5gwifi bandwidth choose 40 or 80

5gwifi bandwidth selection of 40 or 80 depends on the situation; the 5G frequency band setting in wifi can be determined according to the user's usage range. If the wifi needs a smaller coverage area and a stable transmission rate, you can Set to 40MHz; if you want fast speed, you can choose 80MHz, but 80MHz has poor penetration and short transmission distance.

Which 5gwifi bandwidth should be 40 or 80?

Subject to availability. The 5G frequency band settings in WiFi can be determined according to the user's usage range. If WiFi needs a smaller coverage area and a stable transmission rate, it can be set to 40MHz. If you want fast speed, you can choose 80MHz, but 80MHz has poor penetration and short transmission distance.

The fifth generation mobile communication technology (5G) is a new generation of broadband mobile communication technology with the characteristics of high speed, low delay and large connection , 5G communication facilities are network infrastructure that realizes the interconnection of humans, machines, and things.

The International Telecommunications Union (ITU) has defined three major application scenarios for 5G, namely enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (uRLLC) and massive machine type communications (mMTC). Enhanced mobile broadband (eMBB) is mainly aimed at the explosive growth of mobile Internet traffic and provides mobile Internet users with a more extreme application experience; ultra-high reliability and low latency communication (uRLLC) is mainly aimed at industrial control, telemedicine, autonomous driving, etc. and vertical industry application needs with extremely high requirements on reliability; Massive Machine Type Communications (mMTC) is mainly oriented to application needs targeting sensing and data collection such as smart cities, smart homes, and environmental monitoring.

In order to meet the diverse application scenarios of 5G, the key performance indicators of 5G are more diversified. ITU has defined eight key performance indicators of 5G. Among them, high speed, low latency, and large connections have become the most prominent features of 5G. The user experience rate reaches 1Gbps, the latency is as low as 1ms, and the user connection capability reaches 1 million connections/square kilometer.
