Measuring cellular signal strength on Samsung Galaxy phone is possible in the same way as on iPhone. No professional skills or special equipment are required for this. Just run a few simple commands. After that, you can order a suitable repeater or call us for advice.
Measuring the signal strength on an Samsung Galaxy is necessary for accurate diagnosis of missed calls, poor hearing and other such problems. The cause is not always an insufficient signal level. Therefore, you need to determine the level and the frequency range in which the nearest base station operates.
After measuring the signal, you can choose a mobile signal booster or contact us.
How check the 4G signal level on the Samsung Galaxy
First, turn off Wi-Fi. Make sure your phone is in 4G mode (4G icon on your phone).
Dial the code *#0011# and press the “Call” button. This will take you to the Samsung Galaxy’s service menu.
Select SIM card (STACK 1 or STACK 2).
You will see the following information if the phone works in 2G mode (GSM-900, GSM-1800).
Sign «Е» – 2G signal;
2G-BASIC Info – 2G signal;
PGSM900 – GSM-900 (frequency range);
BCCH arfcn: 52 – GSM-900 active channel number;
Lvl: -85 – GSM signal level in dBm;
Tx_Pwr_Lvl: 30 – Transmission signal level (the lower this value, the higher the signal).
You will see the following information if the phone works in 3G mode (UMTS2100, WCDMA, HSPA+).
Sign “H +” – 3G signal;
uarfcn: 10563 – UMTS2100 channel number;
Ec/Lo: -8 – Received/reflected signal ratio (Must be greater than -10. For example, Ec/Lo: -5 is good.);
RSCP_CPICH: -104 – Active channel incoming signal level;
WCDMA (2100) – 3G signal in UMTS2100 standard.
4G LTE Mode
You will see the following information if the phone works in 4G LTE mode.
Sign “4G” – 4G signal (LTE);
LTE-BASIC Info – 4G signal (LTE);
Band: 20 – LTE 800MHz
RSRP: -93 – Signal (dBm) from active BS (average over channels) ≥ -125 dBm.
RSRQ: -12 – Signal quality (dB) from the active BS (the more the better)
RSSI: -63 – Received signal strength (dBm);
SINR: 12 – signal/noise ≥0;
If the channel number is in the range 1200-1949, then the phone is in LTE1800 mode. If the channel number is in the range 2750-3449, then the phone is in LTE2600 mode. If the channel number is in the range 6150-6449, then the phone is in LTE800 mode.
||Generation||Frequency||ARFCN value (UARFCN or EARFСN)|
|GSM-900||2G||900 MHz (Band 8)||0.. 124|
|GSM-1800||2G||1800 MHz (Band 3)||512.. 885|
|UMTS-900||3G||900 MHz (Band 8)||2937… 3088|
|UMTS-2100||3G||2100 MHz (Band 1)||10562.. 10838|
|LTE-800||4G||800 MHz (Band 20)||6150.. 6449|
|LTE-1800||4G||1800 MHz (Band 3)||1200.. 1949|
|LTE2600 FDD *||4G||2600 MHz (Band 7)||2750.. 3449|
|LTE2600 TDD **||4G||2600 MHz (Band 38)||37750.. 38249|
* – FDD (Frequency Division Duplex) uses frequency division of the DL / UL channels, which allows to amplify this signal with an active amplifier (repeater).
** – TDD (Time Division Duplex) uses DL / UL time division multiplex, which makes it impossible to amplify this signal with an active amplifier (repeater).
We recommend amplifying the mobile signal with 4G Signal Repeaters from Rangeful.
