// Import Platform Service Interface
import com.nokia.lib.Service;
// Heading of the application
heading_txt.text = "Checking Network Strength";
// Create new Service object which has SystemInfo Service data
var sysInfo = new Service("Service.SysInfo", "ISysInfo");
// Define input parameters
var inParams = {Entity:"Network", Key:"SignalStrength"};
// Retrieve information about a system attribute with an asynchronous call
// Define callback function
function onReceive(transactionID:Number, eventID:String, outParam:Object) {
if (outParam.ErrorCode == 0) {
var systemData = outParam.ReturnValue;
var signalStrength = systemData.Status;
// Signal Strength is between 40 - 110 dB, where 40 is high
text_txt.text = "Network Strength: "+signalStrength+"dB";
} else {
var errorId = outParam.ErrorCode;
text_txt.text = "Error: "+errorId;


Network signal strength of the device is displayed. The signal of the strength is between 40-110 dB, where 40 is high.

Example application

The following sample application has been tested in the Nokia 5800 XpressMusic (S60 5th edition, Flash Lite 3.0): File:FlashLite Checking Network Strength.zip
