ISO/IEC 24769-2:2013 defines the test methods for determining the conformance of 2,4 GHz real-time locating system (RTLS) tags with the specifications given in the corresponding subclauses of ISO/IEC 24730-2, but does not apply to the testing of conformity with regulatory or similar requirements. The test methods require only that the mandatory functions, and any optional functions which are implemented, be verified. This may in appropriate circumstances be supplemented by further, application-specific functionality criteria that are not available to the general case. The RTLS tag conformance parameters included in ISO/IEC 24769-2:2013 include the mandatory direct sequence spread spectrum (DSSS) 2,4 GHz radio frequency beacon. It also includes the optional on-off keyed, frequency shift keyed (OOK/FSK) short-range radio frequency link and the optional magnetic air interface. Unless otherwise specified, the tests in ISO/IEC 24769-2:2013 apply exclusively to RTLS tags defined in ISO/IEC 24730-2.
Abstract
Overview
ISO/IEC 24769-2:2013 - Information technology - Real-time locating systems (RTLS) device conformance test methods - Part 2: Test methods for air interface communication at 2,4 GHz - defines standardized laboratory test methods to verify conformance of 2.4 GHz RTLS tags and related RF receivers to the air‑interface specifications in ISO/IEC 24730-2. It specifies how to measure mandatory and implemented optional functions (DSSS BPSK beacon, optional OOK/FSK short‑range link, optional magnetic interface) but does not address regulatory compliance.
Key topics and technical requirements
- Scope and applicability
- Tests apply to RTLS tags defined in ISO/IEC 24730-2 and to DSSS RF receivers and optional magnetic exciters.
- Regulatory testing is excluded.
- Test environment & tolerances
- Default conditions: 23 °C ± 3 °C, relative humidity 25–75 %.
- Default tolerance: +5 % on test equipment and method characteristics.
- DSSS (BPSK) transmission tests
- Message format: 152‑bit blink (with at least two sub‑blinks) and PN code verification (511 × 152 = 77,672 chips).
- Carrier frequency: 2 441.750 MHz ± 61 kHz; drift
