How can I have a dbm of -76 and an asu of 0-2?

[Android Central Question]

I thought that absolute value dbm was inversely proportional to asu. Please enlighten me.

Asu is an approximate number (read:guess). dBm is an actual measure. -76dBm means that you're fairly close to the tower. (I have a solid signal, and -99 dBm [with a 41 asu, so the -113+(2Xasu) doesn't work that closely. [And as the signal varies (same tower), there's no simple formula to make it track. In an LTE network (almost all of them now), one formula is (ASU - 143) < dBm ≤ (ASU - 140), but that still doesn't track with real-world numbers.])

Just use the dBm, which is an actual measurement of the strength of the signal. Anything stronger than about -105dBm (any smaller negative number) is a solid signal.
