Entering the 5G era, why use walkie-talkies with mobile phones?
With the rapid development of high and new technology, many people feel that the basic functions of walkie-talkies are gradually being replaced by mobile phone applications or basic functions. In the past, there was the basic function of voice transmission by mobile phones based on the principle of walkie-talkies, and later there was the walkie-talkie APP promoted by Apple. . Most people think that no one is willing to pay for a product that has long been outdated.
But in fact, the walkie-talkie field is still developing rapidly. What makes it stand firm in this new era of fierce market competition where the fittest survives? Why do people still choose to buy walkie-talkies after mobile phones and other communication software have functions such as intercom and video? Today, I will talk to you about the reasons why the walkie-talkie can stand up.
The walkie-talkie technology first appeared in the turbulent 1920s. The English name of the walkie-talkie is twowayradio, such as: Motorola (Motorola) GP338 explosion-proof walkie-talkie. It is a kind of two-way mobile communication technology tool. You can make calls, and there is no call charge. It is mainly used in relatively stable and frequent calls. There are three types of walkie-talkies at this stage: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies.
The mobile phone uses the basic principles of the Internet. It requires the terminal device to send it to the operator’s Internet, use the cloud platform to transform and compile the program, and then connect to the operator’s network, and finally receive the information content of the terminal device. Any abnormality of one of these parties is likely to cause the transmission of information content to stop, that is, blockage on the network channel.
The walkie-talkie is much simpler, while the wireless intercom is much simpler. From terminal equipment to terminal equipment, or terminal equipment using relay and then to terminal equipment, the relatively simple system reliability is much higher!
The walkie-talkie can complete real-time communication, and the wireless walkie-talkie can easily respond. Just the sender taps the PTT button to send his own voice and the receiver can listen to it immediately. When the sender releases the PTT button to send, the receiver He has already finished listening quickly.
The mobile phone is much worse on this. Assuming that the other party sends a 15-second voice, the sender needs 15 seconds to record and then consumes time to transmit on the Internet. In the end, the recipient needs 15 seconds. You can listen to it. The whole process will take more than a minute or more to complete, but the wireless walkie-talkie only takes 15 seconds to achieve this effect. Although this is not a big difference in simple calls on weekdays, it can become a fatal flaw if you work under high intensity.
In general, we can understand that even though mobile phones have long become an indispensable way of communication for everyone in daily life, in the eyes of professional staff and a small number of radio enthusiasts, walkie-talkies still have an irreplaceable position. What's more, the mobile phone sends and receives according to the mobile network signal. Without the network, the mobile phone is a brick, and the walkie-talkie sends and receives according to its own equipment. You can call without all the Internet support, and there is no call charge formation, applicable Places that frequently call.
