LENOVO MAKE N7 WALKIE TALKIE walkie talkies look like a handheld, screen-less device, and work like radios. They can communicate wirelessly between one another on a single, shared channel, also called a frequency band. Each walkie talkie is powered by a battery and contains a transmitter as well as a receiver. The antenna at the top of the units transmits the radio waves between the devices.
The loudspeaker on the front of the device typically also servces as a microphone, and there is a button you can press to talk. When you first turn it on, you probably won’t hear anything but static until you press the push-to-talk button and the other person with the second device replies.
