Impact of man access technology on future access Industry Development

The man access technology is still quite common, So I studied the impact of the man access technology on the future development of the access industry. I would like to share with you here, I hope it will be useful to you. According to the physical transmission media connected by man, the access methods are mainly divided into two categories: Wired Access and wireless access. wired access can be divided into Optical Fiber Technology and copper technology.

Currently, China's existing access networks are dominated by wired access, with copper cables). Wireless Access has been applied to access networks. No access network technology can fully meet the various business requirements of telecom operators. Therefore, what access network technology is used depends not only on the maturity of the technology, environmental factors and economic costs, but also on the main business requirements for users. Various man access technologies have different survival soil and adaptability scenarios. However, from the overall development trend of the access network technology and the popularity of broadband technology, the mainstream technologies mainly depend on the following points.

1. High bandwidth delivery capability and sustainable development capability.
2. The cost is relatively low, and the scale effect is obvious.
3. The network runs stably and is not affected by the objective environment.
4. High Security and maintenance capabilities.
5. The device structure is simple and there are few intermediate links.

From the above points, we can see that wired technology has more advantages than wireless technology, especially in terms of bandwidth delivery capabilities. Therefore, it has become an indisputable fact that wired technology occupies the mainstream. In the short term, the mainstream of the access network technology is to make full use of the ADSL2 + and VDSL2 Technology of copper cables, and the networking mode can be combined with FTTx, FTTN/C + ADSL2 + or FTTN/C + VDSL2 technology is used. With the increasing cost of EPON technology, the market share of EPON is also increasing. In the wireless aspect, 3G broadband connection technology is primarily used. These technologies have ubiquitous seamless coverage advantages and mobile features. WiMAX is difficult to implement in the short term due to problems such as high equipment prices, no suitable domestic frequency, and imperfect industrial chain.

In the long term, using fiber optics to implement ftth epon/GPON will become the mainstream of Metropolitan Area Network Access technology in the future. However, the main development trend of man access technology is broadband, mobile, optical fiber, and IP. Therefore, broadband wireless technology, especially 3G/4G high-speed broadband technology, will become the mainstream technology in the future. These mainstream technologies in the future provide great support for the business. As they provide higher bandwidth, ubiquitous coverage, and more convenient authentication and billing, many high-speed broadband services and personalized and convenient broadband services will be better popularized.

Man access technology deployment

After the restructuring of China Telecom, the three major operators will obtain 3G operation licenses and carry out full-service operation competition. There is no doubt that all operators will invest heavily in the current lucrative 3G wireless communication field. However, due to the differences in basic resources, the technical deployment of access networks varies with man.

Recent technical deployment

For the old operators, the hybrid technology that makes full use of copper resources and advances with optical fiber will be the main deployment direction, that is, the city market will adopt ADSL2 + and FTTx for joint development, ADSL2/2 + is used directly in the rural market, while EPON is used on a small scale. As emerging operators do not have the large copper resources of old operators, they focus mainly on the use of optical fiber technology for man access, therefore, EPON, GPON, and access using base station optical transmission have become the main deployment methods.

Long-term technical deployment

How to protect investment in copper resources and meet user bandwidth needs to the maximum extent has become a topic of interest to existing operators. Therefore, FTTx + VDSL2 technology may become the mainstream technology in the future, but EPON/GPON will become the main technology used for newly-built residential areas and industrial parks. As emerging operators do not have copper cable burdens, they can choose the most cutting-edge technologies to expand their competitiveness. Therefore, FTTH and FTTB technologies implemented by EPON/GPON will become the mainstream. Although different carriers use different technical deployments for their own basic resources, they all need to take corresponding measures. To make full use of xDSL technology to transmit large bandwidth services, old operators must shorten the length of copper cables for users. Therefore, the work of "light-in-copper withdrawal" will be carried out for a long time, deploying More optical fibers, pushing optical nodes to the user side, and moving DSLAM down must be carried out in advance.

Although emerging operators can directly use fiber-optic technology to achieve high-bandwidth services, the lack of basic resources such as pipelines and pole routes has become a bottleneck in their rapid expansion of the access network market. The basic network resources of emerging operators are basically carried out around the construction of base stations. Although the deployment of base stations is intensive, there is still a certain distance from physical users. Therefore, emerging operators need to increase their efforts to build basic resources such as pipelines and pole routes, and pre-cover physical resources of Group Customers, industrial parks, and key residential areas.

Impact of future man access technology applications

The value of telecom operators depends on the value they bring to customers. Any business that can bring convenience and entertainment to users and make reasonable costs will eventually have a huge market. In the future, man access technology will bring about lower bandwidth costs and wider bandwidth applications. Therefore, many businesses that cannot be carried out due to restrictions can develop rapidly. For example, IPTV can be widely used in man networks after resolving the policy bottleneck. Other high-speed video services, high-speed 3D interactive games, home network monitoring and other services will also be greatly improved. At the same time, 3G high-speed download not only brings about bandwidth, but also the spring of mobile Internet. For ordinary individual users, the ubiquitous coverage of the mobile Internet, smooth bandwidth anytime, anywhere, and personalized customization will bring great changes to personal life, users can thoroughly feel the changes brought about by the information world.

For telecom operators, in the future, the application of man access technology will greatly enrich business development and promotion. At present, the profits of telecom operators mainly come from voice. However, the profits produced by voice are gradually saturated, and the revenue and profits of new and value-added services are increasing year by year. Therefore, it is foreseeable that in the future, with the development of full-service competition, both mobile networks and fixed networks will bring a lot of broadband services.
