Signal Quality over 100%?

[lampmaster1]

Is the signal strength supposed to be over 100 percent?

Yes. There is no universally accepted definition for what signal quality (%) should be so I just implemented the one proposed by Microsoft. Signal quality is really just a relative measure of signal strength (in the case of my program it linearly maps 0 through 100% to -100 through -50 dBm RSS). Therefore, if the RSS is greater than -50 dBm the quality is supposed to be over 100%.

The signal quality is mostly just included for convenience (since it can help gauge how strong the network is compared to an average network). When evaluating the signal strength of your antenna, I recommend using the signal strength (RSS) reading which is in dBm (not percent). Since RSS is well defined and doesn't depend on implementation.

Other programs have a wide variety of implementations of signal quality (from linear to exponential scales). In the next version, I could implement the same definition of signal quality as Wifi Info View if we think that would be more useful (and if I can find documentation for it somewhere)?
