The Russian-Ukrainian war tells you that walkie-talkies cannot be replaced by mobile phones

According to media reports, since the outbreak of the Russian-Ukrainian war, people in many places in Ukraine are actively preparing special survival materials, such as guns, food, gasoline and even walkie-talkies.

Kyiv resident Ruslan Rokhov legally bought some weapons for personal and family defense two years ago. When tensions on the Ukrainian border escalated again, Rokhov, to prepare for possible emergencies and shortages, purchased portable gasoline containers with sprinklers to self-feed the car when the gas station ran out of gas. come on. At the same time, he also bought two wireless walkie-talkies, which can help him contact his relatives nearly 15 kilometers away if the mobile phone network is damaged. "Mobility is important, but so is staying connected to coordinate operations," Rohoff said.

It can be seen from this that in the event of a war or natural disaster, a walkie-talkie that can be contacted at any time is very important, so it is impossible for a walkie-talkie to be replaced by a mobile phone. For specific reasons, I have listed the following six points:

The first is convenience: within an organization, as long as the frequency of the walkie-talkie is the same, any walkie-talkie calls can be received by other walkie-talkies, realizing mutual intercom between one person and many people; To call multiple people, it needs to be implemented by software, network, etc. If you don't use these, if there are other calls in the middle of the call, the other party will have to wait.

The second is fast: information dissemination is convenient and fast, which is convenient for internal command and dispatch of the organization and close contact. When encountering the Russian-Ukrainian war and the eruption of the Tonga volcano, once there is a problem with the base station, the mobile phone is very unreliable.

The third is economy: there is no call fee for using the walkie-talkie; for people who have frequent internal calls, it can reduce costs and save expenses. Although the tariffs of the three major domestic operators are now reduced, calls and traffic still have to be bought with real money.

The fourth is freedom: the walkie-talkie does not need network support, and the keystroke can be used to talk freely, which plays a great role in tourism or engineering work in the suburbs outside the city. The mobile phone needs the signal of the station, and it is located in a place where the signal is not good, often in a sparsely populated area, and the mobile phone can only be an iPod.

The fifth is battery life: the application of the walkie-talkie is specific, and the battery life is long. However, if you want to use the current large-screen mobile phone to the fullest, are you worried without bringing a few charging treasures?

The sixth is durability: the walkie-talkie is strong and durable, and it can be drop-proof and waterproof for a few hundred dollars. If you change to a mobile phone, it is estimated that you will need to buy or repair it again.
