What is wifi??? What do you need to turn on wifi? 5

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 wireless internet. The common one is a wireless router, then the effective range of the radio wave coverage of this wireless router can be connected to the Internet by wifi connection, if the wireless router is connected to an ADSL line or other Internet lines, it is also called a "hot spot".

Most of the common wireless routers on the market today have a speed of 150M, and Wi-Fi routers with a speed of 300M are gradually becoming more common. The next generation of Wi-Fi standards has been developed and launched, and the maximum transmission rate is achievable. Of course, this speed is not the speed of the Internet, and the speed of the Internet mainly depends on the Internet line of the wifi hotspot.

WiFi is the meaning of wireless LAN, and you need to support software and hardware facilities to open WiFi.

Even if you don't need money, you can also access the Internet wirelessly, just like a laptop, if someone nearby uses a wireless network card to access the Internet, and there is no password, you can also follow. As long as you have a network cable network card, you can turn on wifi

It is necessary to turn on the ofdma function.

There are two advanced settings for WiFi in the TP-Link router, of which wireless WiFi has two advanced options of TWT and OFDMA, and 5GWIFI has three options of TWT, MU-MIMO and OFDMA.

Note. The OFDMA multiple access system divides the transmission bandwidth into a series of orthogonal and non-overlapping subcarrier sets, and assigns different subcarrier sets to different users to achieve multiple access.

The OFDMA system can dynamically allocate the available bandwidth resources to the users who need them, and it is easy to realize the optimal utilization of system resources. Since different users occupy non-overlapping subcarrier sets, the system is free of multi-household interference, i.e., no multiple access interference (MAI) under ideal synchronization conditions.

Compared with 3G modulation schemes such as CDMA (Code Division Multiple Access Access) wideband CDMA and Universal Mobile Communications System (UMTS), it has the advantage of higher spectral efficiency and better anti-fading performance. For users with low data rates, it only requires lower transmit power consumption, shorter latency with constant rather than time-varying latency, and a more concise way to avoid collisions.

1. Enter the default management address of the wireless router in the computer browser. Then enter the administrative password and click Confirm.

2. In this way, you can enter the router management settings interface. Click on the network parameters, select the WAN port setting in the pop-up options, and enter the broadband account and password.

3. Enter the broadband account and password in the interface on the right, so that you can use WiFi.

4. Select the wireless setting option.

5. Then you can set the wifi password, which can prevent others from rubbing the network. Then when connecting to the wifi, enter the wifi password you set to connect successfully.

First of all, you don't have a computer at home, if there is, it's very easy to go online or buy a wireless router in a computer store, generally a hundred or so yuan, the store is about more than a hundred, the brand of Pulian is good, and then follow the instructions to connect the wire, and then set up a broadband account and password to restart the router can go online, the router and other connected cats are equal to a transmitter, and the mobile phone or notebook that supports wifi has a built-in wifi module is equal to a receiver, When you set up, it's best to set a password so as not to prevent others from sharing your broadband and slow down the network speed, how to wiring and setting instructions are written, if you don't have a computer and broadband at home, then there is no way, unless you turn on wireless Internet access on your mobile phone, but that is very expensive and not cost-effective.

You just need to get a wireless router, just like a laptop connected to wireless.

If you have wireless internet access at home.

When you have a wifi signal, you can access the Internet without going through the network of China Mobile Unicom, saving traffic fees.

Outside the race, similar to the infinite router, someone turns on the router and you can connect to the Internet with a mobile phone or laptop,
