Achievements and recognition

  • Pioneer of secure low power single-chip UWB technology
  • Mass production UWB IP in the automotive industry
  • The only scientifically proven secure distance measurement UWB solution
  • Lowest power consumption with 10x less than any other competing UWB chips
  • Smallest UWB silicon area, including both RF and Digital
  • Co-shaping the UWB regulation and standardization since 2012

Expertise and offering


LRP UWB (Low Rate Pulse)

  • Mass produced AEC-Q100 qualified UWB IP for IoT devices (keyfobs, smart watches)
  • Scientifically proven secure ranging
  • Lowest power consumption on the market
  • Smallest silicon area on the market

HRP UWB (High Rate Pulse)

  • Detailed IEEE 802.15.4 HRP UWB knowledge
  • How to secure HRP PHY (Patents & Know-how)
  • Low power RF architecture & circuits for HRP PHY and co-integration with LRP PHY

HRP/LRP (IEEE 802.15.4z)

  • IEEE 802.15.4z dual HRP/LRP
  • TigrisTM RF Architecture
  • Joint development of UWB IP
  • Consulting
  • Other collaboration concepts possible
We open up the best of UWB technology to smart phones, cars and enable standalone integration in low power IoT devices (smart watches, wearables, tags, keyfobs, sensors)

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


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
