Simulating advanced Wi-Fi features – MIMO and OFDM

In this section, we will focus on an 802.11ac simulation setup and evaluation. As part of 802.11ac, we will configure the advanced Wi-Fi features of MIMO and OFDM supporting VHT MCS values in ns-3 simulations to improve STA throughput. In particular, we will discuss how enabling MIMO helps to improve throughput by using multiple antennas to handle parallel transmissions or reception. Besides transmitting signals at VHT MCSes, the receivers should also receive at good SNR. In these cases, we discuss how enabling MIMO helps transmitters to use HT MCS values. Specifically, we will do the following activities to test the MIMO and OFDM features for an 802.11ac Wi-Fi LAN:

• Using the pkt-11n-ac-test.cc source code and making the following necessary changes to simulate 802.11ac networks
• Configuring 802.11ac as the Wi-Fi standard
• Uncommenting the lines of code related to SU-MIMO configuration in pkt-11n-11ac-test.cc
