Exploring the latest Bluetooth® innovations
summary
Bluetooth announces two concrete advances: Channel Sounding adds secure distance measurement with a simple round‑trip mode giving 1–2 m roundtrip accuracy and a phase mode over up to 72 channels giving 10–20 cm phase accuracy, plus relay/replay/phase/time protections and early phone support (Google Pixel 10). Periodic Advertising with Responses (PAwR) creates synchronized, ultra‑low‑power star nets for electronic shelf labels with group slots, up to 255 devices per group, 128 groups and real deployments around ~7,000 nodes per AP.
