A factory voice call on a rolling cart drops each time the cart moves from one access point to the next. The second radio uses a different security mode, and the two cells barely overlap. Which fault fits?
Select an answer to reveal the explanation.
Short Explanation
A voice call should change radios the way a car changes lanes, without hanging up. Your cart drops at every boundary because the next radio uses a different security mode and the cells barely overlap. Blaming only the coverage, or only the security mode, drops half of what the stem measured.
Full Explanation
Wireless roaming lets a client leave one access point and join another while a call keeps running. The radios need compatible security and enough overlap that the client associates to the next radio before the first is gone. This cart loses the call at every boundary. The second radio uses a different security mode, and the cells barely overlap. Both facts are in the stem, so the fault is the roam, not one of them alone. Coverage alone ignores the security mismatch, which stops a client from continuing the session even where the signal is present. The security mismatch alone ignores the gap where neither radio holds the cart. A unique network name would also break roaming, and the stem does not say the second radio advertises a different name. Exam caveat: fast roaming still requires matching security. A controller cannot roam a client onto a radio that demands a different mode. Operational check: match the security on both radios, then survey the boundary and confirm the cells overlap where the call drops.
