Operational excellence through passive RFID: Rapid deployment solutions for indoor localization

Abstract

The demand for indoor positioning has grown significantly due to applications that rely on location awareness in
spaces such as medical facilities, warehouses, and smart buildings. Unlike outdoor environments, where global
positioning system operates effectively, indoor positioning faces the challenges of signal blocking and multipath
effects common in enclosed areas. Current solutions such as Wi-Fi, Bluetooth, and Ultra-Wideband (UWB) provide
effective results, but they often involve high costs and complex install processes, especially in big settings. Given
these challenges, passive radio frequency identification (RFID) has become a viable choice for indoor positioning.
Not only the technology is cost-effective, but also eliminates the need of active power supply to its tags, making
efficiency increase. This paper is proposing a passive RFID-based positioning system which designed for rapid
deployment to solve signal interference, a common problem in the area with neighboring small spaces. We explore
the limitations of the current RFID system and propose simple strategies to ensure location accuracy with minimal
installation needs.
