| + | ==4G (LTE)== |
| + | |
| + | For 4G service mode, there are three relevant measurements: |
| + | |
| + | *RSSI - indicates the received signal strength |
| + | *RSRP - the Reference Signal Received Power is the power of the LTE Reference Signals spread over the full bandwidth and narrowband |
| + | *SINR - Signal to Interference plus Noise Ratio (A minimum of -20 dB SINR is needed to detect RSRP/RSRQ) |
| + | *RSRQ - Reference Signal Received Quality is a C/I type of measurement and it indicates the quality of the received reference signal |
