1. WiFi is included in wireless LAN. The power of the transmitted signal is different and the coverage range is different. In fact, WIFI is a trademark of WL ANA (Wireless LAN Alliance). This trademark only ensures that products using this trademark can communicate with each other. They can cooperate with each other, which actually has nothing to do with the standard itself. However, because WIFI mainly uses the 802.11b protocol, people have gradually become accustomed to using WIF to call the 802.11b protocol.

In terms of inclusion relationship, WIFI is a standard of WLAN. WIFI is included in WLAN and is a new technology that adopts WLAN protocol. The coverage range of WiFi can reach about 300 feet (about 90 meters), and the maximum WLAN (with antenna) can reach 5KM.

2. The covered wireless signal range is different

WIFI (Wireless Fidelity), also known as the 802.11b standard, its biggest advantage is its high transmission speed, which can reach 11Mbps, and its effective distance It is also very long and compatible with various existing 802.11DSSS devices. Wireless Internet access has become a reality.

Radio waves have a wide coverage range. The coverage range of radio waves based on Bluetooth technology is very small, with a diameter of only about 50 feet or 15 meters, while the radius of Wi-Fi can reach about 300 feet or 90 meters. . However, with the development of wifi technology, wifi signals will cover a wider range in the future.
