Benefits of 802.15.4z LRP/HRP

IEEE 802.15.4z HRP & LRP

coexistence enables a significantly larger ecosystem and ultra-low power applications (+ energy harvesting)

Learning from history of wireless

BT evolved towards
BTLE (low cost + ultra-low power communication)

We combine both flavors at the very beginning!

Secure ranging

IEEE 802.15.4z LRP

Based on Distance Bounding protocols and Distance Commitment
Formally proven resilience against strong attacker
- Basin et al., ACM Trans. Sec., 2011
- Tippenhauer et al., WiSec 2015

IEEE 802.15.4z HRP

Based on correlation of random sequence (STS)
- Security parameters not defined
- Security guarantees not clear
No security levels defined in the standard
No publicly available information
Proprietary solutions are needed

Power consumption

UWB LRP

Peak current @3V
- TX 9 mA
- RX 18 mA
- Post processing 0 mA
Energy per ranging session (two-way)
- < 4 uJ
- no additional message exchange

UWB HRP

Peak current @3V
- TX 100 mA
- RX 140 mA
- Post processing 13 mA
Energy per ranging session
- < 10 - 15x higher
- requires multiple messages
