I'm programming in C# and i want to detect a cell phone(Name, IP address, RSSI, ...) in Wireless Network (Wi-Fi) to calculate after that the distance between my computer and the cell phone
Actually, I'm able to detect computers name connected to the same network with :

```
using System.DirectoryServices;
...

List<String> _ComputerNames = new List<String>();
String _ComputerSchema = "Computer";
DirectoryEntry _WinNTDirectoryEntries = new DirectoryEntry("WinNT:");
foreach (DirectoryEntry _AvailDomains in _WinNTDirectoryEntries.Children)
{
    foreach (DirectoryEntry _PCNameEntry in _AvailDomains.Children)
    {
        if (_PCNameEntry.SchemaClassName.ToLower().Contains(_ComputerSchema.ToLower()))
        {
            _ComputerNames.Add(_PCNameEntry.Name);
        }
    }
}

```

But I cannot find my cell phone that is connect to the same wi-fi network.

How can I resolve this problem ?
Thanks!
