Accelerating the development of instrumentation, making up for weak links in the instrument and reducing the cost of TD terminals is a good opportunity for the instrumentation industry. For this reason, industry professionals have conducted detailed planning. The following describes the object.
TD-LTE industry is suddenly clear TD-LTE has been selected 4G standard is no suspense, Yang Hao used "abruptly clear" words to describe him optimistic about the development of TD-LTE, China Mobile as an operator to participate in TD-LTE to promote the industry Rapid development. “This is not the same as the 'pain' of TD-SCDMA in the early days. Because there is no clear commitment from operators, the market prospect of TD-SCDMA is always in an exploratory state, and some companies are “looking forwardâ€.
Although Yang Hao is very optimistic about China Mobile’s push of the TD-LTE industry, China Mobile’s top management is also calling for a clearer definition of TD-LTE frequencies as soon as possible and early allocation, and accelerating the global allocation of mobile broadband TDD frequencies. Spectrum allocation plays an important role in demonstrating the industry’s clearer R&D direction and avoiding product development around detours. Analysts have pointed out that in WiMAX, the development of WiMAX operators in developed countries is currently slow, and representative WiMAX operators have begun to turn to LTE. The development of TD-LTE is still facing strong pressure from WiMAX. If it cannot develop as quickly as possible, WiMAX will have a comeback. Potential.
According to the data disclosed by the relevant senior management of China Mobile in public, at present, TD test meters have grown from the initial 10 to the current 50.
For the overseas development of TD-LTE, Yang Hao pointed out that since 4G has not yet begun to develop, TD-LTE will have far greater room for development than TD-SCDMA, not only the emerging markets where TD-SCDMA does not have 3G. The convergence of TDD LTE and FDD LTE will inevitably gain the support of international manufacturers. At present, the TD Industry Alliance is cooperating with the government in organizing the LTE R&D and industrialization related work. At the same time, it will also sign MOUs with international operators to promote TD-LTE testing.
On the terminal side, Yang Hao stated that the cost, quality, and stability of TD terminals and other standard terminals are basically at the same level. China Mobile invested 600 million yuan last year, and joint research and development with chips and terminal manufacturers incited industrial development. And half a year ago, related media reported that the cost of TD terminals is still higher than that of other standard terminals by 20%. However, Yang Hao also bluntly mentioned the lack of TD chips - the cost of chip integration may still be inferior to WCDMA, which restricts the development of personalization of mobile phones. There are tens of thousands of manufacturers involved in the 2G era, the terminal is relatively simple, and the supporting is perfect. However, many aspects such as chips and protocols in the early stage of 3G industry development are not mature enough, the technical difficulty is much higher than 2G, and 3G terminals integrate a large number of applications. The number of components has greatly increased, and the integration of diverse components has increased the difficulty of terminal manufacturers' integration. In addition, software is also crucial to the terminal, and compatibility between software cannot be ignored.
In terms of network performance indicators, the TD-SCDMA index is close to 2G, the connection rate has increased from 86% in April 2008 to the current 99%, and the dropped call rate has dropped from 6% to 0.3%, which will directly increase the user's TD- SCDMA terminal user experience. This directly reflects the gradual increase in the proportion of data traffic on the TD network. From May 2009 to April 2010, China Mobile’s total data traffic increased by 2.1 times, T-net traffic increased by 10.1 times, and G-net traffic increased by 1.6 times; TD data traffic increased from 6% to 30.7%.
In the initial stage of terminal industry development, many manufacturers must participate in order to accelerate the maturity and development of the entire terminal industry. "The promotion of public boards is helpful for improving the industry and accelerating development in the early stages of 3G. A few manufacturers with design capabilities can develop stable and reliable public boards, and most manufacturers can package them from the design of peripherals, components, and structures. The terminal supports and provides users with a better experience and enhances their R&D capabilities for 3G terminals.†Yang Hao predicts that the public board will play an active role in the early 3G period of 2-3 years, but he also pointed out that it is mature. In the period, the public board will hinder the development of the 3G industry. Especially after the user's needs are stimulated, the public board will become simpler and more modular, and it will not be able to meet the diverse needs of users.
China Mobile four networks have their own positioning for the 2G/3G/TD-LTE/WLAN four networks mentioned in China Mobile's internal conference, Yang Hao believes that operators will gradually adjust the pace of network construction rely mainly on "best input and output," “The four networks have different needs. GSM is the foundation of China Mobile, and China Mobile’s main profit comes from GSM.†After more than a decade of development, GSM has basically formed a seamless network, and 3G and LTE networks will inevitably experience From the time of partial coverage to wide-area coverage to the final completion process and it takes a long time, the voice service as the basic requirement of the user is the first consideration for the mobile operator.
As of the end of August 2010, the total number of mobile subscribers in China has reached 564 million, and the total number of TD users on the network has reached 13.419 million. The number of GSM base stations in China Mobile has exceeded 600,000, and the number of GSM base stations in the United States has not reached 300,000. .
According to Yang Hao, 3G has three technological standards in the world, "it is difficult to globally roam the same terminal." This is another important reason why China Mobile did not give up GSM in the 3G era. Although 3G carries the mission of converting voice to data services, there is no explosive growth of 3G expected from the domestic and global markets. “There are major factors in changing consumer spending habits, and users’ acceptance of 3G terminals and services. The degree has yet to be improved. For example, the shift from paper to audio-visual electronic reading habits requires a process.†Prior to this, China Mobile formed several business bases. Later in August this year, China Mobile’s joint Communist Youth League launched MM million youth. Entrepreneurship plan, “This reduces the threshold for business development and enriches business development. 3G needs a lot of applications such as video, games, and fashion. It is difficult for operators and CP/SP to meet the broader market demand in the future.†The trial and operation of TD-LTE will directly affect the development of LTE TDD. China Mobile executives stated that the development of TD-LTE in the world depends on China. When China's TD-LTE is deployed and commercialized in scale, it will directly determine the confidence of international industries and markets. International operators have the will to TD-LTE, but they lack the Chinese market. Leading, many operators are unable to make up their minds.
In the TD-SCDMA network construction, China Mobile added nearly 100 cities in the fourth phase. Compared to the 238 cities in the first three phases, the increase in urban coverage in the fourth phase was not significant, mainly because China Mobile is in the TD-SCDMA network. While building a base station with a certain scale to drive the development of the industry, a gradual network deployment strategy has been adopted in accordance with the gradual development of 3G applications. In cities where TD networks are covered, the capacity of the local network is increased based on the user's demand for business growth. According to third-party data, 70% of 3G data services are initiated in indoor areas. In the fourth phase of TD construction, China Mobile has increased the coverage of TD network indoor coverage to expand indoor distribution.
For the development of TD-LTE, Yang Hao believes that China Mobile is now vigorously promoting the industrialization of LTE in order to gain the upper hand in the next generation of mobile communications. At the same time, TD-LTE will effectively increase data throughput, further extend the transition from narrowband to broadband, and help operators promote the development of high-speed video and other high-rate services. At the same time, TD-LTE will effectively solve frequency resources due to TDD-based technologies. The bottleneck, and the use of smart antennas will reduce cell interference and other issues.
In addition, as to why China Mobile is focusing on the development of WLAN networks this year, Yang Hao believes that "the cost of cellular mobility is high, and the improvement of 3G capacity is limited after all. The combination with WLAN is a very good complement."
Instrumentation is no longer weak Because of the early understanding of the concept of TD industry is not deep, test instrumentation started relatively late, was Yang Xi as "TD-SCDMA pain", and the early days of instrumentation mainly in foreign manufacturers, "They do not We are optimistic about TD, but the emergence of international manufacturers' development advantages in LTE will force domestic manufacturers to switch from pressure to power. As an operator, in the initial stage of TD-SCDMA network operation, China Mobile has a low success rate of interoperability between the existing network and the TD-SCDMA network. Network testing and optimization tools are scarce. Off-network, crashes, and inaccessibility occur frequently. Feeling bad. China Mobile has carried out related technical innovations in various aspects such as the revision of standards, process optimization, equipment algorithms, and interface transformation to solve interoperability problems. At the same time, the network optimization efficiency has been greatly improved through innovative network optimization tools such as automatic optimization of neighborhoods and terminal tracking and positioning tools.
At present, as far as LTE is concerned, domestic and foreign system manufacturers have basically launched their own TD-LTE system products as long as they participate in TD-SCDMA R&D. After completing the verification and demonstration of the respective systems, IOT tests between different systems are now carried out, and IOT testing will enable the system equipment of each vendor to have outdoor large-scale networking capabilities.
In terms of TD-LTE terminal chips, there are currently 2 to 3 chips of products serving the TD-LTE demonstration of the Shanghai World Expo. It is expected that 5 to 6 chip manufacturers will provide TD-LTE chips for vendor verification tests in the first half of next year.
It is reported that the development of TD-LTE conformance testing code began in early 2008 and was officially launched in 2009. Now more than half of the use cases have been developed, and more than 100 test cases have been used for chip testing. "TD-LTE meter development progress and the system and chip are basically in sync. Now we have a prototype of the terminal's test prototype and conformance test system." Yang Hao said that the instrument is no longer a weak link in the TD industry.
