The client terminal is located at MP12 (10 m north of the position of
t01), a few metres south of the north-west/north-east bifurcation.
Therefore, it is at 11.60 m from the south wall. It is not in line of
sight with CP1 any more.
Coordinates: 155.50;168.50;0.70

The +coord file has been cleared from the first positioning requests so
that two rounds of autocalibration are done before the first request
from the mobile.
