ISO/IEC 24769-62:2015 PDF

Overview

ISO/IEC 24769-62:2015 defines conformance test methods for Ultra Wide Band (UWB) Real Time Locating System (RTLS) tags that implement the high rate pulse repetition frequency (PRF) UWB air interface described in ISO/IEC 24730‑62. It specifies how to verify mandatory (and implemented optional) functions of RTLS tags and RF receivers against the air‑interface specifications. The standard covers laboratory test setups, required measurements, reporting content and measurement uncertainties, but does not replace regulatory conformity testing.

Key topics and requirements

• Scope: Applies to RTLS tags and RF receivers defined in ISO/IEC 24730‑62; excludes regulatory compliance tests.
• Test environment: Default laboratory conditions of 23 °C ± 3 °C and relative humidity 25–75 %.
• Default tolerance: 5 % tolerance on test equipment and procedure parameters unless otherwise specified.
• Noise-floor check: Spectrum analyzer acquisition for ≥1 minute; measured noise must be at least 60 dB below the expected tag amplitude at −16 dBm with tag at 1 m.
• UWB RF transmission tests:
  • Validate UWB modulation waveform, spectral mask (per ISO/IEC 24730‑62), and transmit power (calculated from received power; allowed ±2.0 dB vs. specified).
  • Transmitter timing: PRF chipping and operating channel centre accuracy ±20 ppm; timing measurements using 1 MHz RBW and 1 kHz VBW.
  • Verify message structure (preamble, SFD, PHR, payload) per ISO/IEC 24730‑62 for configured modes.
  • Typical test setup uses anechoic chamber, calibrated antenna, spectrum analyzer and high‑speed oscilloscope (examples cited in the document).
• Receiver tests:
  • Use a tag generator to exercise receiver modes and measure detection/decoding performance.
  • Report detection percentages and all measured data.
• Reporting: Test reports must include measured values, tag-to-antenna distance, post‑processing description and test equipment specification (including measurement uncertainty).

Applications and users

This standard is practical for:

• RTLS tag and reader manufacturers verifying conformance of UWB devices.
• Test laboratories developing accredited conformance test procedures.
• System integrators and quality engineers ensuring interoperability and predictable RTLS performance in asset management, inventory tracking, and indoor positioning solutions.
• R&D teams designing UWB RTLS hardware and firmware to meet international air‑interface requirements.
