An SDR can, in theory, capture more information that is just available
to the phone and can do so passively. Many of the same metrics apply
but can be derived from other traffic, e.g., for C1 the presence of
any unencrypted traffic on any channel in countries where traffic is
normally encrypted is a big giveaway.  Passively monitoring traffic
gives a more complete picture. It is, however, a game that a much
smaller number of participants can play because the hardware
requirements are for a suitable SDR rather than just a
Qualcomm-equiped Android phone.
