Correct answer: It is used in place of 802.11b/g when many nonoverlapping channels are required.
Why this is the answer
802.11a operates in the 5 GHz band, which offers significantly more non-overlapping channels compared to the 2.4 GHz band used by 802.11b/g. This makes 802.11a a better choice for high-density environments where many access points are needed to avoid co-channel interference and maximize throughput. Incorrect options: 802.11a was generally more expensive than 802.11b initially, not a lower-cost solution. 802.11a operates in the 5 GHz band, so it is not susceptible to interference from 2.4 GHz devices like microwave ovens. 802.11a is not directly compatible with 802.11b/g devices because they operate on different frequency bands.
