UHF RFID Spectrum Detection Threshold of the Secondary User for CSI Certainty

Abstract

The leading focus of this paper is to right of entry using passport details of a passport holder through Ultra High-Frequency Radio Frequency Identification (UHF RFID) technology UHF RFID is a popular technique in recent days for the fifth-generation (5G) mobile technology. It’s a spectrum sharing technique known as cognitive radio technology. The Cognitive Interrogator Network (CIN) is a monitoring system for passport identification technology. In UHF RFID several funded user is known as the primary user and several free users is known as the secondary user is using CIN, a threshold is observed for the different primary user with varying number of antennas and the medium is detected.
