2.1 ATA8352 System Modes
The following table gives an overview of the system modes of the ATA8352 device. These modes were tested to compare the performance regarding Bit Error Rate (BER) and Packet Loss Rate (PLR). An additional criteria is the length of the data packet to align the Link Budget (LB) between the data communication packet and the ranging packet for the distance measurement.
| System Modes | Data Rate [Mbps] | Modulation | PRF [MHz] | PPS | Preamble Symbols | Sync Symbols | Application |
|---|---|---|---|---|---|---|---|
| Base mode | 1.0 | OOK | 1.0 | 1 | 64 | 15 | Base mode |
| Extended mode | 0.25 | OOK | 1.0 | 4 | 64 | 15 | Moderate data rate and improved sensitivity |
| Dual-frequency mode | 1.0 | PBFSK | 1.0 | 1 | 64 | 15 | Shortest frames and reduced power consumption |
| 4.0 | PBFSK | 4.0 | 1 | 224/176 | 127 | ||
| Extended Dual-frequency mode | 0.25 | PBFSK | 1.0 | 4 | 64 | 15 | Improved sensitivity |
| 1.0 | PBFSK | 4.0 | 4 | 224/176 | 127 | ||
| Proprietary mode1 | 0.5 | PBFSK | 4.0 | 8 | 224/176 | 127 | Highest security against physical layer attacks for verifier and prover operation |
| Proprietary mode2 | 0.25 | PBFSK | 4.0 | 16 | 224/176 | 127 |
