Hey, this is Ameerah Mason from UK. I am a scientist. Recently, I have researched on radio communication. Wireless systems come with two main things; one is base and other is a headset. The base is connected to the phone line and headset communicates via the base with the help of radio frequency set. Though Two Way Radio Wireless Headset is expensive as compared to the wired ones, but they allow people to have liberty in their working place, even when having a phone call on the line.
