Final answer:
Tactical hand-held radio transceivers, cell phones, satellite phones, and personal locator beacons (PLBs) are indeed devices used for electronic communication. They are essential for maintaining communication in a variety of circumstances, including emergency situations. It is important to use these devices responsibly to prevent interference with sensitive equipment.
Step-by-step explanation:
It is true that tactical hand-held radio transceivers, cell phones, satellite phones, and personal locator beacons (PLBs) are devices that can be used for electronic communication. These devices serve various purposes and are vital for ensuring constant communication, especially in situations where typical means of connection might not be available.
Cell phones, for example, have become ubiquitous in their use for day-to-day communication. These devices contain both a radio receiver and a weak radio transmitter, allowing them to connect to network towers, which ensures we can send and receive messages nearly instantaneously. This communication capability is exemplified when trying to find someone in a crowd - the ability to call or text greatly increases your chances of reconnecting.
In more specialized scenarios, such as remote areas or international travel, satellite phones become crucial as they do not rely on ground-based infrastructure. Personal locator beacons, on the other hand, are essential safety devices used in emergency situations to pinpoint your location to search and rescue teams. Tactical hand-held radios are often used by military, police, and emergency services due to their reliability and the availability of secure frequencies.
However, there are instances where these devices can interfere with other sensitive equipment. That's why we're sometimes asked to turn off our mobile phones or switch them to airplane mode on flights or in hospitals, where they could adversely affect navigation or medical apparatus.
The Wireless Telecommunications Bureau oversees the policies and programs that ensure these various types of communication technology functions properly, without interference, and in compliance with regulations set out by the FCC.
