It measures the same thing as dBm, but it is expressed in a more linear way. You can use this formula to convert ASU into DBM: DBM =-113+(2 * ASU), for example:-63dbm25asu-63dbm =-13+(2 * 25).
Under the GSM network, the DBM of network transmission is-1 13+2 * ASU.
Under UMTS network, dbm=asu- 1 16,
Under the LTE network, (ASU- 14 1)
Extended data:
The asu of the mobile phone should be 6.5, and if rounded, it should be 7. So, in general, you can see 10-30, which is normal. The larger the number, the better the signal strength.
Independent signal units are also analog signals, corresponding to digital signals. The latter takes discrete logical values, while the former can get continuous values. The concept of analog signal is often used in the field of electricity, but it is sometimes used in classical mechanics, aerodynamics, hydraulics and other disciplines.
Analog signals use some physical characteristics of objects to express and transmit information. For example, a non-liquid barometer uses the spiral position of a pointer to represent pressure information. In electricity, voltage is the most common physical medium for analog signals. In addition, frequency, current and charge can also be used to represent analog signals.
