802.11 Part 9: OFDM and MIMO

In this video we will talk about two fundamental ideas in moving 802.11 speeds higher, improving SNR (signal to noise ration) and changing the way we think about channel construction: Multiple IN multiple OUT (MIMO) and Orthogonal Frequency Division Multiplexing or OFDM.
