How to show GPS strength signal in tizen / xamarin wearable app?

Question

Can someone help me how to simply show GSM strength signal? I am using TIZEN and XAMARIN in .NET C#

I found this on google, but it is not working, without any error

    `private Network network;

    public Network GetNetwork()
    {
        return network;
    }

    public void getGSMstrength()
    {

            var sila = GetNetwork();
            gsm.Text = sila.CurrentRssi.ToString();

    }`
