Description
Bluetooth is the umbrella radio-protocol family operating in the 2.4 GHz ISM band. In thesis-relevant work the relevant subset is ble (Bluetooth Low Energy), which is the version actually deployed for indoor localization, beacons, and the BLE-calibration architecture proposed in the thesis. This entry exists to canonicalise generic mentions and the awkward BTLE alias that some early-2010s papers use ambiguously between Classic and LE.
Specs / capabilities
- 2.4 GHz ISM band (2.402-2.480 GHz)
- Adaptive Frequency Hopping (AFH)
- Two physical layers: Classic BR/EDR (legacy, voice / streaming) and BLE (low-power, advertisement-driven)
- Mesh, GATT, GAP profiles defined per generation
Tooling
- See ble for sensing-relevant tooling
Used by (papers)
- Generic positioning term; resolve to ble for indoor sensing context
