2. Submission doc.: IEEE 802.11-14/0623r1 May 2015 Guido R. Hiertz, Ericsson et al.Slide 2 Abstract This submission presents our results of the TGax “Box 5” [1] simulation tool calibration test. We follow [2] and simulate scenario 6 (“Enterprise Network with OBSS”) of [3]. As with previous studies [4] the results reveal that our simulation tool behaves equal to other tools.
