Yes, but... If you want a standard way of measuring RF (radio frequency) signals you use RF test equipment (signal strength meters, spectrum analysers). But as for computers, what are you going to believe? You may have wireless cards that give statistics about signal strength, but are they calibrated? Generally speaking, all they care about is a comparison of one signal against another, not an absolute signal strength reading. The bar graph that most WiFi devices show is a calculation of various factors (strength, quality/errors), each programmer does it their own way. It's rather like the aplaus-o-meters on television shows. You can get basic RF signal strength meters, but I'll lay odds that they just measure anything that triggers it within a certain bandwidth, it won't be an analysis of particular WiFi channels. You can get the opposite problems with proximity - too much signal, causing an overload of the front-end. Whether that be too close to your access point, or proximity to an interference source. I wonder how well WiFi cards work in proximity to each other. By way of a related example - ever used two broadcast radio receivers (AM or FM) near each other? You can get nasty squeals and other strange distortions of the signal as their IF and oscillator stages interfere with each other. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
