Depends on your local laws. And on the content of the trace as well probably.

If there is only broadcast info, I don't think that's a problem. If
OTOH there is some cleartext traffic then it probably violates some
privacy intrusion law. And if it's not private but law enforcement,
then other laws probably supercedes the 'normal' case ...

(IANAL,statements based on my understanding of Belgian law which may
not be applicable)

Did you miss the part about the algorithm being secret and never leaked ?

We have no idea what TEA{1,2,3,4} are so there is no public analysis of them ...
