terminal is 1 m (hips/belly).

vertical. When the mobile terminal is a laptop computer, the screen is
vertical, and the computer is set up so that the display side of the
screen is in direction of the wall opposite to the point where the
mobile is located (when appliable).
** Measurement procedure
- The infrastructure (Listeners and Aggregator) must be started first
and at least a round of autocalibration request done (i.e. each
capture point must have sent at least one autocalibration request)
before the mobile terminal is started.
- In the scenario in which a human has to move along a path, a metronome
is set up with the tempo at which the person has to walk. For example,
60 bpm if the pace is of one metre per second.

This scenario uses measurement points 1 and 5-10. For each measurement

The room divider is half-closed (from the East wall to the center of the

This scenario aims to evaluate the impact of horizontal capture points'
antennas. The scenario 1 is repeated partially (for the measurement
points 3, 4 and 5 only) two times:
1. Each capture point antenna is disposed horizontally, pointing in the
direction of the opposite wall.
