What exactly is wifi? What is WIFI?

1. WiFi is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones).

2. Wifi technology, like Bluetooth technology, belongs to the short-range wireless technology used in the office and home.

Wireless Internet access tools.

Wi-Fi, also known as "mobile hotspot" in Chinese, is a Wi-Fi Alliance manufacturer's trademark as a brand certification of products, and is a wireless LAN technology created in standards. Due to the close relationship between the two systems, Wi-Fi is often used as a synonym for IEEE standards. "Wi-Fi" is often written as "WiFi" or "WiFi", but they are not recognized by the Wi-Fi Alliance.

Not every product that matches the IEEE applies for Wi-Fi Alliance certification, and a product that lacks Wi-Fi certification does not necessarily mean that it is not compatible with Wi-Fi devices.

IEEE devices are installed in many products on the market, such as personal computers, game consoles, *****, smartphones, tablets, printers, laptops, and other peripherals that can be used to access the Internet wirelessly.

WiFi is a kind of wireless networking technology (commonly known as: wireless broadband), and now mobile terminals (laptops, tablets, smart phones, MP4) can basically receive WiFi signals, and access to WiFi is completely free.

Specifically, WiFi is a technology that allows electronic devices to connect to a wireless local area network (WLAN).

Wi-Fi is a short-range wireless transmission technology, a wireless networking protocol that is capable of supporting Internet access over radio signals over a range of hundreds of feet, which provides users with wireless broadband Internet access. The above information is for reference only, Guangxi Telecom worry-free card, monthly rent is only five yuan, traffic ladder billing, the more you use, the cheaper, the details can be logged in to Guangxi Telecom online business hall for inquiries, customer service 28 for you to answer.

Wi-Fi, like Bluetooth, is a short-range wireless technology used in the office and at home.

Today's mobile phones, tablets, and notebooks are equipped with WiFi function modules as standard, and can be connected to Wi-Fi heat sources through built-in Wi-F modules, WiFi heat sources are generally wireless routers, and wireless routers are generally connected to broadband, so devices with WiFi function are connected to broadband like computers, and you can surf the Internet at high speed.

There are two conditions for using Wi-F: 1There are wireless access points nearby that can be accessed, such as wireless routers at home, free heat sources in public places; 2. The device has wifi function, that is, the hardware has wifi function module.

To put it simply, it's a wireless propagation technology that's fast, and it's all available in smartphones today.

Wi-Fi is a technology that allows terminals such as PCs and handheld devices (such as PDAs and mobile phones) to be wirelessly connected to each other. Wi-Fi is a brand of wireless network communication technology owned by the Wi-Fi Alliance. The aim is to improve interoperability between wireless network products based on IEEE standards.

Nowadays, most people confuse Wi-Fi and IEEE. Even equate Wi-Fi with the wireless Internet.

WiFi is a type of wireless network access technology, just like Starbucks, Texley wireless routers. Nowadays, many people have it in their homes. A router acts as a bridge that connects computers together and uses a modem to connect the router to the Internet.

That's why there's a wireless network. (But not all wifi has an internet connection, some just act as a LAN bridge instead of expensive servers, that is, intranets, just computers are connected to computers, not to the Internet).

It's a synonym for WLAN.

Wi-Fi is what we often call wireless broadband.

In fact, it converts the wired network signal into a wireless signal for the relevant computers, mobile phones, PDAs, etc. that support its technology. If the mobile phone has a wifi function, when there is a wifi wireless signal, you can access the Internet without going through the network of China Mobile Unicom, saving the traffic fee. But the wifi signal is also provided by the wired network, such as the ADSL at home, community broadband, etc., as long as you connect a wireless router, you can convert the wired signal into a WiFi signal.

Many cities in developed countries abroad are covered with wifi signals provided by ** or large companies for residents to use.

Compared with 3G Internet access, the latter 2G Internet access is generally speaking, most of the WiFi is fast, power-saving, no traffic limit, wireless devices do not need to insert SIM cards, that is to say, there is no need to take SIM card traffic.

Wi-Fi, you can wirelessly connect mobile phones and laptops to the Internet at very fast speeds.

A wireless signal emitted by the router.

WiFi is to connect the mobile phone to the computer through the wifi router to the broadband of the computer is to enjoy broadband with the computer. Your phone will be able to access the Internet wirelessly.

There are a lot of explanations in this question, why do you want to ask such a question?

As for the specific situation asked in this question, it is really not clear. If you add more details to the problem, **clearer, maybe some netizens can help you.

Wi-Fi is also known as wireless network, called mobile hotspot in Chinese, is the trademark of the Wi-Fi Alliance manufacturer as the brand certification of the product, is a wireless LAN technology created in the IEEE standard.
