Users questions: Such as from the actual talk about what we usually use ah. . What is the difference the agreement would not have said any different use of equipment such as ah: WLAN is a wireless router. . . Etc., and WIFI is. . .
Experts answer:WLAN is WirelessLocalAreaNetwo rk of the acronym refers to wireless communication technology to interconnect computer equipment, which form can communicate with each other and share resources in the network. Wireless LAN feature is not essential to use the computer and network communication cable to connect it through wireless way to connect to the network construction and final More flexible mobile terminal. Wired LAN WLAN communication system as an alternative other than generally used in the same building. WLAN using the ISM (Industrial, Scientific, Medical) radio frequency communication. 80 WLAN 2.11a standard use 5GHz band to support the maximum speed of 54Mbps, while 802.11b and 802.11g standards use the 2.4GHz band, supports up to 11Mbps and 54Mbps respectively, the speed. ================= ==================== Wi-Fi WirelessFidelity, Wi-Fi technology and Bluetooth technologies, belong in the office and home use of short-range wireless technology. The technology used to 2.4GHz frequency band near the It is still useless band wireless spectrum licenses. Its current use of the standard two, respectively, IEEE802.11a and IEEE802.11b. As the technology has its own advantages, so by the manufacturers. WI-FI is dominated by a handful of U.S. companies with information Leverage the strong interest and pointer color, "nonprofit organization", they drew up their own WIFI standard WEP, WPAWi-Fi (wirelessfidelity (wireless fidelity) of the abbreviation) is essentially a commercial certification, with Wi-Fi certified products consistent with IE EE802.11b wireless network standard, which is currently the most widely used WLAN standard, using band is 2.4GHz. IEEE802.11b wireless network standard IEEE802.11 standard is a variant of the maximum bandwidth of 11Mbps, the signal is weak or The case of interference, bandwidth adjustable to 5.5Mbps, 2Mbps and 1Mbps, Automatic bandwidth adjustment, effective protection of the network stability and reliability. Wi-Fi has been identified since the implementation of IEEE802.11b wireless network has made considerable advances in the basic This technology's products gradually over up to address the compatibility issues between manufacturers products is very necessary. Because the IEEE is not responsible for the compatibility test IEEE802.11b wireless products, so the work on their own initiative by the non-profit organization composed of: Wi-Fi alliance Served. The alliance includes the major manufacturers of wireless LAN equipment, such as Intel, Broadcom, and the familiar Chinese manufacturers Asus, BenQ, etc.. Any compatibility testing through the WiFi Alliance's products have been granted marked "Wi-FiCERTIFIE D "mark. Therefore, we choose IEEE802.11b wireless products, the best buy a Wi-Fi tag products to ensure compatibility between products. Wi-Fi (WirelessFidelity, Wireless Fidelity) The official name is "IEEE 802.11b ", and Bluetooth, as belong in the office and home use of short-range wireless technology. While in the data security is concerned, the technology to be worse than Bluetooth, but the radio coverage area will have to slightly better. Wi-Fi coverage is up to about 300 feet (Approximately 90 meters), Office of the self Needless to say, is smaller in the whole building may be used. ========================================= WIFI is a WLAN standard. WLAN maximum (plus antenna) Can go to 5KM ... ... WIFI can not ratio ... ... Attention! IEEE8021B and 8021B are two different standards! ! ! IEEE802.11a standard is a follow-up IEEE802.11b standard, the 802.11b standard is designed to be replaced, however, Working in the 2.4GHz band is not required license, the band is industrial, education, health care and other special band is open, work on the 5.15-8.825GHz band need a license.
