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.
