The latest advances to Ultra-Wideband are adding both enhanced security and higher ranging accuracy. With this free Rohde & Schwarz poster have all important details of the physical layer and positioning techniques right there on the wall; all the information you need is there at a glance in easy to read 4-color format.
The additions to IEEE 802.15.4. have improved Ultra-Wideband as a technology of choice for high-accuracy, high-speed, low-power position locating (ranging), ideal for hand-held devices from key fobs to mobile phones. The latest amendment 802.15.4z-2020 added improved positioning accuracy for High Rate Pulses (HRP), plus improved security with a 128-bit scrambled timestamp sequence (STS) key, as HRP ERDEV (Enhanced Ranging Devices).
Just check the poster for HRP ERDEV details:
- HRP RF properties; channel frequency allocation, power spectral density, and pulse properties.
- Physical layer frame configurations, plus details of the synchronization header (SHR) and the scrambled timestamp sequence (STS).
- Modulation schemes for both the backward-compatible base pulse repetition frequency (BPRF) and the new higher pulse repetition frequency (HPRF) physical layers.
- Techniques supported for time of flight measurements and phase difference measurements.
