This is just a memorization question: The three elements that determine Air Time efficiency are:A. data rate (modulation density) or QAM Higher data rates, achieved through advanced modulation techniques like Quadrature Amplitude Modulation (QAM), allow more data to be transmitted in less time, improving air time efficiency.C. channel bandwidth Wider channel bandwidths (e.g., 40 MHz, 80 MHz, or 160 MHz) enable higher throughput, reducing the time required to transmit data and thus improving air time efficiency.D. number of spatial streams and spatial reuse More spatial streams (via MIMO technology) and spatial reuse (e.g., in 802.11ax) allow multiple devices to transmit simultaneously, optimizing air time usage.
