Future of Wireless Solutions and Security

This chapter discusses future views of wireless security, including the development of trends and the impact of key enablers such as Big Data. Related security threats and solutions are discussed, emphasizing the importance of balancing proper security mechanisms while providing fluent user experience and avoiding performance degradation even with extensive data transmission, which can be expected as the number of Internet of Things (IoT) devices grows. The chapter summarizes the evolution of sensor networks and their security. The main message for the industry is that the IoT devices need to include in‐built security solutions instead of relying solely on the protection mechanisms of the network infrastructure. The chapter introduces the mobile communications systems of 5th generation (5G) and beyond, including items under preparation for standardization and security challenges of future wireless technologies. The aim of the global 5G standard is to increase the data rate and speed up the response time.
