Question: How can I write some code to detect what signal strength is available on a phone?
Answer: You can detect the signal strength using the System Agent API or the RMobillePhone class. Bear in mind however that on real
devices the manufacturer may have a different API that is used and these APIs will not be functional but will return a default
value.
1) RSystemAgent iSystemAgent; User::LeaveIfError(iSystemAgent.Connect()); TInt strength = iSystemAgent.GetState(KUidNetworkStrength);
** Note: the RMobilePhone class is only available for Symbian OS DevKit licensees 2) Until v6.1: RMobilePhone::GetSignalStrength(TInt32& aSignalStrength, TInt8& aBar) From v7.0: MobilePhone::GetSignalStrength(TRequestStatus& aReqStatus, TInt32& aSignalStrength, TInt8& aBar)`
