Abstract

This research paper explores how wireless communication has played a key role in transforming healthcare and bringing in a new era of personalized, linked, and data-driven medical services. With the proliferation of wireless healthcare applications, ensuring the security and privacy of sensitive medical data has become paramount. We discuss the potential of blockchain technology, to address challenges and to secure next-generation wireless healthcare. We have elaborated how blockchain’s core characteristics, such as immutability and decentralization, can create a secure and transparent environment for sharing and storing medical data. Additionally, this paper examines how emerging technologies, like secure communication protocols and Homomorphic encryption, can be integrated with blockchain in safeguarding medical data during transmission and improving overall connectivity in healthcare environments. Furthermore, we discuss the challenges and opportunities associated with implementing blockchain technology in real-world healthcare scenarios. By employing blockchain and physical layer security techniques, healthcare providers can mitigate security risks, preserve patient privacy, and facilitate seamless connectivity, thereby fostering trust and reliability in wireless healthcare systems. Finally this paper highlights the pivotal role of wireless technology in fostering a new era of healthcare that is more patient-centric, efficient, and informed by data-driven insights.
