The coverage range of wifi can reach about 90 meters, and the maximum wireless LAN can reach 5KM. WiFi is a standard for wireless LAN. WiFi is included in wireless LAN and is a new technology using wireless LAN protocol.
1. WiFi is included in wireless LAN. The power of the transmitted signal is different and the coverage is different. In fact, WIFI is a trademark of WLANA (Wireless LAN Alliance). This trademark only guarantees that products using this trademark can communicate with each other. It has nothing to do with the standard itself, but 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 using 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. In addition, its effective distance is also very long. It is also 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 (15 meters), while the radius of Wi-Fi can reach about 300 feet (90 meters). rice. However, with the development of wifi technology, wifi signals will cover a wider range in the future.
