Frequencies may be displayed in MHz or channel numbers. The choice is set by the Sysadmin user for
each network (see section 2.5).
The Planned Frequencies for a base site are defined by the user however the Used Frequencies and
Neighbour Cell frequencies are collected by the probe and are updated for each site as new data is
gathered.
Used Frequencies that do not appear in the Planned Frequency list are coloured red indicating that the
network may not be configured correctly.
Frequencies that appear in the Used Frequency and Neighbour Cell lists are updated as soon as a new
frequency is logged however if a frequency is not logged for more than a certain period then it is removed
from the list. This period is set by the SYSADMIN with a default of 3 days (see section 2.5). The only
exception to this is if no neighbour cell lists have been logged for the base site in which case the
frequencies do not expire.
The Handover Count lists the percentage of handovers occurring from this base site to the listed base site
and gives a good indication of which neighbour cells are critical. In addition the number in brackets gives
the number of failed handovers to the listed base site.
When a frequency is clicked the map displays bumpy lines from the event or base site to the other base
sites using that frequency within a radius specified by the SYSADMIN (see section 2.5).
