Why does CAP prefer using radios instead of phones or the internet?

The preference for using radios, particularly in emergency situations, stems from their reliability in maintaining communication even when other systems may fail. Radios operate on different frequencies and are designed to function in various conditions that can disrupt phones or internet services, such as power outages, network congestion, or physical damage to infrastructure. This resilience is critical when immediate and effective communication is necessary, ensuring that important information can be exchanged without the concerns that might affect other technologies.

The other options, while discussing various aspects of technology, do not capture the essential reason for the preference for radios. For instance, the advancement of technology in radios does not inherently guarantee better performance than phones or internet-based communication. Similarly, while maintenance might be a consideration, it is not the primary factor influencing the choice in urgent situations. Lastly, longer battery life can be an advantage, but it does not address the operational reliability of radios during emergencies, which is the crux of the matter.
