MAC calibration test 4 simulation results
This submission presents simulation results for MAC calibration test case 4 conducted in March 2015. The tests involve scenarios with different channel modes, traffic distributions, and transmission parameters to evaluate the performance of IEEE 802.11 networks. The results showcase throughput, time allocation in 40MHz and 20MHz modes, and the impact of RTS/CTS settings on data transmission. References to IEEE standards and simulation scenarios are also provided.
