Android signal booster

The signal is listed in dBm signal strength and ASU. ASU stands for Arbitrary Strength Unit and is a value proportional to the received signal strength measured by the mobile phone. It can be translated to dBm, but there are different formulas depending on whether you are using 2G, 3G or 4G networks.14 Oca 2020

It measures roughly the same thing dbm measures. (You can convert ASU to dbm by dBm= -113+(2*ASU).) The higher the number, the better the signal .2 Mar 2015

-50 to -79 dBm, then it’s generally considered great signal (4 to 5 bars). -80 to -89 dBm, then it’s generally considered good signal (3 to 4 bars) . -90 to -99 dBm, then it’s generally considered average signal (2 to 3 bars). -100 to -109 dBm, then it’s generally considered poor signal (1 to 2 bars).25 Ağu 2020

GSM: dBm = 2 × ASU – 113, ASU in the range of 0.31 and 99. UMTS: dBm = ASU – 116, ASU in the range of -5.91 and 255 . LTE: The valid range of ASU is from 0 to 97.19 Mar 2019
