Industrial router wlan and wifi distinction and contact

What is WLAN wireless Internet access?

First of all, we simply introduce the WLAN wireless Internet access, the full name is: Wireless Local Area Networks, Industrial router the Chinese explanation: wireless local area network, is a use of radio frequency (Radio Frequency RF) technology for transmission system, the technology is not used To replace the wired local area network, but to make up for the lack of wired local area network to achieve the purpose of network extension, making wireless LAN can use a simple access architecture allows users through it, to achieve no network, no distance restrictions The internet. WLAN uses ISM (Industrial, Scientific, Medical) radio broadcast band communication. The WLAN 802.11a standard uses the 5 GHz band and supports a maximum speed of 54 Mbps, while the 802.11b and 802.11g standards use the 2.4 GHz band, Industrial router supporting speeds of up to 11 Mbps and 54 Mbps, respectively. At present, the protocol standard of WLAN includes IEEE802.11b protocol, IEEE802.11a protocol, IEEE802.11g protocol, IEEE802.11E protocol, IEEE802.11i protocol and wireless application protocol (WAP).

What is WIFI wireless Internet access?

WIFI (Wireless Fidelity) technology is a IEEE 802.11 series based on the standard wireless network communication technology brand , Which aims to improve the interoperability between wireless network products based on the IEEE 802.11 standard, Industrial router held by the Wi-Fi Alliance (Wi-Fi Alliance), which is simply a wireless networking technology that was previously connected over a network Computer, and now it is through the radio waves to network. The Wi-Fi Alliance (also known as: Wireless Local Area Network Standardization Organization WECA) was established in 1999, when the name is called the Wireless Ethernet Compatibility Alliance (WECA), in October 2002, officially renamed the Wi-Fi Alliance.

And Bluetooth technology, belong to the same office and home in the use of short-range wireless technology. The technology uses a frequency band near 2.4 GHz, which is currently a useless radio band. There are two currently available standards, namely IEEE802.11a and IEEE802.11b. In the case of weak signal or interference, the bandwidth can be adjusted to 5.5Mbps, 2Mbps and 1Mbps, the bandwidth of the automatic adjustment, effective protection of the network stability and reliability. The technology has its own advantages, Industrial router so by the manufacturers of all ages.

wlan and wifi difference one: wifi included in the WLAN, the signal transmission power is different, coverage is different

In fact, WIFI is a trademark of WLANA (Wireless LAN Alliance), which only protects the use of the trademark between the goods can cooperate with each other, and the standard itself is actually no relationship, but because the WIFI mainly use 802.11b protocol, so people gradually accustomed to Use WIFI to call 802.11b protocol. From the inclusion of the relationship, WIFI is a standard WLAN, WIFI included in the WLAN, belonging to the use of WLAN protocol in a new technology. WiFi coverage of up to 300 feet (about 90 meters), Industrial router WLAN maximum (plus antenna) can go to 5KM.

Differences between WIFI and WLAN II: coverage of wireless signal range is different

WIFI (Wireless Fidelity), also known as 802.11b standard, its biggest advantage is the high transmission speed, can reach 11Mbps, while its effective distance is very long, but also with a variety of existing 802.11DSSS equipment compatible. Wireless Internet access has become a reality. Radio waves cover a wide range of Bluetooth-based radio coverage is very small, the radius is only about 50 feet or so about 15 meters, Industrial router while the Wi-Fi radius of up to about 300 feet about 90 meters, the office since Needless to say, It is also available in the whole building. However, with the development of wifi technology, wifi signal coverage of the future will be wider.
