Episode notes
Bluetooth Keeps Evolving Into New Domains
- Bluetooth started as a consumer wire-replacement but keeps adding features that unlock new use cases beyond audio.
- Those periodic feature updates drive expansion into smart sensors, locationing, industrial, and automotive domains.
Bluetooth Very Long Range Capabilities
- Very long range mode can reach up to five kilometers line-of-sight using coded PHY and an external power amplifier.
- Practical indoor use covers large warehouses or whole-office coverage enabling single-hop connectivity for robots and sensors.
Prefer Bluetooth For Low-Throughput, Long-Range Needs
- Choose Bluetooth over Wi‑Fi when throughput needs are low and range or ecosystem matters more than high data rates.
- Use coded PHY modes for low-bit-rate telemetry or switch control to maximize range and reliability.
