Have you ever wondered, "What is the difference between IR (Infrared) and UHF(Ultra High Frequency) wireless systems" ? The critical difference between the two is whether the signals pass through the solid walls (*1) or not. IR systems send and receive "NON-through-wall signals" whereas UHF systems use "through-wall signals." (*1) IR wireless pass through transparent walls such as glass walls and windows.
Advantages of IR Wireless System
✓ Secure Communication Secure communication is assured with IR wireless system. It prevents signal jamming, which is a common problem when you use UHF wireless system. IR system is a great choice when you use it in conference/ class rooms where you want to keep the conversations confidential.
✓ No Interference Even if the same communication channel is used in adjoining rooms, no interference can be occurred. 1,000 conference systems can be operated simultaneously with no interference (technically no limitation).
Disadvantage of IR Wireless System
Infrared wireless system can be interfered by sun-lights and infrared noise from plasma displays.
