The Uni-RAN solution supports the evolution of Heterogeneous Networks

Heterogeneous NetworksIn the process of integration, is based on the SDR Soft Base Station TechnologyThe Uni-RAN solution is fully qualifiedIt is widely recognized by more operators and has become a mainstream network construction model.

Accelerating multi-network collaboration

The coexistence of 2G/3G/WLAN/LTE and other networks has become a trend. With the introduction of Iot/sensor networks and the development of Smart Cities, multiple heterogeneous networks overlap and coexist, its collaboration and integration development have received much attention. How to implement effective innovation to achieve complementary network performance/function advantages, achieve joint resource allocation optimization, and achieve the strategic goal of energy conservation, emission reduction, and Infrastructure Co-construction and sharing, heterogeneous Networks are of great significance to operators.

In terms of access network, operators should pay special attention to the adoption of unified platform for the adoption of innovative architecture, including the deployment of the Uni-RAN solution of and China Mobile's own C-RAN. The new architecture can effectively realize the energy-saving, efficient, virtualized, and converged Wireless Access Network of the "large capacity and few bureaus", and also realize the use of SDR radio technology and general-purpose processor platform GPP) and RF components to effectively implement the architecture expansion, upgrade, and evolution defined by the software/hardware system, as well as the joint operation of multi-frequency, Multi-standard, and multi-mode networks, at the same time, operators should also pay attention to the collaborative joint processing of effective resource utilization. Based on the Real-Time cloud architecture, they can implement the "real-time cloud computing baseband pool" to provide comprehensive information services through various cloud computing models.

Practical Challenges in integrated development

Inevitably, operators are still faced with the challenges of innovation and effective use of technologies when implementing the collaborative development of heterogeneous networks.

For example, the flexible and efficient coordination of the four subsystems in the NGN architecture, operators still face a lot of questions and practical problems, large-capacity, reliable, secure, and low-cost optical fiber remote transfer, and applications of "real-time cloud computing baseband pool" and "intelligent virtual base station" still need mature test results. In addition, operators are still exploring specific implementation strategies for small distribution componentization of base stations, energy saving and emission reduction of high-frequency antenna components, and dynamic cognitive wireless architecture.

In this environment,  uses software configuration to achieve multi-standard system integration and smooth network upgrade and evolution of the SDRs software base station based on the unified hardware platform, and the microchloroform platform architecture design adopted in subsequent development, it shows some advantages. Micromcm can make the SDR Series base stations smaller in size, lower in power consumption, stronger in processing capability, and build a network system quickly, intelligently, economically, and reliably, it also supports effective integration of multiple standards in multi-band environments. As the world's first SDR solution provider to use a unified hardware platform in 2G/3G or LTE/LTE-A,  integrated innovation architecture reflects strong market attraction and technical advantages.

The Uni-RAN solution can effectively support the convergence of heterogeneous networks. This article has made a strong note that multi-network convergence is also a hot topic in today's communication industry. I hope you will pay more attention to it.
