I\'m playing around with reading the signal strengths in a small Android App, and was wondering if anyone has tested this (or just knows) of the documented values (0-31, 99)
The values are defined in the GSM standard TS 27.007, section 8.5 (Google it, or see here)
From the standard:
0 -113 dBm or less 1 -111 dBm 2...30 -109... -53 dBm 31 -51 dBm or greater 99 not known or not detectable
Which means - 0 is low, 31 is good.
