For example, to obtain call detail records from a cellular carrier, you will need to specify exactly what you want to get in the subpoena response. In a case involv- ing cell tower locations for a cellular phone, just getting the call detail records is not enough to properly perform an analysis. You will also need to have language in your subpoena to obtain engineering and maintenance information about the cell towers of interest.
