Excellent electronic supplies information database? Orthogonal frequency division multiple access OFDMA: Friends who are familiar with Wi-Fi should know that the empty port of Wi-Fi adopts orthogonal frequency division multiplexing (OFDM) modulation, that is, the whole bandwidth is composed of orthogonal subcarriers. In Wi-Fi 6, the 802.11 working group introduced OFDMA access from LTE. The addition of such an "A" word can be said to have brought a qualitative change to the network capacity. As shown in the figure on the left below, Wi-Fi 5-based OFDM can only allocate all the bandwidth in the channel to one user at any one time, even if that user's data needs do not need to take up all the bandwidth. When other users connect to the network, they need to wait for the…
