I'm really surprised that packets from home stations outnumber ones from 
mobiles, particularly since home stations (presumably ??) beacon at a 
far lower rate than mobiles, especially mobiles with Smart 
Beaconing.     And surely the ratio of cars to ambulances can't be 
almost 2:1....,.

Any thoughts on these seeming anomalies ?    

[Just discovered that apparently you pasted some sort of table directly 
into email, instead of converting  it to  plain text first.      It is 
rendering with  "Uses" and "Packets" run together, yielding single 
numbers in the millions for each row.]
