Wi-Fi is a technology that can connect terminals such as personal computers, handheld devices (such as PDAs, mobile phones) to each other wirelessly.
Wi-Fi is a brand of wireless network communication technology, owned by the Wi-Fi Alliance. The purpose is to improve interoperability between wireless network products based on the IEEE 802.11 standard.
Now, most people will confuse Wi-Fi and IEEE 802.11. Wi-Fi is even equated with wireless Internet.
Wi-Fi Alliance was founded in 1999 and was named Wireless Ethernet Compatibility Alliance (WECA). In October 2002, it was officially renamed Wi-Fi Alliance.
Precisely speaking:
WIFI is a wireless networking technology. It used to connect to computers through network cables, but now it is connected to the network through radio waves; the common one is a wireless router, so the effective range of radio wave coverage of this wireless router can be connected to the network using WIFI connection. If the wireless router is connected to an ADSL line or other Internet access line, it is also called &ldquo: "Hotspot &rdquo".
The common wireless routers on the market nowadays are mostly 54M speeds, and the next level is 108M speeds. Of course, this speed is not the speed you are on the Internet. The speeds you are on the Internet mainly depend on the Internet lines of the WIFI hotspot.
Convert the received gprs or 3g signals of the mobile phone into a wifi signal and then send it out. In this way, your mobile phone becomes a wifi hotspot. The mobile phone must have wireless AAP function to be regarded as a hotspot. Now some systems come with hotspots, such as iOS (such as iPhone 4), and those like Le phone need to be expanded by third-party software. Le phone is an Android system. Just install Wifi Tether software and set it up (others are also possible, there are many such software on the Android system).
If you treat your Le phone as a hot spot, then those with wifi functions like touch and pad can search for the wifi network established by your phone. After connecting, the traffic generated by TOUCH and other WIFI consumes the GPRRS or 3G traffic of the mobile phone card in the Le phone, so it is best to put a large network card in the Le phone. Also, it is very power-consuming to treat your phone as a hot spot, and plug in a charger when it is best to use it.
