ISO/IEC 24730-62:2013 PDF

Overview

ISO/IEC 24730-62:2013 specifies the High Rate Pulse Repetition Frequency (HRP) Ultra Wide Band (UWB) air interface for Real Time Locating Systems (RTLS). It defines the physical layer (PHY) modulation and the over‑the‑air message (Air Interface Protocol, AIP) needed for UWB-based RTLS. The standard is based on IEEE 802.15.4a UWB technology and targets systems that require high update rates and fine position resolution (for example, location accuracy within tens of centimetres and update intervals on the order of seconds).

Key Topics

• PHY modulation and signalling: HRP UWB using mean/peak pulse repetition frequencies (PRF) of 16 MHz or 64 MHz, and a hybrid of Burst Position Modulation (BPM) combined with Binary Phase-Shift Keying (BPSK) to support coherent receivers.
• Packet and frame structure: Definitions for PPDU/PSDU formats, preamble and PHY header (PHR), data fields, Forward Error Correction (FEC), and Frame Check Sequence (FCS).
• Timing and ranging: Timestamps, time units, antenna delay handling, and support for Time Difference of Arrival (TDOA) and two‑way ranging.
• Message types and AIP: One‑way "blink" messages for infrastructure TDOA, plus optional bidirectional data messages and two‑way ranging procedures.
• Operational modes and interoperability: A mandatory default mode for cross‑vendor interoperability plus optional features to adapt system behaviour.
• Normative references: Builds on IEEE 802.15.4a and ties to ISO/IEC 15963 (tag identifiers) and other ISO/IEC RTLS parts.

Applications

• Asset tracking and inventory management in warehouses, hospitals, manufacturing and logistics where centimetre-level positioning and frequent updates are required.
• Real‑time location systems (RTLS) using UWB air interface for indoor positioning, personnel safety, automated guided vehicles, and industrial IoT.
• Solutions requiring robust multilateration (TDOA) or two‑way ranging for high‑precision distance measurements.
• Target users: RTLS system architects, hardware (tag/reader) designers, firmware developers, integrators, and solution vendors implementing UWB-based tracking.
