TD-SCDMA is calculated: 3G early Licensing conflicts will be much smaller

4G LTE commercial is in full swing, domestic 3G standard TD-SCDMA has recently been placed on the cusp.

According to reports, with the advent of the 4G era, China Mobile will no longer add TD-SCDMA new investment, TD-SCDMA may be the most short-lived one of the 3G network, and previously invested in TD-SCDMA 200 billion will never be returned. The report cited respondents as saying that TD-SCDMA delayed China's entire telecommunications market, the development of users and the entire industry paid a price. TD-SCDMA has been granted a lot of pieces, becoming a drag on China Mobile and the development of Chinese telecommunications "culprit."

In fact, since the emergence of TD-SCDMA, there are also opponents of strong, the topic has never been severed. TD-SCDMA in the domestic communications industry is more than the development of the work, or more than the work, the beholder, benevolent.

"3G licensing in advance will be a lot less conflict."

"Everything has two sides, stand in their own perspective to evaluate, the result is not the same." "About the TD-SCDMA debate," said Yang Peifang, director of the China Information Economics Society.

TD-SCDMA was formally adopted as the international 3G Standard in May 2000, with the three major standards set out in the WCDMA and CDMA2000 proposed by the United States.

While becoming an international standard, TD-SCDMA and two other standards have long been separated in business time. WCDMA was officially commercially available as early as 2001, and CDMA2000 commercial was almost at this time, and China was not officially licensed until 3G in early 2009. It is a vicious circle that China's standards are not commercially available in China, which has not been supported by TD-SCDMA at home and has been slow to progress domestically.

In the domestic 3G before licensing an interview, Yang Peifang said TD-SCDMA to get the market to temper, "light and so on, this is not to protect it, but will harm it." "TD-SCDMA business process is slow, an important reason is the lack of industrialization."

"National Development and Reform Commission economic System and Management Institute, director of Industrial Room" Swit many years ago in Datang Mobile research, he felt that Datang Mobile is not like a business enterprise, more like a research institute, and ZTE, Huawei and other manufacturers in TD-SCDMA industrialization is the pace of separation. "If the Datang mobile score, I think in the development phase of TD, you can play 100 points, testing phase can give 60 points, and in the industrialization and market operation can only play 10 points." "Swit wrote in his blog.

Recently in the "It Times" reporter interview, Yang Peifang said that China's 3G decision-making time is too long, leaving 3G to develop the window period is too short, so that contradictions appear more prominent, "if the early years, the situation will be much better." ”

Independent intellectual property "Shing"

In this criticism of TD-SCDMA, "independent intellectual property rights" has become the focus of contradictions.

TD-SCDMA has been known as the domestic 3G standard, but the domestic standards in the end contains how much "independent intellectual property rights", has been no clear statement. And it is said that TD-SCDMA is not China's own development of standards, in fact, Siemens and Datang together to get out.

How many "independent intellectual property rights" are there in TD-SCDMA? 2002 the original Mii Telecommunications Research Institute of the 3G Standard-related patent investigation report disclosed that in the TD-SCDMA patent, Datang accounted for only 7.3%, later this data is widely cited, but this data is too long. In 2006, the consultancy, Novartis released a report that decomposed TD-SCDMA patents into two parts of TDD patents and SCDMA patents, where Datang, Huawei and ZTE accounted for nearly 30% per cent of the TDD patents, with a higher percentage of SCDMA patents. The report was refuted by Datang, saying TD's core patent must be in the hands of Datang.

TD-SCDMA in the end, how much is from the domestic manufacturers of patents, the relevant departments and enterprises have not disclosed, has become a mystery.

For TD-SCDMA technology from Siemens, Ministry of Communications Technology Committee members, well-known telecommunications expert ziqiang to the IT Times reporter, TD-SCDMA has a part of the patent from Siemens, but the subject is still China, "in Europe to determine the WCDMA 3G standards, Siemens did not do it." Later, Siemens joined up with the China Post and Telecommunications Research Institute (formerly known as Datang Telecom Group) to develop TD-SCDMA.

"Independent standards do not necessarily mean that all are their own, and the synthesizer is also a contribution," Yang Peifang.

More work than work?

In the process of the development of domestic mobile communication, TD-SCDMA is more work or more than work?

A few years ago, Ziqiang has been using two mobile phones, a TD-SCDMA, a WCDMA, in mobile phones are loaded with the speed of software, to a place he is always used to take out the speed, "TD-SCDMA mobile phone significantly poor, poor experience." "China Mobile invested billions of dollars to build TD network and subsidies TD mobile phone, the result is TD data business income is very low, only play a small part of the role of voice traffic diversion." From this perspective, TD-SCDMA is unsuccessful.

Ziqiang that although TD-SCDMA's network performance and user experience is not good, but completed its own historical mission. From the point of view of the industrial chain, Ziqiang that TD-SCDMA has led the development of telecom equipment manufacturing, chip design and handset manufacturing industry, which is successful in this sense.

"There has been a massive increase in 3G users, driven by China's move." And because foreign enterprises do not want to do, so the domestic chip, equipment, instrumentation, testing and other aspects of the manufacturers to benefit from the Philippines, promoting the domestic communications enterprise industry chain growth. ”

Telecom senior Observer Liang also said that TD-SCDMA is China's autonomous development of the project, China Mobile in the 3G to 4G in the industrial ecology of the accumulated experience, such as how to promote a rapid commercial technology, but also found a lot of correct solutions, "at the same time, It also makes China have a certain right of discourse in the international standard formulation. ”

Ziqiang that more than 200 billion of investment in TD-SCDMA could not be withdrawn is not entirely true. Currently in the TD-SCDMA network of Acer Base station, a large number of dual-mode smooth evolution of the ability to do without complex equipment replacement, just a simple project transformation and software upgrades, you can upgrade to LTE dual-mode site. "This actually saves LTE investment. "Ziqiang said.

However, Liang that TD-SCDMA 3G users have negative growth, and China Mobile has invested nearly 200 billion yuan in the capital, investment in large output is not obvious, "although China Mobile in 4G early to take a step, earn back the user, but also make up for the loss of 3G."
