiFi can be determined according to the usage range of the user.
If the WiFi needs to cover a wider range and there is a wall in the range, it can be set to 20MHz; on the contrary, if the WiFi needs to cover a smaller range and a stable transmission rate is required, it can be set to 40MHz or 80MHz.
Users can choose the corresponding frequency band according to actual needs. If they want good penetration and long distance, they can choose 20MHz corresponding to 65M bandwidth, but the speed is relatively slow;
If you want fast speed, you can choose 40MHz corresponding to 150M bandwidth, which has poor penetration and short transmission distance (about 50 meters), while 80MHz corresponds to 300M bandwidth, with the worst penetration and the closest distance (about 20 meters) But the fastest.
3.1 Extended information
20MHZ is a single channel, 40MHZ is a dual channel, the current common router single channel is up to 150M, and the dual channel can reach 300M.
Wireless routing work is divided into several standards according to different frequency bands, namely 11a, 11b, 11g, and 11n. Among them, different working frequency bands also lead to different transmission speeds. 11n can be used in both 11b and 11g, automatic conversion.
Band bandwidth refers to the width of the transmission frequency of the router:
20MHz corresponds to 65M bandwidth, with good penetration and long transmission distance (about 100 meters). 40MHz corresponds to 150M bandwidth, with poor penetration and short transmission distance (about 50 meters). 80MHZ corresponds to 300M bandwidth, with the worst penetration and the closest distance (about 20 meters).
