At present, there are countless brands and models of walkie-talkies, and prices vary greatly. When we need to buy a walkie-talkie, price is often an unavoidable factor. So, what is the difference between walkie-talkies of different prices?
Material, the cornerstone of quality
For many veterans in the industry, putting together walkie-talkies of different prices can usually tell at a glance who is higher, because the difference in body material is particularly obvious. The fuselages of high-priced walkie-talkies are mostly made of high-quality PC, PC+ABS plastic materials and metal materials. The walkie-talkies of this material generally have the functions of wear resistance, drop resistance, waterproof, and anti-aging. The appearance is also very eye-catching and the price is low. Relatively speaking, the material of the one-point walkie-talkie can also meet the daily use needs, but the ability to deal with special environments will be inferior. At the same time, walkie-talkies of different attributes have different requirements for materials. Commercial phones are small and portable, and need to be light and thin. Professional phones are durable and require harsh and uncompromising quality. 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.
Craftsmanship, more exquisite inside
The same cabbage is not necessarily made into boiled cabbage for a state banquet. The material is like ingredients. 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. Good design and workmanship will greatly improve the overall quality. Users often only pay attention to the changes in the external material of the walkie-talkie, but ignore the importance of internal design. The circuits of high-priced walkie-talkies are usually closed and protected, which not only protects the circuit integrity, but also shields radiation, while the circuits of low-priced walkie-talkies are all exposed. Once bumped or dropped, it is easy to cause damage. 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 high-priced batteries use glue-free rubber pads to fix the battery and the body to achieve a perfect artwork. fit. At the same time, the circuit board of the high-priced walkie-talkie battery provides more safety guarantees such as flexible circuit boards and insulator protection, which can effectively protect the battery.
Performance, you get what you pay for
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. Compared to walkie-talkies with a slightly lower price, high-priced walkie-talkies may have more abundant functions. Some are equipped with Bluetooth function, so that when we are not suitable for handheld walkie-talkies, such as riding, we can receive information through Bluetooth headsets without delaying calls at any time. Some high-priced walkie-talkies are also equipped with radios and flashlights. When we use them outdoors, we don’t have to worry about loneliness and darkness, and they are more convenient to use.
Reliable, never lose the chain at critical moments
The stability of walkie-talkies, especially those used in key departments/posts, is very important. Walkie-talkies with high stability can ensure normal use in special environments, while walkie-talkies with insufficient stability can easily lose communication functions in harsh environments. How to judge the stability of the walkie-talkie? If you don't want to hold a "brick" after encountering a harsh environment, a targeted design and rigorously tested walkie-talkie will be a better choice, which will ensure the communication quality of users in various environments. Industry standard testing is the touchstone of stability and reliability. All walkie-talkies must undergo various routine tests without commissions for model approval. Some walkie-talkies are also subject to 11 US military standard tests, and some have implemented strict internal Tests, such as the well-known five-year accelerated aging test in the industry.
Brand is a promise and a service
Brand originates from continuously improving product quality and user reputation. Brand means greater R&D investment and fine production of enterprises. Brand guarantees users' value-for-money return with a higher level of redundancy. Choosing different brands of walkie-talkies also determines the different services they enjoy. Classic brands often focus on the value of users, provide innovative functions and comprehensive services to ensure the full life cycle of the equipment, and respond to user needs.
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 high-priced walkie-talkies are equipped with high-quality parts, so under the premise of ensuring quality, the call distance can also be better than low-priced walkie-talkies. Of course, this is not absolute, and it has a lot to do with the environment of use. In the same environment, the longer the 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 the 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.
