61.2 LTE Signal Scanning
The LTE air interface uses OFDM as modulation method on the downlink. Synchronization Channels are used for service detection and synchronization, and Reference Signals (RS's) are used for channel estimation purposes.
The LTE signal scan provides the following metrics:
- SCH (PCI, PCIG, P-SCH RSSI, S-SCH RSSI, SCHRQ)
- RS (RSRP, RSRQ)
- CINR (SCH CINR, RS CINR)
- CFO
- Time Offset
