Show answer & explanation
Correct answer: A
To solve this, match each 802.11 standard with its typical data rate:
1. 802.11b: Operates at a maximum speed of 11 Mbps, which corresponds to (Q).
2. 802.11a/g: Operates at a maximum speed of 54 Mbps. Option (R) lists '54 Gbps', which is a typo for Mbps, so it matches (ii).
3. 802.11ad (WiGig): Operates in the 60 GHz band with speeds up to approximately 7 Gbps, matching (P).
4. 802.11ac: While typically much faster (up to several Gbps), in this specific question context, it is matched by elimination to (S) 3.5 Mbps.
Thus, the correct matching is (i)-S, (ii)-R, (iii)-P, and (iv)-Q.
