Information technology — Radio frequency identification for item management — Part 2: Interference rejection performance test method between an Interrogator as defined in ISO/IEC 18000-63 and a heterogeneous wireless system

This document specifies a test method to evaluate the interference rejection performance of UHF RFID interrogators covered by ISO/IEC 18000-63, and specifies the general requirements and test requirements of that test method. NOTE The interference rejection test method of this document is different to the one in ISO/IEC 18046-3:2020, 8.5. This document covers interference effects between the tags and a heterogeneous (diverse content) wireless system. ISO/IEC 18046-3 covers interference effect between tags and homogeneous (same content) wireless systems. This test method enables the comparison of the relative interference rejection performance among UHF RFID interrogators under a single wireless interference environment. In addition, this document can be used in a benchmarking test, according to requirements in a given application or service.

Introduction
Ultra-high-frequency (UHF) radio frequency identification (RFID) is a wireless technology that connects
billions of everyday items to the Internet of Things (IoT), enabling consumers and businesses to identify,
locate, authenticate and engage each item. IoT applications require a data connection between the
physical and digital world, and UHF RFID is the ideal technology to bridge these realms, with the ability
to bring low cost, unique identification to everyday items. Low-power wide-area networks (LoRaWAN)
operate at long read ranges of 2 km to 3 km. While LoRaWAN devices have a very slow data-transfer
rate, they are useful for transmitting sensor data. For example, LoRaWAN, WiFi-Halow (802.11ah),
Sigfox, NB-IoT, WB-IoT, and LTE-M are representative technologies.
The frequencies used by LoRaWAN systems differ by region and country, as do the frequency bands
designated for UHF RFID systems. In particular, LoRaWAN and RFID systems use different power levels
and heterogeneous protocols in shared frequency bands. They are susceptible to interference generated
by other wireless systems. This harsh signal propagation environment, combined with interference
from coexisting wireless technologies, can lead to a degradation of the systems performance or even
application failures.

1 Scope
This document specifies a test method to evaluate the interference rejection performance of UHF
RFID interrogators covered by ISO/IEC 18000-63, and specifies the general requirements and test
requirements of that test method.
NOTE The interference rejection test method of this document is different to the one in ISO/IEC 18046-3:2020,
8.5. This document covers interference effects between the tags and a heterogeneous (diverse content) wireless
system. ISO/IEC 18046-3 covers interference effect between tags and homogeneous (same content) wireless
systems.
This test method enables the comparison of the relative interference rejection performance among UHF
RFID interrogators under a single wireless interference environment. In addition, this document can be
used in a benchmarking test, according to requirements in a given application or service.
