Overview
ISO/IEC 24770-62:2015 - Information technology - Real-time locating system (RTLS) device performance test methods - Part 62: High rate pulse repetition frequency Ultra Wide Band (UWB) air interface - defines standardized test methods to measure the performance of UWB RTLS devices (tags and readers) that implement the ISO/IEC 24730-62 air interface. The standard focuses exclusively on the UWB radio link between tags and readers and is intended to support equipment selection and system evaluation. It does not cover regulatory compliance testing.
Key topics and technical requirements
- Scope and applicability: Tests apply to RTLS equipment defined in ISO/IEC 24730-62 and target the UWB tag-to-reader air interface.
- Performance parameters covered:
- Location accuracy - compares system-calculated positions to actual tag locations (tests confined to line-of-sight).
- Tag capacity - verifies the number of tag blinks per second the system can process.
- Location latency - measures time from tag transmission to availability of location information.
- Tag orientation - ensures orientation changes do not materially affect reported location.
- System range and packet error rates - characterizes link range and reliability between tags and readers.
- Test conditions:
- Tests should be carried out in environments representative of the intended application (indoors/outdoors, typical RF noise, temperature/humidity).
- A default tolerance of 5% applies to quantities unless otherwise specified.
- Tests assume sufficient logging to count packets received/sent (system logging recommended).
- Test suites included:
- System locate performance (setups such as four-reader corner configurations)
- Mandatory tag-to-reader air interface tests
- Optional two-way-ranging tests
- Statistical relevance and reporting requirements for results
Applications and practical value
- Use ISO/IEC 24770-62:2015 to objectively evaluate UWB RTLS performance for asset tracking, logistics, manufacturing, healthcare, and other location-aware applications.
- Helps procurement teams compare products on measurable metrics (accuracy, capacity, latency, range).
- Enables system integrators and designers to verify that selected tags/readers meet application-level requirements before deployment.
- Provides consistent test methods for test labs performing product validation or vendor claims verification.
Who should use this standard
- RTLS device manufacturers (tags and readers)
- System integrators and solution architects
- Test laboratories and quality assurance teams
- Procurement officers evaluating RTLS products
- Standards and compliance engineers focused on indoor/outdoor positioning
