The revolution of computer model of talkbacking urges the Private Network to subdivide The chip is a competition key
The appearance of the digitized intercommunication telephone set has offered the new development opportunity to manufacturer, in the chip in the competitive key of the cost of market of intercommunication telephone set in the future.
"We will not approve again to imitating the intercommunication telephone set in the future, and will not license again either. As to 450MHz-470MHz frequency band, have already incorporated into and uses for mobile communication according to the regulation at present, the State Radio Management Commission will not examine and approve the communication project on this frequency band in principle. Meanwhile, we will also issue relevantly and supplement the file in 2008, will come to further improve. Also need relevant expert and enterprise to canvass together now, make the intercommunication telephone set to transfer from simulation to a digitized time table together. " Recently,Ministry of Information Industry radio administration Jian Li division chief in "on the first intercommunication telephone set digital employ with at development forum " Call upon relevant expert and enterprise to make the commercial time table of the digital intercommunication telephone set as soon as possible. Can predict digital intercommunication telephone set era remote no longer already from us.
The mould revolution offers new machine on the market to manufacturer
"The business is so more difficult as to do! " This sentence nearly met the pet phrase when talking as intercommunication telephone set trade bosses. A worried one of intercommunication telephone set bosses is not that the space of market is smaller and smaller, in fact the market of Chinese intercommunication telephone set behaves very actively in recent years, the sales volume of many local markets is increasing, but because of the reducing of the profit, enterprises have not got the due income.
With the development of wireless communication skill, people have higher requirement for, spectral resources will be in more short too, and the digital intercommunication telephone set will rely on spectral high utilization factor and strong data communication function, having offered a kind of brand-new choice to user, because the digital intercommunication telephone set is still in the previous market at the same time, profit great, therefore contain the huge market potential. According to radio administration division chief Li Jian's words, the development of the digital intercommunication telephone set industry has already mentioned the agenda came up, meanwhile, the digital intercommunication telephone set correlation technique becomes more and more ripe too.
Vice President of Shenzhen of Tsing-Hua University graduate school Lin XiaoKang says when being interviewed by " China's electronic newspaper " reporter: "The digital intercommunication telephone set is not its digitized coding technique and data transmitting capacity to the simple substitution which imitates the intercommunication telephone set, will help users to boost productivity more effectively. The Chinese pronunciation encoding technique has already reached the international most advanced level at present, the pronunciation is checked and approved degree there is no difficulty in technology yet. After the standard formulation of the concrete products comes out, it is commercial that can realize the digital intercommunication telephone set in two years when believing. "
Come from gold bee's communicating former chief engineer Jiang RuiQing of the company has full confidence in market of digital intercommunication telephone set of future too. According to the introduction of Jiang RuiQing, because has not controlled key technology, the manufacturing industry of the hand machine of China originally fights on market of the low-price, low profit, just begin to move towards the advanced market after knowing key technology, the profit is thereupon rise too, so talkbacked the revolution of computer model brought the new development opportunity to Chinese manufacturing industry. It is that 50 million is multiplex that China imitates the intercommunication telephone set owning amount at present, the intercommunication telephone set purchased newly every year is 2 million, if realize the simulation of the intercommunication telephone set is transferred to digitization, it is only a market of tens of billion yuan in five years. If China communication manufacture industry catches this opportunity of the mould revolution of domain of professional mobile communication, undoubtedly catch another good opportunity that the communication manufacture industry develops.
It becomes the watershed that the market moves towards the number of users of sectionalization
A lot of trades in the society of intercommunication telephone set are widely used, so the market of intercommunication telephone set is a diversified market. Different trades, different work environment, different working occasions, different requirements need different intercommunication telephone sets. With the intersection of intercommunication telephone set and increase of demand, user's requirement for intercommunication telephone set products appear old difference. Its diversity has determined the diversity of the variety of the intercommunication telephone set too, the last kind of model obviously can't already meet demands of user to suit the use of many trades, this has offered the foundation for subdividing the market in the producer too.
As far as staff reporter know, the communication field of Private Network which China stipulates mainly has 4 items at present: 1.400MHz public intercommunication telephone set, do not need to apply for assigned frequency, does not need to handle the license of radio station, do not need to pay the occupancy of the frequency, for ordinary people to choose and converse and use arbitrarily at short range. 2.150MHz, 400MHz professional frequency modulation machine, need to apply for assigned frequency, handle the license of radio station, pay the occupancy of the frequency, for unit viewing distance to converse and use. 3.900MHz centerless multi channel address communication system, do not need to apply for assigned frequency, but need to apply for the assignment number, need to handle the license, need to pay the occupancy of the frequency, used as group's user's small-scale network connection. 4.35MHz, 800MHz digital trunk system mobile communiation system, are for the country, area or large-scale network connection of specialized department to use by assigned frequency. After the digitized intercommunication telephone set is introduced to the market, offer a kind of diversified choice to user.
Develop with moving the information-based industry, the market of Private Network still faces the competition from mobile service of public network. China Mobile and CHINAUNICOM have introduced enterprise's information-based business solution in all parts in the past two years, and the most overhanging bright spot is PTT (a key is called out) among them Business. This business and traditional intercommunication telephone set are used and is nearly as good as, does not just have unique user's priority and high-reliability confidentiality of a communication system of Private Network. But because move the operator and have coverage rate of the network widely, the signal is good, transport and link the ripe co dominant of the mode in low cost of the network and business, the impact to field of Private Network can't be ignored either.
Communication Deputy Director of Committee of Experts Lu JinHua's introduction that the credit of communicating according to the Chinese institute of electronics will be colonial, no technology can meet the requirement of all markets and all users, every user can be according to the need that its need and budget situation are equilibrated one's own. Trunking and regular intercommunication telephone set will coexist within quite long time. Choose the group system to be still a regular intercommunication telephone set, user's quantity is a key. The quantity of user holding in each signal channel of group system is more than regular systems, in the tense area of the frequency, choose to relieve the contradiction that user's quantity increases in trunking.
Produce and grind and separate and develop the competition core in the chip
Difference market demand brings the difference products too. According to the introduction of relevant expert, it is both worried and glad to intercommunication telephone set trade the past 2007 years. First of all, the whole sales volume of the intercommunication telephone set presents the anabatic trend, but the growth of the profit has not presented linear growth with the sales volume. Second, the products are more and more diversified, this mainly behaves in such aspects as such as the brand, quality, price and service, the intersection of brand and consciousness of customer strengthen too at the same time, previous low price machine large and competent in the city, but quality range, has influenced the customer's purchase confidence.
The director of graduate school ASIC research center of Shenzhen of Tsing-Hua University represent to " China's electronic newspaper " reporter right wealth yuan, on the market of intercommunication telephone set, the price of the top-grade machine of a gleam of brand represented by Motorola is generally about 5000 yuan, and the middle-and-low grade machine glides the range bigger in recent years. Basic identical importing machine of Japan of a function (the middle-and-low grade machine) Each one of current price on market was about 1800 yuan 10 years ago, it is about 1200 yuans but can only be sold for now, its fall is about the amount of 30%. The low-grade machine price disparity is larger, the identical machine of a function, some may sell to five or six hundred yuan, some can buy when may only need 200 multivariate ing. At present, the digital intercommunication telephone set price is similar to advanced product cost of intercommunication telephone set of simulation, so against the intersection of price and advantage to imitate intercommunication telephone set, figure talkback, think, make fast development, have the intersection of segment and very long way take, walk while being confidential.
When mentioning how to promote the development of digital intercommunication telephone set industry of China, Jiang RuiQing puts forward 3 viewpoints. He thinks, considers from technology, through adopting integrated-circuit technique, integrate center modules such as pronunciation compiled code, modulating and radio frequency of base band,etc. in the chip together, and adopt the unified interface to make up and reduce the production cost greatly, the competitive edge of domestic brand and foreign brand will lie in the chip cost advantage in the future. From the viewpoint of market, propose adopting and researching and developing and producing the industry development model that is separated in batches, can establish industry's alliance when being appropriate. Because present intercommunication telephone set enterprises are mostly small and medium-sized enterprises, technology accumulates and the fund is limited, adopt researching and developing and mode of dividing the work of batch productino to contribute to reducing enterprise's investment risk, give full play to the cooperation advantage. Enterprises need clear products to position too oneself at the same time. On the standard, still need national relevant department to make the product standard of the digital intercommunication telephone set as soon as possible, standardize the development of market.
