Question 32

What 802.11 PHY uses available space in very low frequency ranges that is not in use at the time by broadcast video signals?

    Correct Answer: D

    The 802.11 PHY that uses available space in very low frequency ranges not in use at the time by broadcast video signals is TVNT. DSSS operates in the 2.4 GHz range, which is not considered a low frequency. DMG and SIG are not associated with utilizing low-frequency ranges designated for broadcast video signals. TVNT (often mistaken for TVHT) fits the specified requirement.
