wl1271 AP - beacon signal strength

Bernard Seller

Other Parts Discussed in Thread: WL1271

In an experiment I have a wl1271 AP (Linux Kernel 3.2, compat wireless 3.3, Pandaboard, Ubuntu)

on a laptop I am running the inssider tool and plotting the signal strength for the Beacons received from my wl1271 AP

The signal strength  varies by almost 12 dB

I am guessing that there are various parameters that can be tweaked in the wl12xx driver so the signal strength can be more stable

(I am hoping for variations of no more than 4dB)

(for longer distance 12dB can result in lost connection)

DO you have suggestions on what parameters I should "tweak" to achieve a more stable signal strength?

thanks

Bernard

    Hi Bernard,,

    I had not tested the same release (SW+HW) that you have, however had tested similar WLAN releases with other platform and we don’t see such variation in RSSI. But the difference between the tests we do is done in controlled environment (RF chamber). And for measurement we use WLAN sniffers. I guess that your measurement done in open Air which might results with different test results and conclusions.  In addition I downloaded the tool you have (cool tool) and I saw that other commercial (in open Air environment) has large RSSI variance, have you seen that as well with commercial AP?
