How to Measure Signal Strength? Best tips for 2022

If you want to measure your cell phone signal strength, then this article might be most helpful to you.

We usually get an idea of signal strength by seeing the signal bar of a cell phone, for instance, 1 signal bar means lowest signal strength, and full signal bar on your cell phone means highest signal strength, right?

And no signal bar on your cell phone means there is the lowest signal strength in your phone..but does the signal bar give accurate signal strength measurement?

However, in this article, we will know the accurate measurement of cell signal strength and you can measure it following some procedures. So, let’s get started.

What Does Cell Phone Signal Strength Mean?

In telecommunications, the cell phone signal strength is considered as the magnitude of an electric field at a reference point situated at an indicative distance from the transmitting antenna.

The signal power of the receiver or per length voltage received by the reference antenna is the cell phone signal strength. This is expressed in decibel milliwatts (dBm) or microvolts per meter dB (dBµV/m).

3G Signal Strength Range

Signal Range Strength Level Network Bars
-50 to -70 dBm Excellent signal strength 4 to 5 bars
-71 to -85 dBm Good signal strength 3 to 4 bars
-86 to -100 dBm Fair signal strength 2 to 3 bars
-101 to -109 dBm Poor signal strength 1 to 2 bars
-110 to -120 dBm Dead zone or no signal strength 0 bar

4G/LTE Signal Strength Range

Signal Range Strength Level Network Bars
-50 to -90 dBm Excellent signal strength 4 to 5 bars
-91 to -105 dBm Good signal strength 3 to 4 bars
-106 to -110 dBm Fair signal strength 2 to 3 bars
-111 to -119 dBm Poor signal strength 1 to 2 bars
-120 dBm Dead zone or no signal strength 0 bar

What Is A Good Cell Phone Signal Strength?

Cell signal strength is typically ranged from  -50 dBm to -110 dBm, and the dBm number as much as will be closer to 0, the cell signal strength will be considered stronger.

But generally, -30 to -85 decibels is considerably usable cell signal strength and if your cell phone signal strength is above the range, then definitely you need a cell signal booster.

A cell phone signal strength can enhance your cell signal power better than -70 dBm.


How to measure Android Signal Strength

Step 1

Go to Settings on your Android phone

Step 2

Then, Go to System Settings

Step 3

Tap on About Phone option

Step 4

Go to Status

Step 5

Then, select Sim Card Status

Step 6

Here you can see the signal strength that’s expressed in dBm or in ASU. You can convert ASU to dBm. dBm = -113+(2*ASU)


How to measure iPhone Signal Strength

Step 1

Ensure your wifi is off otherwise you can’t get you true cell signal strength of your iPhone

Step 2

Open the dialer

Step 3

Type *3001#12345#* and call this number

Step 4

You will find a menu appears on the screen and select the LTE option here

Step 5

Here again another menu will appear and Tap on the Serving Cell Measure from the options

Step 6

Here you can see a list of data continuously updating and from the list look for rsrp0 that’s the true signal strength received by the nearest cell tower. And you can also see here rsrp1 that’s also the true signal strength received by the secondary nearest tower.

Note: Remember that as much as the number of rsrp0 or rsrp1 is closer to -50, the stronger the true signal strength is. On the contrary, as much as the number of rsrp0 or rsrp1 is closer to -140, the weaker the true signal strength is.


How To Measure Cellular Signal Strength On a Computer?

Step 1

Plug in a modem in the computer or laptop (inserted a sim on the modem)

Step 2

Install the modem if it’s the first time on the computer and wait for the green signal

Step 3

Then go to a browser and type 192.168.1.1 and enter

Step 4

A home screen will appear and here you can find the signal strength

Step 5

Go to the signal strength and check


FAQs

What is dBm?

dBm the full form ‘decibel milliwatts’ is the unit of measurement of the signal strength of the radio, microwave, and fiber-optical network. The number of dBm is as much as closer to the Zero which means the signal strength will be as much stronger.

What is ASU in signal strength?

ASU the full form Arbitrary Strength Unit is the integer value proportional to received signal power by the cell tower. The valid range of ASU for LTE is from 0-97 and you can change ASU into dBM as dBm= -113+(2*ASU).


Summary

In fact, you can understand the signal strength of your cell phone by seeing the network bars on the home screen. But if you want to measure the actual signal strength of your cell phone, then you must follow the above steps properly.
