Wait, are we sure about A? That sounds a bit off.

B could also be a factor, higher transmit power can mess with readings.

I practiced a similar question where the difference in protocols between adapters was mentioned. Could that be relevant here?

I’m not entirely sure, but I think the transmit power of the APs might affect the RSSI readings too.

I remember reading that site survey adapters are often more sensitive, which could explain the lower RSSI values on client devices.

I'm pretty confident that option A is the right answer here. The survey adapters are specialized for this kind of work, so they'll naturally have better performance than the standard client hardware.

Okay, I think I've got it. The survey adapters are designed specifically for site surveys, so they likely have better sensitivity than the regular Wi-Fi cards in the client devices. That's probably the most likely reason for the discrepancy.

This seems like a tricky one. I'll need to think carefully about the differences between the survey adapters and the client devices.

I'm just gonna go with option A. No need to overthink this one. Unless the APs were secretly using some kind of futuristic alien technology, then all bets are off.

All USB Wi-Fi adapters have greater sensitivity? That's a bold claim. I'm not buying it, option A seems more plausible.

Ah, I see! The site survey adapters use different protocols than the regular Wi-Fi cards. That's why the results don't match up.

I was thinking it might be the transmit power on the APs, but the question says the client devices show lower RSSI, so option A is more likely.
