Figure 57: Configuring Network parameters
The ‘Grid Ref’ parameter is used to specify the mapping system that is used to produce the square km
analysis. For the UK this should be set to OSGB.
The ‘Frequency representation’ parameter is used to set the method of displaying radio channel
frequencies: either in MHz or channel number. If channel number is selected then the Offset and Spacing
in MHz must also be specified separately for frequencies in the 300MHz and 400MHz bands.
The System Administrator will always view frequencies in MHz because of the potential of confusion from
seeing several different networks with different settings.
The expiry period for frequencies in the Used Frequency list and the Site Neighbour list may be specified.
Note that the ‘Used Frequency’ list and ‘Site Neighbour’ list may be cleared by a Super Admin user from
the Base Sites page. See section 2.2.
The distance limit for the lines linking to base sites using the same frequency may be specified. See
section 2.4.
