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.
Thanks for your response. I had not considered the ability to derive C1 by looking for unencrypted traffic.
So, just to clarify, am I correct that every single 'A' metric and also K1 and T1 are easy to derive from airprobe and wireshark ?
What about T1 (registration timer) ?
