I am trying to puzzle out the distinction between the hazards associated with CDMA and GSM signals.  These almost entirely describe how the data is encoded, before radio transmission.  The   hazard (assuming it exists) can only be a function of the radio signal energy and the frequency band in use.  It seems inconceivable that the way the data is encoded on the RF carrier can have any influence on the outcome.  That would be almost at the level of blaming the results on the topic that was being discussed in the conversation on the cellphone.
