<p>With the Hot Spot location measurement, the operator finds
out where the majority of the subscribers are located in the cell’s coverage
area. So the places where more capacity is needed can be predicted. The locationing
is based on the timing advances of the three best adjacent cells reported
by the mobiles during the calls. One cell under one BSC can be measured simultaneously.
The BSC fills the appeared triplets of adjacent cells, and the distribution
to different timing advance classes to a table as follows:</p>

<p>The BSC reports ten most frequently appeared triplets,
and the distribution to timing advances to the NetAct after each measurement
interval. The operator gets most out of the results of this measurement with
the post processing tools in the NetAct Planner.</p>
