The IoT is one of the global infrastructures for the information society, delivering advanced services by interconnecting things based on, existing and evolving, interoperable information and communication technologies. Such a global infrastructure can be achieved by use of multiple access technologies for different types of communication networks such as BAN, PAN, LAN, WLAN, LPWAN, FAN, MAN, WAN and Cellular networks. Conformance and interoperability tests not only for domains with single access technology but also for the integrated domains with multiple access technologies are required. The main goal of this Recommendation is to specify the testing framework for IoT to accommodate the tests for such integrated domains with multiple access technologies. Conformance and interoperability tests for domains served by single unified access technology have been taken into account by relevant SDOs and therefore are out of scope of this Recommendation. This Recommendation describes the types of the tests for the domains with multiple access technologies, and specifies the test procedures and the considerations correspond to the testing types.
