How to Use wifi-linux to detect AP signal strength
As a Python geek, I like to explore new Python tools for Linux users on github. Today I found a tool written in Python for detecting AP signal strength: wifi-linux.
I have been ex

Get the currently connected WiFi informationWifimanager Wifi_service = (wifimanager) getsystemservice (Wifi_service);Wifiinfo wifiinfo = Wifi_service.getconnectioninfo ();Where Wifiinfo has the following methods:Wifiinfo.getbssid ();Wifiinfo.getssid ();Wifiinfo.getipaddress (); Gets the IP address.Wifiinfo.getmacaddress (); Gets the MAC address.Wifiinfo.getnetworkid (); Gets the network ID.Wifiinfo.getlinkspeed (); Gets the connection speed, which
This article illustrates how Android gets the strength of the currently connected WiFi signal, and is a very common and important skill in Android development. Share for everyone to use for reference. The specific methods are as follows:

WiFi Wi-Fi has become almost an essential element in modern life, and your smartphone, tablet, computer and even TV all need to surf the web. When it comes to improving the "speed", basically need to consider from two aspects, one is to promote broadband bandwidth, the second is to strengthen wireless signal. Because wireless signals are generated by a wireless router, and the routers are different because

Although the various APIs that directly get signal strength are blocked. But there is another kind of black magic that can be acquired. That's traversing the uistatusbar.- (void) getsignalstrength{uiapplication*app =[UIApplication sharedapplication]; Nsarray*subviews = [[[App Valueforkey:@"StatusBar"] Valueforkey:@"Foregroundview"] subviews]; NSString*datanetworkitemview =Nil; for(IDSubviewinchsubviews) {

a ratio based on 1mW power), calculated as: 10log (Power value/1MW).
[Example] if the power p is 1MW, the converted to dbm is 0dBm.
[For example] for 0.01mW power, the value in dbm unit should be: 10log (0.01/1) =-20dbm.
The larger the value, the better the signal. Because the cell phone signal strength is generally small, converted into dbm is generally nega

Firmware updates for the iOS system often include fixes for bugs, errors, and sometimes enhancements to the network segment. If you have a bad WiFi
The UI Signal display on the android interface is implemented by sending AT commands to the communication module through RIL. For example, at + CSQ, we can obtain real-time RIL information through logcat-B radio.
So how long does the signal display refresh on the interface?

Before modifying the displayed signal strength, let's take a look at what is dB and what is dBm?
1. dBDB is a value that represents relative
In wireless coverage engineering, it is often necessary to test the wireless signal strength of the field to determine if the wireless signal is in place and whether the wireless signal strength meets the requirements. Wireless WiFi

When one DBM is used to subtract another dBm, the result is dB, for example, 30dbm-0dbm = 30db.
