Which of the following statements is true?

The statement regarding the trade-off between mobility range and data speed in different technologies is accurate because it highlights a fundamental aspect of wireless communication. This principle is evident in many technologies such as Wi-Fi, Bluetooth, and cellular networks.

For instance, Wi-Fi operates at higher frequencies, which can provide faster data rates but typically has a shorter range. In contrast, technologies like cellular networks may use lower frequencies, allowing for greater range but generally at lower data speeds. This trade-off occurs due to the physics of radio waves and how they propagate through the environment.

Understanding this trade-off is crucial for network design and application deployment, as it helps in selecting the appropriate technology for a specific use case depending on whether speed or coverage is more critical.
