The wireless throughput of an AP is primarily influenced by physical layer factors such as:
A: Spatial Streams: More spatial streams allow more simultaneous data channels.
B: Frequency Bandwidth: Wider channels (e.g., 40 MHz, 80 MHz, or 160 MHz) allow more data to be transmitted.
D: SNR: Higher signal-to-noise ratio leads to higher modulation levels and throughput.
Option C (CPU performance) affects the system's ability to process traffic at the application or system level, but not the physical-layer wireless rate. CPU performance may affect total packet forwarding but is not directly a factor in wireless transmission rate.
