1, wifi is included in the wireless local area network, and the coverage range is different with different power of the transmitted signal. In fact, WIFI is the trademark of WLANA (Wireless Local Area Network Alliance). This trademark only guarantees that the goods using this trademark can cooperate with each other, and has nothing to do with the standard itself. However, because WIFI mainly adopts the 802. 1 1b protocol, people gradually get used to calling it 802.6438.808086, which is a standard of WlAN and included in WlAN, and belongs to a new technology adopting WLAN protocol. The coverage of WiFi can reach about 300 feet (about 90 meters), and the maximum WLAN (plus antenna) can reach 5 kilometers.
2. Covered wireless signal range is different from WIFI(WirelessFidelity), which is also called 802. 1 1b standard. Its biggest advantage is its fast transmission speed, which can reach 1 1Mbps. In addition, its effective distance is very long, which is also different from the existing 802. 165438+. Wireless Internet access has become a reality.
Radio waves cover a wide area. The coverage 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, the coverage of wifi signals will be wider in the future.
