Hi,
Different areas every day… Mobile RF jammer ?? It happens in some countries… where the king goes, the jammer goes.
The RA ref can be found in the channel request (Air) or the channel required (Abis).
How can you trace the Air (Um) interface for all users ? Do you know such a tool ?
In my mind, the trace i ask you is on the abis. The Air is IMO impossible to trace (but am i wrong ?)
