Summary

As a result of RAN Centralization, mobile networks can now be managed in cluster modules rather than site modules. This allows for a baseband to manage hundreds of sectors instead of just 3, bringing a level of efficiency and flexibility previously unimaginable in the wireless industry.

Parallel Wireless’ RAN Centralization technology is the next evolutionary step of the cellular industry. Traditionally, mobile networks have been operated, deployed, and managed through a distributed system, where functions are spread across multiple cell sites and require dedicated infrastructure and resources at each site. This inflexible and resource-intensive approach makes it difficult for mobile network operators (MNOs) to respond to dynamic changes happening across the network.

As a result of RAN Centralization, mobile networks can now be managed in cluster modules rather than site modules. This allows for a baseband to manage hundreds of sectors instead of just 3, bringing a level of efficiency and flexibility previously unimaginable in the wireless industry.

RAN Centralization offers greater network elasticity and resilience. In a centralized RAN architecture, the network can be elastic and respond to dynamic changes in real-time, improving resource utilization and enabling self-healing. With this technology, MNOs can also take advantage of the latest innovations and technologies to boost the performance of their networks, such as full CoMP, multi-site CA, and multi-site MU-MIMO.

Another key benefit of RAN Centralization is increased spectrum efficiency. Since the centralized RAN controls the entire cluster, carrier balancing and subscriber steering is a holistic part of the network. This results in greater efficiency of the given spectrum compared to site architecture. In addition, RAN Centralization allows for advanced approaches for data center utilization, such as region/cluster level resource pooling and sophisticated resiliency mechanisms, which can drive compute and memory allocation per carrier/site down by as much as 50%.

Additional benefits of RAN centralization include cost savings. Centralizing RAN functions can reduce MNOs’ CAPEX and OPEX expenses. By sharing resources across multiple sites, a more efficient network is created, a smaller footprint is created, and power consumption is reduced.

In conclusion, with numerous benefits, including reduced costs, increased network capacity, and improved network coverage, RAN Centralization makes it easier for MNOs to respond to dynamic changes and meet the evolving needs of their customers. This groundbreaking technology has the potential to fundamentally change the wireless landscape.
