Domestic entrepreneurs interpret the difficulty of autonomous development of walkie-talkies

China's digital walkie-talkie industry is still in its infancy. Professional chips are lacking, standards are monopolized by foreign manufacturers, and the road to development is difficult. However, the domestic power represented by Hainengda, Kelilixin and Shikang did not give up because of this, which in turn reinforced their determination to independently innovate and break the monopoly.

Hai Nengda Chairman and President Chen Qingzhou: Seizing Customization Trends

Intercom technology is in the period of transformation from analog to digital rapid conversion. Chen Qingzhou, chairman and president of Hytera, summarizes its market changes in two aspects: First, the technical changes in the number of revolutions will significantly increase the technological threshold of radios, leading to The price of digital products is higher than simulation, but for the low-end market, the same problem exists. Since there are not many vendors providing chips, the products may enter the meager era of homogenous competition in the future; secondly, with the rapid development of the walkie-talkie market, Demand for professional communications users is also increasingly complex. The market is more subdivided and more customized products are preferred. Chen Ching-zhou pointed out: “These two major changes are challenges for Hynanta, but it is even more that Hytera is catching up with foreign competitors. The opportunity to consolidate the leading position of professional communications in China."

At present, the domestic walkie-talkie market mainly focuses on the production and sales of analog walkie-talkies and systems, and there are still distances from the internationally-adopted digital standards. At the same time, traditional analog clusters that are more frequently used domestically have low spectrum utilization, small system capacity, and business functions. Single problems, poor security and confidentiality, etc., and other issues of foreign intellectual property rights barriers are all serious problems facing the domestic walkie-talkie market.

It is in this context that Hilonda has achieved leadership in the field of walkie-talkie standards. "To achieve rapid development, we must make every effort in terms of product quality, R&D technical strength, marketing network, and customer service system, but the most critical thing is to continue to innovate." Chen Qingzhou pointed out the key to Hainengda's success. The figures can best explain the problem: Hainengda extracts 10% of its annual sales revenue for the research and development of new products, and more than 700 R&D teams account for 35% of the company's total number. Haineng’s walkie-talkie product performance has reached the international advanced level, has passed certification from more than 70 countries and regions, and is widely used in public safety, military, transportation, water conservancy, commerce, hotels, ports, ocean-going operations, and factories and mines. Various industries and fields. The reserve of technologies and capabilities, as well as innovative business models, have created a more obvious competitive advantage for Hyntech in China and even in the world. In 2010, Hytera completed the successful brand switching from "HYT" to "Hytera" and was fully prepared to better create an international brand. Kelixun Donghuasong, vice president of the company: occupy the standard high ground

Compared with analog walkie-talkies, digital walkie-talkies have the advantages of high spectrum utilization, easy management, and rich applications. From simulation to digital evolution, they become the current trend of the development of walkie-talkie technology.

For a long time, due to the small market size of private networks, the development of walkie-talkie technology is relatively backward, and the development of domestic digital walkie-talkies is still in its infancy. The reporter learned from the branch of the mainstream walkie talkie manufacturer in China that the domestic manufacturers have increased the research and development efforts of digital walkie-talkies. Kelixin has already been in the prototype development stage and it is expected that there will be products on the market next year. Whether or not standards and patents can be solved is the key to the development of the walkie-talkie industry in China. It is reported that there is no standard of independent intellectual property rights in the domestic walkie-talkie market. Dong Huasong said that if China cannot introduce its own standards, the development of digital walkie-talkies will likely fall into the mud of foreign patents, requiring constant payment of high royalties. Therefore, we hope that all domestic manufacturers will unite and introduce our own standards.

The biggest problem encountered in the development of digital walkie-talkies is the lack of professional chips. Deputy Chief Executive Officer of Tecco Dong Huasong told the reporter, “There is currently no professional chip for digital walkie-talkies on the market. We can only use a common chip, and then proceed with the development of protocol stacks, algorithms, and drivers.”

The main reason for the lack of professional chips is the small market demand. No company is willing to invest a lot of R&D capital. In contrast, technology is not a problem at all. After all, mobile chips have been used extensively in the last century. At present, as the intercom moves from analog to digital on a large scale, the demand for professional chips has greatly increased.

“Developing on a general-purpose chip is a waste of energy. If you use a professional chip, the solution is already integrated in the chip. We only need to develop the application. We hope that domestic companies can develop professional chips.” Dong Huasong is full of expectations for professional chips.

Shi Zhongming, President of Wuxi Shikang Communication Technology Co., Ltd.: Challenges the International Core Problem of "Lack of Core"

The digital walkie-talkie is still in its infancy in the world. As the core technology module of the communication system, the lack of dedicated chips with low power consumption and high performance is the main factor restricting the development of the digital walkie-talkie.

Wuxi Shikang Communication Technology Co., Ltd. is striving to break this situation by introducing a low-power and high-performance single-chip system integration chip, and at the same time completing signal modulation and demodulation, voice codec and all levels of communication protocols (L1-L3). Features. Shi Zhongming, president of Synergy, told reporters that in Nice, France in May this year, the intercoms designed by Schconner chips and the ICOM products of Japan have successfully achieved DPMR interoperability, and the sound quality is very good. This is the first cross-company of European digital walkie-talkie DPMR. Interoperability. “Originally adopting foreign chips, the prices of digital walkie-talkies are several thousand dollars, and analog walkie-talkies are several hundred dollars, so it is difficult for digital walkie-talkies to be widely promoted. Our goal is to eventually reduce the manufacturing cost of digital walkie-talkies to today’s analog walkie-talkies. The manufacturing cost is even lower, in particular, S&C has successfully developed single-chip digital walkie-talkie baseband solutions and high-efficiency RF power amplifiers (200MHz-1GHz), which can be widely used in walkie-talkies, non-central and Tetra cluster private networks, etc. Shi Zhongming also briefed reporters on Shikang’s future R&D goals.

As the civilian walkie-talkie occupies most of the walkie-talkie market, Shikang will develop the civilian (FDMA, frequency division) digital walkie-talkie chip first. Currently, it has passed the European test standard and its customers have entered the design and manufacturing stage. "Competition for the introduction of the TDMA (Time Division) digital trunking scheme in 2011 will enter the Tetra market in 2012." Shi Zhongming told the reporter that the goal of Schemcon in 2011 is to target the European and American FDMA market, "the market is expected to have a scale of nearly 10 million."

Standards and chips are the most fundamental part of the control industry chain. Only if we have the initiative from the perspective of standards and patents, can our country's interphone industry have the basic conditions for healthy development. No. 666 set a timetable for the number of walkie-talkie models. As the chairman of the China Digital Walkie-talkie Industry Alliance (DRA) chipset, Shi Zhongming is actively working with other members of the DRA to promote the development of China's digital walkie-talkie standards. He told reporters: "At present, according to China's digital walkie-talkie standard, DRA mainly discusses three aspects." First, the use of TDMA or FDMA access. This determines the design difficulty and cost of the RF transceiver. Second, what kind of speech codec technology is used. At present, China has two technologies, and Russia and the United States have one technology. Among them, AMBE+2 is the most widely used technology in the United States. It includes many digital walkie-talkies and satellite communications in Europe and America. DRA is considering preferred domestic technology. Applying this technology in large quantities to various environments also requires a lot of testing work. Currently, it is being tested and promoted. Third, it discusses how to significantly reduce the power consumption and cost of the chip.

In fact, in the formulation of standards, as one of the nine members, Shikang participated in the development of the European digital walkie-talkie standard DPMR for more than three years. The European standard DPMR was finalized in March 2009. Shi Kang has confidence in the number of walkie-talkie models that can be established by China in the near future to achieve the 666 document plan within five years. All is ready except for the opportunity.
