Why haven’t walkie-talkies been eliminated by mobile phones? The answer is here

With the emergence of mobile phones and the continuous upgrading of smart functions, mobile phones have eliminated BB machines, game consoles, single navigation screens, etc., but our walkie-talkies have not been eliminated.

Isn’t it surprising that a walkie-talkie with a simple intercom function can survive the powerful attack of mobile phones to this day, and even function stably for a long time?

In fact, if you have a little in-depth understanding of walkie-talkies, you will know that this result is not surprising at all!

First of all, we need to know when we will use intercoms. Intercoms are mainly used in public security, civil aviation, transportation, water conservancy, railways, manufacturing, construction, services and other industries. They are used for communication and command and dispatch among group members to improve communication efficiency. and improve the ability to respond quickly to emergencies. As walkie-talkies enter the civilian market, people are increasingly using and understanding walkie-talkies when traveling and shopping.

Secondly, everyone should know that not all places have as good signal coverage as China, nor can mobile phones be used everywhere. If a mobile phone is to be used normally, there must be a mobile phone base station nearby. The mobile phone can communicate with the base station to ensure that the mobile phone call can proceed. If the mobile phone has no signal, then the mobile phone is basically a "brick". .

But walkie-talkies are different. As a radio device, a walkie-talkie does not need a base station or a network. Two walkie-talkies can communicate by adjusting to the same frequency.

Let me first tell you a few usage scenarios so that everyone can better feel the importance of walkie-talkies:

Special environment, no fear of calling

It’s the end of the month, and it’s time to take inventory. This time it’s your turn to go to the cold storage to take inventory. It’s not ready yet when you get off work, but you and your colleagues are at the end of the inventory. The supervisor calls out twice, is there anyone there? You didn’t hear it, and your colleagues also He didn't hear it, so no one expected that you two were imprisoned.

At this time, the mobile phone signal of the two of you disappeared directly. There was no signal, the phone could not be connected, and there was no mobile data. If anyone found out, you two would have been frozen into popsicles.

Fortunately, your colleague still had a walkie-talkie in his hand, so you two managed to hold on without panic at all, because the walkie-talkie can be used even in a closed environment, and immediately called the supervisor to bring someone to open the door.

In emergencies, walkie-talkies are more reliable

After making an appointment for a year, I finally got to meet up with my friends for a self-driving trip in the wild. Four families and four cars.

The vehicle was traveling on a winding mountain road, with valleys on one side and mountains on the other. It had just rained two days ago, and rocks would roll down accidentally.

Xiao Wang has the most experience and drives at the front. He is responsible for communicating with the entire convoy and reporting road conditions to the cars behind. The others follow the lead car.

The winding mountain road made everyone nervous. At this time, just after turning a big bend, a large rockfall suddenly appeared in the middle of the road. At the critical moment, you stepped on the brakes in time and the car stopped on the side of the road. It turned out that Xiao Wang assigned a walkie-talkie to everyone in advance and informed everyone about the rockfall immediately. If you use a mobile phone, by the time the call is answered, you may have hit a rockfall or gotten into an accident while panicking. The above are just a few scenarios. In general, even though mobile phones have long become an indispensable way of communication in everyone's daily life, walkie-talkies still have an irreplaceable position among workers in professional fields and under special circumstances.
