Simulate Bumblebee and Extend It to Support LE Coded PHY in BLE version 5

Abstract

Bumblebee is an innovative backscatter system that leverages productive Bluetooth Low Energy (BLE) carriers to generate ZigBee transmissions. It improves upon previous systems like FreeRider and Interscatter by eliminating restrictions on exciters and receivers, resulting in reduced deployment costs and increased throughput. To enable long-distance signal transmission, BLE version 5 introduces LE Coded PHY. However, the paper proposing Bumblebee only evaluates it with BLE version 4, which utilizes LE Uncoded PHY. In this paper, we initially simulate Bumblebee using MATLAB to assess its design. Subsequently, we extend Bumblebee to support LE Coded PHY in BLE version 5 and conduct experiments to verify its performance.
