What do iPhone field test numbers mean?
What do iPhone field test numbers mean?
The number you see displayed for the rsrp0 in field test mode is a measurement in decibel milliwatts. It’s a negative number that should fall between -40 and -130. The closer this number is to zero, the stronger the signal, so a signal strength of -60 dBm is stronger than -80 dBm.
What is a good signal quality number?
Cell phone signal strength is measured in decibels (dBm). Signal strengths can range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal. In general, anything better than -85 decibels is considered a usable signal.
How many bars should my iPhone have?

- Tap Settings.
- Tap About Phone.

- Your dBm is under Signal strength.
What is a good signal strength LTE?
RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good).
What is a good LTE signal strength?
RSRP – the Reference Signal Received Power is the power of the LTE Reference Signals spread over the full bandwidth and narrowband….4G (LTE)
| RSSI | Signal strength | Description |
|---|---|---|
| > -65 dBm | Excellent | Strong signal with maximum data speeds |
| -65 dBm to -75 dBm | Good | Strong signal with good data speeds |
Is 2 bars of signal good?
-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). -110 to -120 dBm, then it’s generally considered very poor signal (0 to 1 bar).
What does 4 bars mean on iPhone?
Cell Phone Bars: What They Really Mean For example, you iPhone could show three bars while your friend’s Galaxy might show four. This doesn’t mean one cell phone has better reception than the other. All it means is that at that place and time, Samsung reads “-65dBm” as four bars, while Apple shows them as three.
Why do I only have 1 bar on my iPhone?
