Step 3: Scanning a signal Explanation The device is connected to a 4G band. The band is 7 and the frequency is 2600 MHz. RSRP - Reference Signal Received Power (the signal strength without noise and interference) measured in decibel meter (dBm). The signal is visualized in the signal bar below the data.
4. View, Test and Upload/Download Scans Explanation Band 7 / 2600 MHz Referenced Signal Received Power (RSRP) is -82 dBm with Min & Max values below. Referenced Signal Received Quality (RSRQ) is -7dB with Min & Max values below. Public Land Mobile Network (PLMN) is 240007: The channel is 2850. Scanned Network (Operator) 4.1 Communication Test Ping to test network communication.
4.3 Download Signal (Local) If logging is turned on while sending is turned off, the logged scans will be stored on the device.
