摘要:Recent advances in Cross-Technology Communication (CTC) have improved efficient coexistence and collaboration among heterogeneous wireless devices (e.g., WiFi, ZigBee, and Bluetooth) operating in the same ISM band. However, until now the effectiveness of existing CTCs, which rely on packet-level modulation, is limited due to their low throughput (e.g., tens of bps). This talk introduces our recent breakthrough towards high- throughput CTC via physical-level emulation. Our technique uses a high-speed wireless radio (e.g., WiFi OFDM) to emulate the desired signals of a low-power radio (e.g., ZigBee) without any hardware and firmware modification - a feature allowing zero-cost fast deployment on existing WiFi infrastructure. Our technique, call WEBee, achieves over 10,000x speed improvement over the start of the art. Building upon WEBee, researchers can further develop cross-technology services that reach beyond what individual technology can accomplish.
