Section titled “Parameters”“-” or - indicates the parameter is invalid under the current condition.
| Parameter | String | Description |
|---|---|---|
| <celltype> | "servingcell" "neighbourcell" | The information of 3G/4G/5G serving and neighbour cell towers. |
| <state> | "SEARCH" | Searching but could not (yet) find a suitable cell. |
| "LIMSRV" | Camping on a cell but has not registered. | |
| "NOCONN" | Camping on a cell has registered on the network, and it is in idle mode. | |
| "CONNECT" | Camping on a cell and registered on the network, a call is in progress. | |
| <is_tdd> | "TDD" & "FDD" | The LTE network mode. |
| <MCC> | Number format | Mobile Country Code (first part of the PLMN code). |
| <MNC> | Number format | Mobile Network Code (second part of the PLMN code). |
| <LAC> | Integer type | Location Area Code. The parameter determines the two bytes' location area code in hexadecimal format (e.g., 00C1 equals 193 in decimal) of the scanned cell. Range: 0–65535. |
| <cellID> | Cell tower ID | The parameter determines the 16-bit (GSM) or 28-bit (UMTS) cell ID, which range is 0–0xFFFFFFF. |

| <uarfcn> | UTRA-ARFCN | The parameter determines the UTRA-ARFCN of the cell that was scanned. |
| <earfcn> | E-UTRA-ARFCN | The parameter determines the E-UTRA-ARFCN of the cell that was scanned. |

| <RAC> | Integer type | Routing Area Code. Range: 0–255. |
| <RSCP> | Number format | The parameter determines the Received Signal Code Power level of the scanned cell. |
| <ecio> | Number format | Carrier to noise ratio in dB = measured Ec/Io value in dB. |
| <RSRP> | Negative number | Indicates the signal of Reference Signal Received Power in both LTE and 5G-NR modes. Range: -140 to -44 dBm. The closer to -44, the better the signal is. The closer to -140, the worse the signal is. |
| <RSRQ> | Negative number | Indicates the signal of Reference Signal Received Quality in both LTE and 5G modes. Range: -20 to -3 dB. The closer to -3, the better the signal is. The closer to -20, the worse the signal is. |
| <RSSI> | Number format | Received Signal Strength Indication. LTE only. |
| <SINR> | Number format | Indicates Signal-to-Interface plus Noise Ratio. The conversion formula for actual SINR is Y = (1/5) × X × 10 - 20 (X is the value queried by AT+QENG, and Y is the SINR value). Range: -20 to 30 dB. |
