Mobile phones are developing at an astonishing speed. There are an endless stream of mobile phones with different appearances, different networks and functions, and their prices are also terribly high. But mobile phones have the Achilles’ heel. If there is no nearby cellular tower network, they will be completely useless.
However, walkie talkie, this kind of equipment can make wireless communication where the phone crashes.
Walkie-talkies are battery-powered transceivers, which means they can both send and receive radio messages. Unlike telephones, walkie-talkies use a push-to-talk (PTT) system-you must press a button to speak, and then you must release the button to hear the sound from other devices.
Compared with mobile phones, there is no need to remember the phone number and then dial the phone number, so the walkie-talkie is fast and easy to use. Most importantly, they are not dependent and do not need to spend phone bills. Therefore, when the cellular network fails during natural disasters or power outages, the two way radio can still work. They are mainly designed for short-distance communication, in which a group of people are only a few miles away from each other.
Companies use walkie-talkies so that employees can effectively chat in and around indoor and outdoor structures. Wilderness lovers carry walkie-talkies so they can keep in touch during hiking or hunting trips. Even baby monitors use one-way intercom technology, so you can know if your child is sleeping quietly or making noise.
It is no exaggeration to say that walkie-talkies have always been an important tool in our lives, and even will always exist and develop. If you haven’t used it yet, you might as well buy a pair and have a try. I believe you will fall in love with it.
