Summary
• This contribution provides result comparison of MAC calibration
of test 1-3 from variety of companies [1][2]
• This contribution also proposes a criteria for result alignment
• There are some parameter setting in the simulation scenario
document that may generate different interpretation, this
contribution clarifies these parameter settings
