China Putian says 3G is more suitable for wireless city construction

According to relevant statistics, in 2007, there were more than 1,000 "wireless cities" under construction and planning in the world. Overseas agencies predicted that by 2010, the number of global "wireless cities" would increase to 1500. Obviously, the global "wireless cities" The general trend of construction has formed a trend in today's world.

China Putian recently told NetEase Technology that China's wireless city construction is suitable for the use of government applications as a guide, and then cultivate the use of the public and develop public applications, and then start commercial applications. In terms of network construction technology, due to the advantages of cost and policy, the 3G standard will surely become the mainstream technology in the "wireless city" network. Among them, TD-SCDMA has government support and national network advantages, and it should become a domestic "wireless city" construction. The main force.

Overseas wireless city operation encounters obstacles

As a "fifth public utility", "wireless city" will improve the efficiency of government and enterprises and reduce operating costs; improve public services and enhance public safety; eliminate the digital divide and improve people's lives; optimize the investment environment and promote economic prosperity. Therefore, the concept of "wireless city" has been popular among governments around the world since its emergence.

Under such circumstances, traditional telecom operators have entered the construction of "wireless cities" in large numbers, making the sustainable development of "wireless cities" possible. Traditional telecom operators have a huge user base. The emerging "wireless city" business can be expanded on the basis of the original voice and data services, which is equivalent to using the existing network to provide higher value-added services.

However, it is worth noting that there are many builders participating in the "wireless city" around the world, but there are not many successful cases that truly realize the good operation of the "wireless city".

In 2008, when the construction of domestic "wireless cities" was booming, many foreign "wireless city" operators announced their withdrawal from their operations. For example, MetroFi, the largest wireless city service provider in the United States, announced in June 2008 that it would suspend wireless city construction nationwide. . Like most new things, the "wireless city" has gone through four stages of "proposed concept-> bubble-> bubble burst-> rational development" in just six years.

The business subjects of the wireless city involve: the government, enterprises, and the public. How to serve the above commercial subjects has become a key factor in wireless city business route selection. The different "wireless city" business routes are classified as follows: one is to take government applications as the guide, cultivate people to use and develop people's applications as the second step, and start commercial applications as the third step; the other is based on the basic access of the people The first step is to satisfy government applications, and the third step is to start commercialization. There is also a third route: using commercial applications as a guide. Allocate certain resources to government affairs and the people.

3G is more suitable for wireless city construction

At present, the following four access technologies are mainly used in the construction of "wireless cities" in the world and in China: TD-SCDMA technology, WiMAX, Wi-Fi and Wi-Fi Mesh.

Among them, WiMAX, Wi-Fi and Wi-Fi Mesh are all proposed by the IEEE organization. The protocol design is developed from fixed broadband to mobile broadband. Due to the influence of traditional wired transmission characteristics, there are some deficiencies in wireless applications, such as: The capabilities of wireless security, QOS, centralized operation and maintenance are weak. Some emerging operators hope to use these new technologies to build wireless cities. Due to technical deficiencies and limited financial capacity, the construction process is often stalled.

In fact, while many foreign operators have stopped using WiMAX and other technologies to build wireless cities, since 2008, many traditional telecom operators have joined the construction of wireless cities, which marks the "wireless city" entering a period of rational development.

Putian believes that when traditional telecom operators become the main body of the "wireless city" construction, they decided that the 3G standard will become the mainstream technology in the "wireless city" network.

Combined with the current status of the domestic telecommunications industry, traditional telecom operators' participation in the operation of "wireless cities" and the maturity of 3G networks have truly provided the ideal operation mode for the operation of "wireless cities".

China Putian said that the rapid formation of a win-win situation is based on the obvious advantages of the TD-SCDMA network "wireless city", which is beneficial to all parties: telecom operators can use the "wireless city" to expand 3G users and develop TD-SCDMA. bedding. With the shortage of funds in the information departments of local governments, traditional telecom operators are urgently required to enter the construction of "wireless cities" to continuously improve the level of urban informatization. The two hit it off, and the TD-SCDMA network will surely become the main force in the construction of the domestic "wireless city".

TD has obvious advantages in building a wireless city

Building a "wireless city" business with TD has obvious technical and economic advantages. In terms of cost, the current major operators are planning to build 3G networks, and relying on these network foundations to establish "wireless cities" will certainly save a lot of construction costs.

In terms of policy, TD is a 3G standard with independent intellectual property rights in China, and the TD industry chain needs the cultivation of the Chinese market. The Chinese government is bound to give certain policy support to create a good TD development environment.

In terms of integrating the industrial chain. Telecommunication operators can build an operation mode that can operate benignly, quickly strengthen the industrial chain, and create a good multi-vendor supply environment, which will play a key role in the future booming development of "wireless city" feature applications.

In terms of business promotion advantages, telecom operators have been subdividing and researching users for a long time in the 2G era, forming many different user groups, and have mastered a set of perfect methods for subdividing users. Therefore, in the operation of "wireless cities", telecom operators can use the current group segmentation strategy to provide different value-added services to different users.

China Putian said that the official commercial use of the TD-SCDMA network has brought new opportunities for the development of "wireless cities". At the same time, the maturity of the TD-SCDMA network provides a powerful technical guarantee for the data service of the "wireless city".
