The formula is AS = Sp x Bwf x Bf x Plf x Avfwhere—

• “AS” means the appropriate sum;

• “Avf” means the Availability Factor, being the number in Column 2 of the table set out in Part 5 as determined by the Availability (in per cent) as set out in Column 1 of that table;

• “Bf” means the Band Factor, being the number in Column 2 of the table set out in Part 2 as determined by the range of frequency band (in GHz), if any, of a fixed link set out in Column 1 of that table in which the licensee’s band falls as declared by the licensee on application for a licence;

• “Bwf” means the Bandwidth Factor, subject to paragraph 3, being the number corresponding to the bandwidth (in MHz) of a co-ordinated bi-directional fixed link (or a part thereof) as declared by the licensee on application for a licence;

• “MPL” means the Minimum Path Length, being the number corresponding to the applicable (depending on the amount of data that can be transmitted over the bandwidth (“the data rate”) or over the channel width for analogue systems) length of the path (in kilometres) specified in Columns 2 and 3 of tables 1 or 2 set out in Part 4 as determined by the range of frequency band (in GHz), if any, of a fixed link set out in Column 1 of those respective tables in which the licensee’s band falls as declared by the licensee on application for a licence;

• “PL” means the Path Length, being the number corresponding to the distance (in kilometres) between two fixed points of the link as declared by the licensee on application for a licence;

• “Plf” means the Path Length Factor, being the number in Column 2 of the table set out in Part 3 as determined by the relationship between the PL and the MPL as set out in Column 1 of that table; and

• “Sp” means the Spectrum Price, being a fixed sum of £88 per 2 x 1 MHz bandwidth for each co-ordinated bi-directional fixed link.
