* Extra key which the RIL can use to indicate the radio technology used for a call.
* Valid values are:
* {@link android.telephony.ServiceState#RIL_RADIO_TECHNOLOGY_LTE},
* {@link android.telephony.ServiceState#RIL_RADIO_TECHNOLOGY_IWLAN}, and the other defined
* {@code RIL_RADIO_TECHNOLOGY_*} constants.
* Note: Despite the fact the {@link android.telephony.ServiceState} values are integer
* constants, the values passed for the {@link #EXTRA_CALL_RAT_TYPE} should be strings (e.g.
* "14" vs (int) 14).
* Note: This is used by {@link com.android.internal.telephony.imsphone.ImsPhoneConnection#
* updateWifiStateFromExtras(Bundle)} to determine whether to set the
* {@link android.telecom.Connection#CAPABILITY_WIFI} capability on a connection.
