What do you mean by 'margins' in this context? Generally, the spectrum managers ask for X dB(uV/m, based on complaint levels (probably with a built-in 'safety factor') and the equipment manufacturers propose (X+10) dB(uV/m)[**], based on what they can achieve at low cost (probably with a built-in 'safety factor') and some compromise is reached. [**] Except for power-line communication, where the opening bid was (X+60)dB(uV/m)! -- Regards, John Woodgate, OOO - Own Opinions Only.
