In communication field, the integration between fixed networks and wireless networks is already underway. Fixed networks refer to network services provided through physical lines (such as fiber optics and copper cables), which offer high stability and large capacity; wireless networks, on the other hand, transmit data through radio waves, providing flexibility and wide coverage. With the popularization and application of 5G technology, the transmission speed and stability of wireless networks have significantly improved. However, in certain scenarios, fixed networks still have irreplaceable advantages. Especially in data centers, internal enterprise networks, and high-demand household scenarios, the stability and high bandwidth of fixed networks remain unmatched. Wireless networks play a crucial role in scenarios requiring high mobility, such as outdoor activities, smart cities, and mobile offices.
Currently, the integration of fixed and wireless networks is unfolding at multiple levels. First, at the infrastructure level, telecommunications operators have begun deploying converged networks, which support both fixed and wireless networks on the same infrastructure. This not only reduces construction and operational costs but also enhances the overall efficiency and flexibility of the network. At the service level, converged networks can offer a more consistent user experience. Whether users access the Internet through fixed or wireless networks, they can enjoy the same quality of service, which is essential for improving user satisfaction and loyalty.
In terms of telecommunications application services, fixed network infrastructure has become more complete over the years. With the advent of the era of telecommunications and network integration, all application services are provided through IP network environments, and upper-layer value-added applications on the network are becoming increasingly important. Through IMS (IP Multimedia Subsystem), development can be targeted at a single platform; telecommunications operators can also provide integrated voice, data, and multimedia services through IMS, known as Triple Play communication services. The IMS system is a telecommunications architecture that provides multimedia content services across multiple platforms, enabling multimedia content providers to exchange and deliver data across different platforms (such as voice, video, and data) using IP transmission. Through the IMS platform, services can be offered across Wi-Fi, 3G, 4G/LTE, ADSL/VDSL, Cable, fiber optics, and copper cables, providing multiple services to different users. For instance, 3G/4G mobile phone users can watch cable TV programs on their phones or conduct video conferences with fixed network users. Looking ahead, the integration of fixed and wireless networks will deepen further. Here are a few key directions:
Development of 5G/6G Technology:
5G/6G technology will be the dominant force in future communication technologies, aiming to achieve higher speeds, lower latency, and greater connectivity. The integration of fixed and wireless networks in the 5G/6G era will be even closer, including the integration of transmission technologies and the deep integration of network architectures and service models.
Application of Cloud Computing and Edge Computing:
The application of cloud computing and edge computing technologies will further promote the integration of fixed and wireless networks. By distributing computing and storage resources at edge nodes close to users, the network response speed and efficiency can be significantly improved. At the same time, cloud computing centers will become the core for network data processing and analysis, supporting the operation of various intelligent applications.
Development of Smart Cities and IoT:
The rapid development of smart cities and the Internet of Things (IoT) requires highly integrated support from fixed and wireless networks. In the future, fixed networks will primarily handle large-scale data transmission and aggregation, while wireless networks will connect a large number of terminal devices and collect data. Through the deep integration of both, more efficient urban management and smarter living experiences can be realized.
Network Virtualization and SDN Technology:
The application of network virtualization and Software-Defined Networking (SDN) technologies will make the management and operation of fixed and wireless networks more flexible and intelligent. Through software control, network resources can be dynamically allocated based on real-time demand, achieving automated and intelligent network management.
Security Assurance:
As network integration deepens, network security issues will become more prominent. In the process of integrating fixed and wireless networks, security must be a key focus, with multi-layered security protection systems established to address various potential threats and risks.
