The key identifying parameter for each base site is the ‘LAC’. This is compared to the LAC data reported
by the TETRA radio to determine which base site is currently being used. To delete a base site click on the
symbol in the main window.
If more than one base site has an identical latitude and longitude to other base sites then they are
assumed to be sectors of a single base site and are displayed on the map as a single symbol. The antenna
symbol displayed on the map is defined by the Beamwidth, Direction and Icon Size parameters. The Icon
Size is intended purely to make overlapping antenna patterns clearer.
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.
Neighbour Cell frequencies that appear for more than one LAC are coloured red, again 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 base site data may be exported to a comma separated text file by clicking the ‘Export’ link. There is an
option to compress the exported file into a standard zip file format.
Super Admin users also have access to the following functions:
Large lists of new base site planned frequencies may be imported by clicking on the ‘Import Planned
Frequency Lists’ link. The import file should be a text file with the following format:
LAC frequency1,frequency2..frequencyN
With each base site LAC being on a new line. There is an option to clear the existing planned frequency
list.
The ‘Used Frequency’ and ‘Neighbour cell’ lists may be cleared by clicking on the relevant links. These will
delete all of the data in these lists for all base sites so should be used with caution.
