reliability methods in pathloss4.0

[mohamad]

dear all friends in this forum;
in worksheet module of pathloss4.0 and in reliability options menu,when I choose ITU P530-9 as reliability method with ITU-T G821 as calculation method,the worksheet page has green correct sign but if I choose ITU-T G826 then the MW links will corrupt;
is there any mistake in my planning and design?
Thanks a lot for your help;
with regards
mohamad

If you click on the red X sign it will give you an answer what's the problem.
And I'm sure that the problem is that you don't have G.826 model of radio equipment. For G.826 you also need certain parameters necessary for calculations such as alpha1-3, residual BER, threshold level for residual BER, etc...
Get a copy of ITU-R P.530-9, for example:
http://seattlewireless.net/docs/P-53...ht_systems.doc
and see how the system calculates SESR, ESR and BBER, and what are the parameters that you need. Afterwards, you can compare it with the radio model and see what is missing.

Thank you a lot. your idea is right.
I click on the red X so it say me no 826 equipment parameters
