Wireless Communication for In-Action Data Streaming in Ski Jumping
Implement and test a robust wireless data link using BLE Coded PHY for real-time data streaming in ski jumping.
Keywords: Firmware design, Bluetooth Low Energy, Field evaluation
In ski jumping, low repetition rates of jumps limit effectiveness of training. Thus, increasing learning rate within every single
jump is key to success. A critical element of athlete training is motor learning, which has been shown to be accelerated by
feedback methods. Today, the coach’s training feedback is mainly based on video recordings.
They provide good insight into the whole jump, but only on a coarse level. Small imperfections cannot be revealed.
To improve trainer feedback, recorded data (foot’s center of pressure, ski angle, ski opening angle, …) need to be transmitted
directly from the jumping athlete to the coach’s tower. For this a reliable wireless communication with sufficient bandwidth
and range is needed. Bluetooth Low Energy Coded PHY is a suitable candidate for this task.
**Prerequisites (not all necessary)**
- Experience in C-programming with microcontrollers
- Experience in Python
- Experience with wireless communication (ideally BLE) is beneficial
- Basic Knowledge of circuit design
**Type of Work**
- 60 % Firmware development
- 20 % In-field evaluation
- 10 % Hardware evaluation and integration
- 10 % Data analysis and documentation

The main goal of this thesis is to implement and test a reliable Bluetooth Low Energy Coded PHY wireless communication
between an already existing sensor node and a gateway. Field measurements (even with real Ski jumpers) should evaluate
the performance of the developed system.
