Good: Similarly, -71 to-85 dBm on 3G is considered good and so is -91 to -105 dBm on 4G/LTE. Is this good or bad? Signal strength is shown in units of “dBm” and “asu”. HowardForums is a discussion board dedicated to mobile phones with over. See chart above for value range from excellent to worst. In dB, LTE - The Reference Signal Received Quality has a range from -40dB (bad) to -3dB (good) - see chart above for actual assessment. Also have app called coverage map. The strength of a cellular signal can be accurately measured using decibel milliwatts, or dBms. The valid range of ASU is from 0 to 97. Signal Strength . Hence, attach the ‘F’ connector to the end of the coaxial cable, and then to the input connector on the measuring device you … It seems that dBm is indirectly proportional to asu. Measured in dBm, a signal of greater than -70 dBm is considered an excellent signal in all networks.

Can't find anything on it! See also: Map your wireless network with a heat mapper. This is still good, reliable signal strength.-67 dBm: This is the minimum value for all services that require smooth and reliable data traffic. They aren't called "arbitrary signal … If your outside signal ranges from:-50 to -79 dBm, then it's generally considered great signal (4 to 5 bars). Required for-60 dBm. at this point it gives you the wifi signal strength my phone states -111 dbm 29 asu. A poor signal will be -100 dBm or worse in 3G networks and -110 dBm or worse in 4G networks. My carrier is AT&T. RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good). Ideal Signal Strength. android signal-strength Share. This is still good, reliable signal strength.-67 dBm: This is the minimum value for all services that require smooth and reliable data traffic. dBm = ASU - 116, ASU in the range of -5..91 and 255. The closer that number is to 0, the stronger the cell signal. I have seen readings nearer my closest cell tower while in my car as high as (-60 dBm 45 asu) a full 5 bars. Fair:-86 to -100 dBm on 3G is fair and -106 to -110 dBm on 4G/ LTE is also fair. Wanted: old barnfind VWs and Sports cars , Current Phone: AT&T XS Silver 256GB. This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. Whereas, anything post -90 to -100 dBm falls in the territory of weak signal strength. • -91dBm to -100 dBm – Poor Signal (good voice data, marginal data with drop-outs) • -101dBm to -109 dBm – Very poor Signal ( voice may be OK, no data) • -110dBm to -113 dBm – No signal. ...The real determinant is just normal use. So what signal strength should you shoot for? Different signals have a different range in which they work the best. On LTE, ASU 99 means that the signal strength cannot be determined. • Above -90 indicates basic communication is possible. In UMTS networks, ASU maps to RSCP level: (received signal code power).
