5 IEEE 802.15.4z-2020 UWB Standard
The IEEE 802.15.4z-2020 UWB standard is an amendment to IEEE Standard 802.15.4-2020 and defines two profiles, High-Rate-Pulse (HRP) and Low-Rate-Pulse (LRP) for UWB communication and ranging. The following table lists the LRP modes defined in the amendment and the subset of these modes, which are comparable to the system modes of the ATA8352 device for the verifier and prover modes, data communication and TDoA.
| IEEE802.15.4z Operating Modes | Data Rate | Modulation | PRF [MHz] | PPS |

| Base mode | 1 Mbps | OOK | 1.0 | 1 | no | yes | Base mode |
| Extended mode | 250 kbps | OOK | 1.0 | 4 | no | yes | Moderate data rate and improved sensitivity |
| Long range mode | 31.25 kbps | PPM | 2.0 | 32 | no | no | Best sensitivity |
| Dual-frequency mode(1) | 1 Mbps | PBFSK | 1.0 | 1 | no | yes | Shortest frames and reduced power consumption |

| 8 Mbps | PBFSK-16PPM | 2.0 | 1/4 | no | no | ||
| 10 Mbps | PBFSK-32PPM | 2.0 | 1/5 | no | no | ||
| Proprietary mode1(2) | 500 kbps | PBFSK | 4.0 | 8 | yes | yes | Highest security against physical layer attacks |
| Proprietary mode2(2) | 250 kbps | PBFSK | 4.0 | 16 | yes | yes | |

Note:

The modes implemented in the ATA8352 device have some deviations to the definitions in the amendment, meaning, for the preamble and the synchronization, but are comparable for data rate, modulation, PRF and PPS.
