What is the wifi transmission distance?

WiFi transmission distance: 1. The transmission distance of commercial equipment is generally about 300 meters; 2. The transmission distance of home equipment is generally about 10~50 meters; 3. The transmission distance of small mini equipment is 5 meters about.

Wi-Fi (Wireless-Fidelity) is a system that can connect personal computers, handheld devices (such as PDAs, mobile phones) and other terminals to each other wirelessly technology.
