I'm unintentionally obtuse.
What is this signal strength 98% of?
I'd guess it means that 98% of the transmitted signal intensity is
being received by the wireless card. Although I have to admit, I do
wonder how that is calculated, and whether it takes into account the
1/r^2 fall off of signal emitted in the full sphere.
This explains it pretty well:

It may be more than you want to know.
