Review Questions

• How does 5G technology enhance the capabilities of the Internet of Things (IoT) compared to previous generations?
  • 5G technology greatly enhances IoT capabilities by providing significantly faster data transfer speeds and the ability to connect a much larger number of devices simultaneously. While previous generations like 4G could support thousands of devices per square kilometer, 5G can support up to one million devices in the same area. This allows for more efficient communication between devices and enables applications such as smart homes, connected vehicles, and industrial automation to function more effectively.
• What are the implications of low latency in 5G networks for industries such as healthcare and transportation?
  • The low latency characteristic of 5G networks has profound implications for industries like healthcare and transportation. In healthcare, for instance, it allows for real-time remote surgeries where surgeons can operate on patients from miles away without delay. In transportation, it enables autonomous vehicles to communicate instantly with each other and their environment, enhancing safety and efficiency. This capability fundamentally transforms how these industries operate and interact with technology.
• Evaluate the potential challenges that may arise from the widespread implementation of 5G technology across urban environments.
  • The widespread implementation of 5G technology in urban environments presents several challenges that need to be addressed. These include substantial infrastructure investment required for small cell installations to support dense networks, potential cybersecurity risks as more devices connect through IoT, and regulatory hurdles regarding spectrum allocation and public health concerns related to increased radio frequency exposure. Additionally, ensuring equitable access to this advanced technology across different socioeconomic groups poses another significant challenge that must be tackled to avoid creating a digital divide.
