As a good example I was down in an area just yesterday that mentioned of poor signal and I initially went down with my nexus 7 and my analyzer program and could barely get -80 dbm. I found it very odd so I went back and got my laptop with Ekahau and my ekahau usb-300(?) nic and was easily getting 65-68 dbm.
I too should have surveyed with a lower power setting on my nic.

This blog post at aerohive has good info on determining transmit power on devices. Interesting that the report lists different power levels at different frequencies.

Coming in a little late on this thread, but Tristan brings up an excellent point. We are dealing with multiple areas in our dorms where AirMagnet Survey with the AirMagnet a/b/g/n card had a much better RSSI/SNR than the student with an iPad or iPhone has. What we should have done when surveying was to turn down the TX power to something like 25mW, which would more closely mimic a tablet or smartphone.
We are in need of a survey tablet upgrade and currently looking at a Dell XPS with the built-in Intel® Dual Band Wireless-AC 7260 since that appears to have direct support within AirMagnet. But I'm considering also purchasing something like a Nexus 5 smartphone and using that along with the tablet to check RSSI. I would prefer to use an iPhone since that's what the majority of students have, but from what I can tell there's still no decent App that will give RSSI values.
Curious what folks think of that strategy. Hopefully this is close enough to the main topic to not be considered hijacking. I had been meaning to get an email out on this topic.
Thanks,

- Hi all,
What device or test equipment is being used for the RSSI value? If we see -65dBm on a Fluke AirCheck, we’re lucky to get -72dBm on an Intel 5100 in an HP laptop, as an example. We’d like to pick a specific device, eg, an iPad and create standard measurements on such a device so the customer is empowered to report a fault based on data they have available.

- We are going into dorm rooms over winter break to review ap placement. Do any of you have a policy (written or unwritten) that sets a minimum RSSI for a space? For example, if the RSSI is -65 or lower then you shuffle or add an ap to the area?
