Scope
This International standard defines a test method to evaluate the interference rejection performance of interrogators covered by ISO/IEC 18000-63, and specifies the general requirements and test requirements. This test method makes it possible to compare the relative interference rejection performance among interrogators under a single wireless interference environment. In addition, this standard can be used in a benchmarking test according to requirements in a given application or service.
Purpose
This standard provides test procedures and method to evaluate the impact on interrogators as defined in ISO/IEC 18000-63 of interference generated by other wireless systems. 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. However, The Sub 1GHz Radios are recently becoming very popular for many IoT (Internet of Things) applications such as Smart city, Smart manufacturing, Smart logistic. Low-power wide-area networks (LoRaWan’s) operate at long read ranges of 2 to 3 kilometers. Although 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 may lead to a degradation of the performance or even application failures. To evaluate possible interference on UHF RFID systems, industrial stakeholders make a constructive discussion on how to overcome interference problems.
