Integrated Access Backhaul Node supporting 5G and IoT Access

摘要

BHARATNET, the world's largest rural broadband project, aims to provide broadband connectivity to 2.5 lakhs gram panchayats across India. In chaining with BHARATNET OFC installation, FCC has created a runway for millimeter-wave researchers to launch 5G technologies with fiber-fast capabilities to reach broadband to end home users. The IAB technology is further formulated and standardized by 3GPP in Release 16 and 17 for the realization of FCC's creation of the use of millimeter-wave for small cell deployment. Full duplex (FD) technology is the promising technology for IAB with improved capacity but at the cost of Self Interference (SI). SI needs to be cancelled to improve system performance and reception of Signal of Interest (SOI). Dynamic spectrum sharing (DSS) is also helping a lot for improving system performance. The authors are engaged in development of 28 GHz IAB communication system with FDD mode and FD Mode.
