Software-defined radio implementation of UHF RFID tags in 5G Internet of things application

摘要

The current and projected rapid increase in usage of the radio frequency identification (RFID) tags will yield new uses and applications in an Internet of things (IoT) environment. This chapter will discuss the implementation of software-defined radio (SDR) to aggregate, analytically process, and efficiently transmit data from RFID tags through a satellite backhaul solution. In the infrastructure proposed below, the first layer SDR aggregates RFID data at a tower level, the second layer SDR aggregates tower data at a low Earth orbit (LEO) satellite level, and then this aggregated data are backhauled to the gateway for the third layer SDR processing and data analytics. This chapter will discuss the RFID/SDR current and future capabilities, SDR design trades, RFID/ SDR system prototype test results, and satellite implementation scenarios.
