What are the potential implications of 5G connectivity on the latency and reliability of power meter data streaming, and how might this impact the effectiveness of real-time training data analysis and feedback for cyclists? Specifically, can 5Gs lower latency and higher bandwidth support more seamless integration of power meter data with other training metrics, such as heart rate and cadence, to provide a more comprehensive picture of a riders performance? How might this, in turn, influence the development of more sophisticated training algorithms and AI-powered coaching tools? Furthermore, what are the potential security risks associated with transmitting sensitive training data over 5G networks, and how can cyclists and manufacturers mitigate these risks to protect athlete data?
