Classification and strategy of metropolitan Area Network access technology

The classification of metropolitan Area Network access technology can be divided into opportunistic type, application improvement type, development defensive type, leading innovation type and following imitation type. Let's explain this kind of content in detail below. Due to the change of telecom Operation Market after telecom reorganization, there are only three telecom operators left, so different operators have different consideration to the technology strategy of metropolitan Area Network access.

The old telecoms operators ' technical strategy is primarily to develop defensive-use of the market's first-served advantage, as well as a large physical infrastructure network, through lower technology costs to provide higher bandwidth to consolidate market share. At the same time, in order to prevent the emerging operators from encroaching on the market, the established telecom operators have achieved active defense by improving the stability and convenience of the technology, and cooperating with their network resources, customer resources and metropolitan area Network operation capability.

The technical strategy of the new telecom operators is to follow the imitation type + application improved type--because of the less physical network resources and the lack of user resources in the market, the new telecom operators can only catch up and actively build the basic network resources and realize the fiber to the households. At the same time, the mobile service and the fixed business are bundled, the new telecom operators to achieve the goal of the city network market by bringing more convenient informatization to the enterprise customers.

From the different telecom operators to adopt the technical strategy can be seen, the veteran operators through its past decades of copper network infrastructure resources, with a very wide range of copper cable network, and thus occupy the metropolitan area Network user market, the vast majority of the market share, to bring their own huge income.

But with the completion of telecommunications restructuring, other telecom operators in this area has no policy barriers, so the veteran operators can only side of the development side of the defense, and strive to improve the various services to retain old customers, but also with their own advantages of rapid development of new customers.

Because of the lack of the burden of copper cable network, the emerging operators can achieve the exclusive use of optical fiber, and can provide a higher bandwidth, while combining the mobile advantage of the promotion of information, through the improvement of technology applications and the promotion of updated business to develop new users.

The lack of physical network resources is a mishap for emerging telecom operators, although the basic network resources can be built through huge investment, but because the pipeline, Rod Road and other basic resources construction is not fully controlled by operators, but also with the local government, urban construction departments and properties of the cumbersome consultation, and therefore need a long time. It is also because of this, the new telecom operators in the improvement of technology applications, but still need a long time to follow the imitation of the technical strategy to develop users.

Classification of metropolitan Area Network access technology

According to the metropolitan area Network access to physical transmission media, access networks are mainly divided into wired access and wireless access two categories, of which wired access can be divided into optical fiber technology and copper technology. At present, China's existing access network to the main cable access (of which mainly copper), wireless access has begun to apply to the access network, there is no access net technology can fully meet the various business requirements of telecom operators.

Therefore, the type of access network technology depends not only on the maturity of the technology, environmental factors and economic costs, but also on the user's main business requirements. All kinds of metropolitan area Network access technology have their own soil and adaptation, but from the overall development trend of access network technology and the popularity of broadband technology, the mainstream technology depends mainly on the following points:

High bandwidth availability and sustainable development capability.

The cost is relatively low, the scale effect is obvious.

The network runs stably and is not affected by the objective environment.

High safety performance, strong maintenance capability.

The equipment has simple structure and less intermediate links.

As can be seen from the above points, wired technology has more advantages than wireless technology, especially in terms of bandwidth delivery capabilities, so the mainstream of wired technology has become an indisputable fact. In the short term, the main mainstream of access network technology is to make full use of copper adsl2+ and VDSL2 technology, and networking mode can be combined with FTTX, using fttn/c+adsl2+ or FTTN/C+VDSL2 technology.

Epon's market share is expanding gradually under the premise that the technology cost of epon is decreasing gradually. The wireless aspect mainly uses the 3G broadband connection technology, these technologies have the ubiquitous seamless coverage superiority and the movement characteristic. WiMAX due to the existence of high equipment prices, no suitable frequency in the country, the industrial chain is not perfect problems, in the short term Neinian have as.

In the long run, the use of optical fiber to achieve FTTH Epon/gpon will become the mainstream of the future metropolitan Area Network access technology. But the main trend of metropolitan area Network access is broadband, mobile, optical fiber, IP, so broadband wireless technology, especially 3g/4g high-speed broadband technology will become the mainstream technology in the future.

These future mainstream technology for the business support is larger, because it can provide higher bandwidth, ubiquitous coverage, more convenient authentication and billing, many high-speed broadband services and personalized, convenient broadband services will be better spread.

Metropolitan Area Network access technology deployment

After the restructuring of telecommunications, the three major operators will obtain 3G operating license plate, and carry out full business operation competition, no doubt for the current high profit of the 3G wireless communications field, the operators will be vigorously invested. However, there are different access network technology deployments due to the difference of basic resources in metropolitan area Network and wired technology deployment.

Recent technology deployments

For the incumbent operators, the full use of copper resources and fiber-propelled hybrid technology will be the main direction of deployment, that is, the city market using adsl2+ combined with FTTX common development, rural markets are directly using adsl2/2+,epon small-scale use.

For the emerging operators, because there is no large copper resources of established operators, so the emerging operators focus on the optical fiber technology for metropolitan Area Network access, so Epon, Gpon and the use of Base station optical transmission of access to become the main mode of deployment.

Forward technology deployment

How to protect the investment of copper resources, to meet the user's bandwidth demand, has become an interesting topic for the incumbent operators. Therefore, FTTX+VDSL2 technology will likely become the mainstream technology in the future, but for new communities and industrial parks, Epon/gpon will become the main technology used.

For emerging operators, because there is no copper baggage, emerging operators can choose the most cutting-edge technology to improve competitiveness, so the adoption of Epon/gpon FTTH, FTTB technology will become the mainstream. Although different operators have different technology deployment for their own basic resources, they need to adopt corresponding measures.

Veteran operators want to make full use of XDSL technology to transfer large bandwidth business, it is necessary to shorten the length of the user's copper cable, so the "light into copper back" work will be long-term, cloth put more fiber, the optical node to the user side, Dslam, such as the work need to be advanced.

Although the emerging operators can use the optical fiber technology to realize the high bandwidth service, the lack of the basic resources such as pipeline and Pole road becomes the bottleneck of the rapid expansion of the access network market. The basic network resources of the new operators are basically built around the base station, although the base station cloth is more dense, but it still has a certain distance from the physical users. Therefore, the emerging operators need to strengthen the construction of pipelines, Rod Road and other basic resources, and the group customers, industrial parks and key areas of the physical resources of the pre-coverage.

The influence of the application of access technology in the future metropolitan area network

The value of telecom operators depends on the value of the size of customers, any business as long as the user can bring convenience and entertainment and reasonable cost, eventually there will be a huge market. The new technology of the future metropolitan Area Network brings the lower bandwidth cost and higher bandwidth technology applications, so many of the currently restricted business can be rapidly developed in the future.

For example, IPTV in the solution of policy bottlenecks can be widely used in metropolitan area network, other high-speed video, high-speed 3D interactive games, home network monitoring and other business will also be a significant development. At the same time, 3G high-speed download brings not only bandwidth, but also the spring of mobile Internet. For ordinary individual users, the ubiquitous coverage of mobile internet, anytime, anywhere unimpeded bandwidth, personalized customization will bring great changes in personal life, users can feel the information world brought about by the changes.

The application of the future metropolitan Area Network access technology will greatly promote the development and promotion of the business. For telecom operators, this is very advantageous, the current telecom operators profit mainly from voice, but the voice of the profits are gradually reduced, and new business, value-added services brought about by the income and profits increased year by year. Therefore, it can be foreseen that the future with the full business competition, whether mobile network or fixed network, will bring many broadband services
