How do you look at wifi analysis, it means you don t understand it

Go back to the memory of a short time ago.

How to use the wifi analyzer:

2. It can be used to search for nearby WiFi signals. This view lists the SSID, MAC, channel, encryption method, and signal strength of nearby wireless hotspots in a list. The strength of the signal is expressed in dBm, with a higher number (-50 is greater than -80 because it is negative) indicating a stronger signal.

A WiFi analyzer can show surrounding Wi-Fi channel usage, helping wireless routing to select a relatively idle channel to improve connection quality.

The permissions required for the WiFi analyzer include: opening the network interface, accessing information on the network, accessing information about the Wi-Fi network, changing the connection status of the Wi-Fi, power lock management, and writing to the user's external memory;

The systems supported by WiFi Analyzer include: Android.

Wi-Fi is commonly known as wireless broadband, which does not require a network cable, but there must be a hotspot nearby, some with a password, and some without.

What you're asking is why some wifi charges money and some are free, well, let's say so, let you not be on, free or not is determined by the router side that provides wifi hotspots. There are some free WiFi hotspots, such as those sent out through their own routers at home, in the library, in hotels, etc. There are also some that you said about charging money or ** included, for example, China Telecom, Mobile, Unicom wifi hotspots.

As for students who want the school to have a free WiFi hotspot, they need the school to set up a LAN wireless routing hotspot.

Isn't 3G internet cheap now? Let's wrap it up.

Wifi is made by a communication company, for example, our school is the wifi of Telecom, and our school's network is a network of Telecom, 48 blocks per month, 240 hours, and then 10 hours of wifi time. These 10 hours are the 10 hours that we can use with mobile phones, computers, tablets and other devices that can be connected to wifi. As you said, if you can use your mobile phone, you can also use your computer.

It will not be charged for mobile phones and computers, and the communication company will not give you free access to wifi, which you have to understand, after all, it costs money to install wifi equipment. There is also the fact that wifi can only be used in areas that are covered, and areas that are not covered cannot be used.
