Looking forward to the future development of Wireless Access Networks

Wireless Access networks are quite common. So I have studied the future development direction of wireless access networks. I would like to share with you here, hoping to help you. The wireless access network market is a field where multiple new and old technologies are competing, multiple transmission means are competing, and multiple transmission systems are also affected by policies and regulations. The type of wireless access network should be determined based on the actual situation.

As far as China Telecom Network is concerned, it has been accumulating for decades and has a large twisted pair Cable Network. using ADSL technology will be a good choice. As a mature technology, ADSL has been widely used in North America and is providing excellent services. For cable TV systems, cable-based access is primarily used to connect users. Although cable TV started late in China, it has developed rapidly. At present, there are already 80 million cable TV users in China, and the bandwidth of up to 1 Gbps is the biggest advantage of the cable system. The fiber-optic copper cable-based architecture of the HFCs network will be the best choice for cable TV wireless access networks.

However, to provide interactive data communication, the HPC network is facing two-way transformation. The dense Chinese residents and the aging of cables make the return system generate a difficult funnel noise problem, making bidirectional transformation difficult. The user group can only be within a small range. People have come up with various ways to solve these problems. Wireless Access networks will become increasingly important in areas with low-density scattered small user groups, areas requiring urgent telephone user lines, and areas with geographical barriers. For areas under construction of a fixed wired access network, the wireless access network can be used as a transitional means to quickly provide new user lines. Once the Wired Access Network is built, the wireless access network system can be moved to another place for use. In the rural network environment, the one-point multi-access wireless technology is economical and flexible.

The common trend of the access network is to gradually push optical fiber to users. FTTC will gradually develop towards FTTH, while HFCs will gradually develop from a large node to a small node, and then gradually promote the optical fiber to a pivot point (FTTT) or even implement f tth. After the optical fiber arrives at the household, it eliminates the metal wire in FTTC and the coaxial cable in HFCs, avoiding metal corrosion and other problems, and the bottleneck of the wireless access network disappears. However, fiber-to-the-home migration is a long process and requires a large amount of money and manpower. Therefore, hybrid access mode is usually used. For example, a hybrid access mode is adopted in the environment where, the combination of FTTC and VDSL technology provides an optimal balance between optical fiber laying cost, electronic equipment cost, and bandwidth capability. It is also a realistic and ideal broadband hybrid access solution.

In short, with the increasing number of wireless access networks, such as VOD, distance education, remote medical care, and interactive image games, the network bandwidth required will become wider and wider, more and more interactive, broadband wireless access network will be an inevitable trend. The access network market will become one of the hottest markets in the information industry in the next few years, and people's lives will also change.
