how to get EC/IO and GsmBitErrorRate for GSM value in android?

On Android, how do I get the GSM network's EC/IO and BitErrorRate values?

I am using the API:

signalStrength.getCdmaEcio();
signalStrength.getEvdoEcio();
signalStrength.getGsmBitErrorRate();

But all of these return -1 value.

Please, any suggesti开发者_如何学Goons?

I'm facing the same problem as you, and I've been searching information, and I found out that GSM and CDMA are different technologies, EVDO works over CDMA, so if you are using a UMTS (GSM) SIM card the signalStrength.getCdmaEcio(); signalStrength.getEvdoEcio() will return -1, because you are working with a different technology.
I'm a little confused about the BER measure too. Anyway, I hope this helps you. If I find out the way I'll let you know.
