The data window presents a bar chart showing the number of cells
plotted against the Cell Occupancy average over the selected time
interval. The Cell Occupancy average is the total radio occupancy in
the cell averaged over the total number of radios in that cell. The
specific time interval is indicated above the bar chart. Radio
occupancy is measured in Erlangs. An Erlang is a ratio of the amount
of time a radio is in use over a given time interval. 1.0 Erlang
indicates the radio was in use for 100% of the selected time interval.
The dialogue window identifies the busiest cells over the selected
time interval and gives their respective occupancies in Erlangs. The
system average cell occupancy is also given.
Interval displayed is: May 16 between 15:00 and 16:00 hr.
