Notes to Table I-6:
(1)Use ISO 3166-1 alpha-2 country codes.
(2)In case of sum and difference pattern antenna give angle between the two maxima of the difference pattern.
(3)Two beam antenna: enter difference between maximum gains. Sum and difference pattern: give difference between maximum gain in the sum-pattern and average gain for the two maxima of the difference pattern.
(4)IBAD frequency separation is the difference in MHz between two filters used for measuring the amplitude difference in the radio channel (preferably at equal distance from the centre of the radio channel). In case of IBPD the difference between the maximum and minimum frequency used should be given.
(5)If an equalizer is used, the “time percentage of BER=...” should be reported after removal of the equalizer improvement. Note that no FEC should be applied.
(6)Duration is the total time of valid measurements for this dataset, expressed as a real number (e.g. 339.888 days).
The ratio of duration to the period identified by the start and the end dates of this dataset is the availability (e.g. start=2001/1/1, end=2001/12/31, duration= 339.888 days corresponds to 93.12 % availability).
(7)Submissions should comply with the acceptance criteria specified in Rec. ITU-R P.311.
[+]In addition to the tables provided in this document the submitter is requested to provide the data files according to the instructions available on ITU-R SG 3 Web page: Study Group 3 databanks - DBSG3.
