C# - How do I access the WLAN signal strength and others?
提问by TheFlash
Many scientists have published papersdocumenting how devices connected via WLAN can be tracked by measuring its Signal Strength, Time Of Arrival, Round Trip Time, etc. Any idea how I can access these values in Windows using any .NET API?
许多科学家发表了论文，记录了如何通过测量信号强度、到达时间、往返时间等来跟踪通过 WLAN 连接的设备。知道如何使用任何 .NET API 在 Windows 中访问这些值吗？
Or do you know of software SDKs already available for location tracking?
或者您是否知道已经可用于位置跟踪的软件 SDK？

hello for WIndows 7 this is a good code wich can detect all AP with MAC adress RSSI SSID :
你好，对于 WINdows 7，这是一个很好的代码，它可以检测所有具有 MAC 地址 RSSI SSID 的 AP：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using NativeWifi;
class Program
{
static void Main(string[] args)
{
WlanClient client = new WlanClient();
// Wlan = new WlanClient();
try
{
foreach (WlanClient.WlanInterface wlanIface in client.Interfaces)
{
Wlan.WlanBssEntry[] wlanBssEntries = wlanIface.GetNetworkBssList();
foreach (Wlan.WlanBssEntry network in wlanBssEntries)
{
int rss = network.rssi;
// MessageBox.Show(rss.ToString());
byte[] macAddr = network.dot11Bssid;
string tMac = "";
for (int i = 0; i < macAddr.Length; i++)
{
tMac += macAddr[i].ToString("x2").PadLeft(2, '0').ToUpper();
}
Console.WriteLine("Found network with SSID {0}.", System.Text.ASCIIEncoding.ASCII.GetString(network.dot11Ssid.SSID).ToString());
Console.WriteLine("Signal: {0}%.", network.linkQuality);
Console.WriteLine("BSS Type: {0}.", network.dot11BssType);
Console.WriteLine("MAC: {0}.", tMac);
Console.WriteLine("RSSID:{0}", rss.ToString());
}
Console.ReadLine();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
}
i hope it will be helpful enjoy

Windows itself provides a Location APInow.
Windows 本身现在提供了一个位置 API。

The Managed Wifi APIwill provide signal strength information. Here's a code snippet adapted from a question I previously posed and was answered here:
该托管无线上网API将提供信号强度信息。这是改编自我之前提出并在此处回答的问题的代码片段：
static void Main(string[] args)
{
WlanClient client = new WlanClient();
foreach ( WlanClient.WlanInterface wlanIface in client.Interfaces )
{
Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList( 0 );
foreach ( Wlan.WlanAvailableNetwork network in networks )
{
Console.WriteLine( "Found network with SSID {0} and Siqnal Quality {1}.", GetStringForSSID(network.dot11Ssid), network.wlanSignalQuality);
}
}
}
static string GetStringForSSID(Wlan.Dot11Ssid ssid)
{
return Encoding.ASCII.GetString(ssid.SSID, 0, (int) ssid.SSIDLength);
}
