Prospects and challenges of Bluetooth backscatters system

Abstract

Bluetooth backscatter systems, as a crucial technology for low-power communication in the Internet of Things (IoT), have witnessed remarkable development in recent years. This article comprehensively analyzes multiple related papers, including the latest advancements in RF-Transformer and B2Loc systems, summarizes their research progress, challenges faced, and classification, and explores the application prospects and future development directions of such systems. Bluetooth backscatter systems have achieved significant results in terms of compatibility with commercial devices, improvement of communication reliability, and increase in throughput. However, they still face challenges in areas such as communication range, anti-interference ability, and hardware costs. In the future, with continuous technological innovation exemplified by breakthroughs in unified hardware abstraction and decimeter-level localization, Bluetooth backscatter systems are expected to play a more significant role in the IoT field.
