WIFI Advantages

WIFI is a wireless networking technology, we connected to a computer via network cable previously, but now it is through radio waves to connect internet; common situation is a wireless router, then in the effective range of radio coverage of the wireless router the WIFI connection can be used to interconnect, if the wireless router connected to an ADSL line, or other device access to the Internet, the wireless router is also known as "hot spots."
The common speed of wireless router now mostly 54M in the market, and then the higher level is the speed of 108M, of course, this speed is not the Internet speed, Internet speed depends mainly on the WIFI hot point internet line.

WIFI outstanding advantages
First, the radio waves have a wide range coverage, radio coverage based on Bluetooth technology is very small, only about 50 feet radius, about 15 meters, while the Wi-Fi is up to 300 feet radius, about 100 meters around, Needless to say the office, it can also be used in the whole building. A new switch launched by the Vivato recently, it is learned that this products can extend the current WIFI communication distance which close to 300 feet to 4 miles (about 6.5 km).

Second, although the wireless communication transmission quality under Wi-Fi technology, is not very good, data security performance worse than the Bluetooth，transmission quality also needs to be improved, but the transfer speed is very fast and can reach 54mbps, in line with personal and social information needs.

Third, the threshold firms entering the field is relatively low. Manufacturers only need to set up "hot spots" in the airport, railway stations, coffee shops, libraries and other densely populated place, and connect internet by high-speed access lines. In this way, because "Hot point" radio waves emitted from the access point can reach a radius of few tens of meters to 100 meters, the user in the region with notebook computer or WIFI mobile phone support the wireless LAN can high-speed access internet. In other words, Manufacturers do not have to spend money to carry on the network cabling, thus saving a lot of costs

No wiring
The main advantage of WiFi is does not require wiring, can be exempted from wiring constraints, so it is very suitable for the needs of mobile users, and has broad market prospects. Currently, it has been open up to to more other special sectors industries from the traditional health care, inventory control and management services, and even begun to enter the family, as well as educational institutions and other fields.

Health and Safety
IEEE802.11 required transmit power can not exceed 100 mW, the actual transmission power is about 60 ~ 70 mW, what this mean? Phone transmission power is about 200 milliwatts to 1 watt, the hand-held walkie-talkie up to 5 watts, and wireless networks is not direct contact with the human body like mobile phone, is absolutely safe.
