The use of walkie-talkies has become very common nowadays. The common walkie-talkies on the market are also diverse in terms of appearance and function, and there is a wide range of choices for everyone. Of course, the prices of walkie-talkies of different models and fields range from tens to hundreds of high and low. So what factors determine the price of walkie-talkies? Let's look at the reasons for the large price difference of walkie-talkies from different aspects.
1. The material of the walkie-talkie
The materials of walkie-talkies at different prices are different. Similarly, when we are purchasing walkie-talkies, we can also choose the walkie-talkie suitable for our own use according to the different environment. The high-priced walkie-talkies we usually see are made of high-quality PC, PC+ABS plastic materials and metal materials. The walkie-talkies of this material generally have the functions of abrasion resistance, drop resistance, waterproof, and anti-aging. Relatively speaking, the material of the low-priced walkie-talkie can also meet the needs of daily use, but the ability to deal with special environments will be inferior. Therefore, we must consider the environment in which we use the walkie-talkie while purchasing. In special environments such as construction sites, engineering sites, outdoor adventures, etc., we had better choose some walkie-talkies with better materials.
2. Process design
In addition to good materials, process design is also an important part of the walkie-talkie. If there is only a good material and the craftsmanship is not fine enough, the quality of the walkie-talkie will be greatly reduced.
Users often only pay attention to the changes in the external material of the walkie-talkie, but ignore the importance of internal design. For example: the circuit of a low-cost walkie-talkie does not have any shielding protection measures, and all the lines will be exposed to the outside, and the lines are easily damaged when they are hit. The high-priced walkie-talkies will adopt a closed protection method, which can protect the circuit well when encountering external forces.
There are also differences in accessories. Take the battery fixing method as an example. Low-priced walkie-talkies use glue filling to fix the battery, while some high-priced walkie-talkies choose a non-injected rubber pad for battery fixing, and the battery and the body are realized. For a perfect fit. At the same time, the circuit board of the expensive walkie-talkie battery adopts a flexible design, which can effectively protect the battery.
3. Performance configuration
Call quality is an important reference factor that determines the performance of a walkie-talkie. The high-performance walkie-talkie has high sensitivity, good call sound quality and certain anti-interference ability. The high-performance walkie-talkie adopts speech compression and coding technology that can be recognized according to the basic characteristics of human language, and has a strong ability to suppress environmental noise, and can receive clear speech even in a very noisy environment.
In terms of communication channels, there are more expensive walkie-talkies than ordinary walkie-talkies, and most of them are equipped with a mute code function. The mute code is designed in the message through a digital circuit and added to the message sent by the walkie-talkie. Identification code, each channel and one code in all allowed code groups can form a call. For example, 20 channels and 38 mute codes can provide 760 (20×38) call combinations, which means that within a radius of the effective call distance, up to 760 sets of walkie-talkies can talk to each other without interfering with each other.
Stability is essential for walkie-talkies. Walkie-talkies with high stability can ensure normal use in special environments, while walkie-talkies with insufficient stability can easily lose their communication function in harsh environments. How to judge the stability of the walkie-talkie?
One way to judge the stability of the walkie-talkie is to see whether internal and external tests have been carried out. All walkie-talkies have to undergo various routine tests without commissions for model approval. Some walkie-talkies are also subject to 11 US military standard tests, and some have also implemented strict internal tests, such as the industry’s famous five-year accelerated aging test.
5. Talking distance
The normal barrier-free use of ordinary walkie-talkies can reach 5-10 kilometers, but the actual environment causes 2-5 kilometers. In the case of basements and other environments with severe shielding, repeaters and omnidirectional antennas are required to complete signal coverage. But walkie-talkies of different price points also have a certain gap in this regard.
The higher-priced walkie-talkies are equipped with high-quality parts, so on the premise of ensuring quality, the call distance can be better than low-priced walkie-talkies. Of course, this is not absolute, and it has a lot to do with the environment in which it is used. In the same environment, the longer communication distance is often the better performance product.
There are many types of walkie-talkies, roughly professional walkie-talkies, commercial walkie-talkies, and civilian walkie-talkies. Professional walkie-talkie refers to a walkie-talkie with a transmission power of 4-5W and a frequency range of 136-174MHz or 400-480MHz; a commercial walkie-talkie refers to a walkie-talkie with a transmission power of 0.5-4W and a frequency range of 400-480MHz; a civilian walkie-talkie refers to a transmission power It is a walkie-talkie with 0.5W not more than 1W and a frequency range of 409MHz.
Generally, the high-priced walkie-talkies are professional walkie-talkies and commercial walkie-talkies. The power of these two walkie-talkies is about 5W, so their power is much larger than that of civilian use, and the natural talk distance will be longer than that of civilian walkie-talkies. Therefore, high-priced walkie-talkies are different from low-priced walkie-talkies in terms of power.
The above are the major differences between the walkie-talkies of different price points we have summarized. Of course, there must be other differences, so I won't repeat them here. Because of these differences, the price gap of walkie-talkies is obvious, so when we buy, we must think about the environment and purpose of using the walkie-talkie, so that we can better choose the walkie-talkie that suits us.
