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

D seems a bit too broad, not all USB adapters are better.
SA

I think C makes sense too, not all cards support the same protocols.
AL

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

A is definitely true, survey adapters are usually more sensitive.
DA

I feel like option D is too broad. Not all USB adapters are more sensitive than internal ones, right?

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.
DE

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.

Hmm, I'm a bit confused. I thought all USB Wi-Fi adapters were more sensitive than internal ones, but this question is making me second-guess that.

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.

User 2: Yeah, I agree. The regular Wi-Fi cards in client devices may not be as good for site surveys

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.

A) USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices
AL

I think the issue might be that USB Wi-Fi adapters designed for site surveys have better sensitivity than regular Wi-Fi cards.
MI
Milly

I disagree, I believe it's because regular Wi-Fi cards in client devices don't support the same protocols as survey adapters.
ST
Stefany

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.

The USB Wi-Fi adapters used for the site survey probably have better sensitivity, which is why the RSSI values are higher. Makes sense to me.
