11. doc.: IEEE 802.11-14/1192r5 Submission The functional test results from different parties are generally aligned. –MAC/PHY Framing aligned very well –Deferral in light collision case aligned very well –Deferral in intensive collision case (with hidden node) is not so well aligned. But we shall reduce the gap among different parties to allow the simulator could be still pretty well aligned when more functions are added and applied to more general performance test scenarios.
