Intercom, in the past is a mysterious veil of communication tools, the general public are generally from the film and television to know its magic function, can real-time wireless calls and is not subject to regional restriction, especially in the crime or war movies, the police siege bandits or military strategic command, moment also cannot leave the intercom security efficient scheduling command and convey instructions, even if the desolate desert mountains, also can talk freely!Now speaking of walkie-talkies, we are all very familiar with them, especially in construction engineering, transportation, hotel, supermarket, port, mining engineering, sports events and other industries.However, how the walkie-talkie "refined", few people know!The quality of a walkie-talkie communication depends on sound quality, battery life and communication distance.Good signal, clear sound quality, long battery life, long call distance, is often the majority of users most concerned about the elements, which directly related to the communication experience!So, walkie-talkie in the production research and development process what is particular about, in the raw materials, components and other aspects of what is required, in order to ensure each product excellent and excellent communication quality!

　　In the fuselage protection, the interphone has the super-high fuselage protection, the seismic resistance is more than 1.5 meters!The actual communication test shows that after 1.8 tons of vehicle crushing, the fuselage shell is still intact, all communication indicators are normal......Such superb performance, in the entire Chinese domestic walkie-talkie market is very rare, some test indicators even exceeded the international walkie-talkie brand!

　　Die casting is another important part of walkie-talkie, which can be divided into aluminum alloy die casting and common die casting.This part not only has the effect of fast heat dissipation, but also has the special function of shielding interference. Although it is not a high-tech part, its application or not has a great impact on the wireless communication of walkie-talkie!In order to save production costs, some manufacturers do not hesitate to apply low-quality die casting, or simply do not die casting, has achieved price advantage!Although such walkie-talkie price is cheap, but in practical use, it will cause a lot of communication barriers, such as the fuselage, communication interference and so on!The application of the best aluminum alloy die-casting in the market, not only heat dissipation effect is good, interference shielding is very outstanding, after the high intensity of the communication operation test, not only the body is not hot, but also completely shielding communication interference, communication effect is very satisfactory!

　　Dust-proof and water-proof is one of the most important test indexes of walkie-talkie.The interphone IP67 is dust-proof and water-proof industrial grade, realizing complete isolation of dust, and at the same time, the interphone can still talk freely in the water depth of more than 30 minutes below 1 meter, fully meeting the needs of all kinds of wind, frost, rain, snow, dust, haze and other harsh communication environment.In addition, walkie-talkie in speakers, vocoder, keys, batteries and other important components, also as always the application of industry-leading accessories, such as, beifeng walkie-talkie speakers, 2W audio power load, 72 hours of uninterrupted talk test;3W audio power load, 24 hours uninterrupted call test, sound quality has not changed any, still clear and pleasant.Such a high - intensity test is hard to imagine ordinary walkie-talkies.Although the sound quality also benefits from the application of the industry's top vocoder excellent decoding, but if there is no good speaker, no matter how good decoder can play their excellent effect!

Walkie-talkie function keys, especially PTT keys, in wireless communication work has a decisive role!Without PTT control, the walkie-talkie is basically dead (unless you have headphones and it also happens to support voice-activated calls), and you can't really be a walkie-talkie!Because PTT is frequently used in the communication of wireless walkie-talkie, it is also one of the most easily malfunctioning parts of ordinary walkie-talkie in the market.Due to manufacturing process and cost constraints, ordinary walkie-talkies are relatively weak in the test equipment, and the test standards are uneven, the quality can also be imagined, some machines even less than a month will break down......Walkie-talkie PTT and other core function keys, after up to 300 thousand times of strict testing, is 500 times per day of ultra-high frequency launch, can fully use more than 600 days, to ensure the stability of each information command send!

　　In terms of batteries, ultra-high quality battery cells are applied with intelligent protection board. The actual test shows that 80% of the battery power is still maintained after up to 500 cycles of charging, ensuring communication time!That is to say, even if we carry out a cycle of charging and discharging every day, it can be normally used for more than 18 months...After such frequent charging and discharging cycles, only 20% of the battery capacity is lost, and the battery can maintain 80% of the capacity for subsequent use.This is a nightmare for those of you who are refurbishing shoddy walkie-talkie batteries...   

　　After 36 years of rapid growth, many walkie-talkie brands have been born in China.Along with the rapid integration of the whole industry and the popularity of radio commercial civil market, the majority of users of the radio communication needs further improve, especially in the modern Internet technology and the rapid development of intelligent technology such as smart dress, for the development of traditional radio opened a new field, it is also of various performance indicators put forward higher requirements for radio!How to further develop core intelligent technology and improve product quality under the background of contemporary technology, combined with the industry opportunity of global interphone analog to digital transformation, has become the time challenge facing the majority of interphone businesses!
