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) which value is better.
By asking which is better, I mean, does 0 represent no signal, or perfect signal.
I’m running an HTC Incredible on Verizon, so I can confirm the 99 is no GSM antenna, but I could not find any other items on GSM
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.
