not the fading margin, etc.). This tool has been used to obtain the results (see section 2.3) of
these calculations.
2.2. SYSTEM DESCRIPTION AND PARAMETERS
It is not the aim of this report to describe each analyzed technology but only give the values of
the parameters which have been agreed for calculation.
Most of these parameters were set in the second meeting of the Experts Group [3], some
improvements and additional settings have been made during following audio teleconferences.
In some cases, the Group was unable to chose whether to use a typical, best or worst value for a
parameter. Therefore a plausible value was chosen and called the “reference” value. A range of
values for some system parameters was also selected. The analysis will initially assume the
“reference” value and any further sensitivity analysis would encompass other values within the
range as appropriate for the technology.
For example, the Group considers the interference threshold “reference” value of 1dB within a
range between 0.5 to 3 dB.
