Supervisors:
Prof. Dr.-Ing. Norbert When
Dipl.-Ing. Sebastian Wille Project work What is BLE? Bluetooth 4.0

Bluetooth Low Energy

Bluetooth High Speed Bluetooth enhanced its communication protocol to a state of the art low power technology.
BLE devices = Smart Devices BLE State of the art BLE power reduction technique - Reduce the the Radio activity
- 20mA max current peaks
- LOW Idle power
- SMALL chip packages
- FAST wake-up time Indoor positioning state of the art Pebble watch Myo Wristband Nokia HAIP 9solutions IPCS Key fob with nRF8001 Philips InRange Key fob TI key fob with CC2540 Standalone Arduino compatible BLE development kit BT classic vs
BLE Market research – BLE modules Market research – Turnkey modules BLE Stack Proximity analysis Triangulation and trilateration techniques :
- Time of arrival/Time difference of arrival (ToA/TDoA)
- Angle of Arrival (AoA)
- RSSI: received value is inversely proportional to the square of the distance; implementation is practical and low cost APPLICATION PROCESSOR RESEARCH HW Architecture FW
Behaviour SW
Architecture IMPLEMENTATION Functional description Outlook Master implementation:
- on Android emulator
- on Windows 8 machine
