Narrowband Internet-of-Things (NB-IoT) is a radio technology standard developed by 3GPP standard committee, targeting to enable a wide range of cellular devices and services for Low Power Wide Area (LPWA) networks. NB-IoT technology has the characteristics of wide coverage, multi connection, low power consumption and low cost. It is suitable for low speed or static internet of things (IoT) applications, such as intelligent meter reading, intelligent parking, intelligent agriculture, smart city (manhole cover, street lamp). The next generation release 15 NB-IoT standard considers the new features, such as small cell support, Time-division Duplexing (TDD) support, as well as further increased coverage, which are important to private network applications.
In this project, ASTRI plans to develop the 3GPP Release 15 Narrowband Internet of Things (NB-IoT) baseband solution to support massive low cost IoT applications. The project team will design and implement Rel15 NB-IoT base station base band reference design, including the link level NB-IoT simulation platform and the test infrastructure to verify standard requirements.
Several companies have shown a strong interest in collaborating with ASTRI to commercialize our NB-IoT technologies developed from this project. Initially engaged customers include: a small cell public and private network equipment provider, Anktion (a subsidiary of Fujian Sunnada) and a telecommunication test equipment vendor, Rohde&Schwarz (R&S). Other equipment vendors, such as HBFEC and H3C have also approached us for potential technology licensing from this project.
