Modification of the chosen threshold BER (10-3,10-6,RBER) changes the thermal fade margin of the link. It seems that this figure is then used to calculate the Worst Month SESR.

The bit-error probability is a function of the SNR of a link, with noise initially taken as the thermal noise floor of the receiver. BER is in turn a function of the resulting error distribution.

An SES is defined (as per the ITU)in terms of the rate at which an error occurs (10-3 or indirectly through the rate such that 30% of blocks in a given second contain at least 1 error). Given this, I believe that Pathloss provides an accurate calculation of SESR only when 10-3 thresholds are used.

Am I missing something - or is this an accurate deduction?

Default SESR Calculation method

I am not sure I understand you correctly, but it is expected that the Fade Margin would change since radios have 2 Threshholds, 10-3 and 10-6.
