GPRS, EDGE, UMTS, HSDPA, HSUPA, HSPA+
 
Android ASU range:
 from 0 to 31 ASU
 
Android RSSI (Received Signal Strength Indikator) dBm:
 from -51 dBm to -113 dBm.
 
The value 99 is equal to unknown or not supported.
 
 
RSSI [dBm] = (2x ASU) - 113
 
 
 
The bars in the app used the range from 0 ASU to 24 ASU.
 
 all bars are shown if the ASU is greater than 16 or 17.
 
LTE Android ASU range:
from 3 to 95 ASU
 
LTE Android RSRP (Referenz Signal Received Power):
 from -137 dBm to -45 dBm.
 
under LTE RSSI is not used and the range is much bigger.
 
 
RSRP [dBm] = ASU - 140  
ASU = RSRP [dBm] + 140
 
 
0 - 1 ASU, signal strength is very, very weak         
2 - 3 ASU, signal strength is very weak         
4 - 5 ASU, signal strength is weak         
6 - 7 ASU, signal strength is normal         
8 - 10 ASU, good signal strength       
11 - 12 ASU, very good signal strength       
13 - ... ASU, signal strength is perfect

Easier ArrayBuffer <-> String conversion with the Encoding API 

The Encoding API makes it simple to translate between raw bytes and native JavaScript strings, regardless of which of the many standard encodings you need to work with!

Thank to +Jeffrey Posnick for the post!
