Comprehensive Detailed Explanation with all Technology Specialist References:
Infrared (IR) wireless microphones are particularly useful in environments where security is crucial. Unlike RF (radio frequency) systems, IR systems use light waves within a specific room or area, which makes them more secure since the signal doesn’t pass through walls. This containment ensures that the transmission remains private and prevents eavesdropping from outside the room. IR systems are ideal for environments like corporate boardrooms or government facilities where sensitive information might be discussed.
While large auditoriums (Option A) may use IR systems, they are generally limited to line-of-sight and aren’t suitable for large spaces due to coverage limitations. Rooms with direct sunlight (Option B) and spaces with high-frequency fluorescent lights (Option D) can cause interference with IR signals, making them less reliable in these settings.
