Open RAN

 

Accelerating Network Transformation through Disaggregation

Open RAN represents a significant shift in the Radio Access Network (RAN) architecture. While traditional RAN systems use proprietary, hardware-centric technologies, Open RAN introduces an open, intelligent, and flexible approach to network construction. The concept is anchored on the disaggregation of hardware and software. It leverages standard processors and open interfaces to develop a robust and versatile network architecture. The concept of Open RAN (often referred to as O-RAN) is rooted in the standards set by the O-RAN Alliance. Established in 2018 by a consortium of service providers, the O-RAN Alliance aims to specify requirements and harness the potential benefits of open RAN architecture. O-RAN is characterized by four key functional blocks: Virtualized Distributed Unit (vDU) supporting Remote Radio Units (RRUs) Multi-connections, radio access technology (RAT) agnostic Virtualized Centralized Unit (vCU) RAN Intelligent Controller (RIC) Centralized management and orchestration The above components work synergistically to form a flexible, intelligent, and cost-effective RAN, which can dynamically adapt to varying network demands.

From Legacy RAN to Open RAN: An Evolutionary Perspective

Traditional RAN architectures were based on the Distributed Radio Access Network (D-RAN) model. Here, Baseband Units (BBUs) and Remote Radio Heads (RRHs) were proprietary and usually co-located at the same cell site. The move towards a Centralized RAN (C-RAN) saw the creation of a “centralized BBU pool.” However, the Common Public Radio Interface (CPRI)-based fronthaul struggled to meet the capacity and performance requirements of 5G networks. Both D-RAN and C-RAN architectures come with high operating expenses (Opex), underutilization of RAN resources, and limited deployment flexibility for 5G. Cloud RAN, or C-RAN, emerged as a solution to these challenges. It built upon the centralization concept by running virtualized baseband functions on Commercial Off-The-Shelf (COTS) server hardware. This model leveraged Network Functions Virtualization (NFV) to create a more flexible and scalable architecture.

The Cloud RAN paradigm gradually evolved into Open RAN, expanding on openness and embedded intelligence principles. The openness in the architecture facilitated multi-vendor deployments, reducing vendor lock-in and promoting competition. The embedded intelligence leveraged advanced technologies like Machine Learning (ML) and Artificial Intelligence (AI) to automate operational network functions, further reducing operational costs. Overall, Open RAN represents a substantial progression in RAN architectures, offering benefits in terms of cost, flexibility, and performance. Open RAN is poised to play a pivotal role in 5G deployments and beyond by embracing open standards and intelligent functionalities.

Radisys also plans to evolve this solution further to support higher capacities and data rates by leveraging carrier aggregation across 10 carriers with a total bandwidth of 1000 MHz on the Qualcomm FSM200 platform.

Harnessing CBRS: A New Era of Network Coverage

Radisys has pioneered the implementation of Citizen Broadband Radio Service (CBRS) via Open RAN, bringing a new level of flexibility to the wireless deployment model. CBRS, a radio-frequency spectrum that spans from 3.5GHz to 3.7GHz, was established by the Federal Communications Commission in 2015 as a shared spectrum. This spectrum offers tiers of usage for incumbent users, priority licensees, and generally authorized or lightly licensed users. Designed for the US market, the CBRS band aligns with the 3GPP Band 48, and overlaps Bands 42 (3400–3600 MHz) and 43 (3600–3800 MHz). CBRS facilitates a robust, LTE-like private network performance with the simplicity of Wi-Fi. For CBRS-based deployments in LTE and 5G New Radio (5GNR), Radisys offers integration with small cells and Distributed Units (DU) through a Spectrum Access Server (SAS) agent or a domain proxy. Radisys has also contributed an Automated CBSD Certification Test Harness to the CBRS Alliance for its OnGo certification program. Radisys has developed a Test Automation Platform and Software Framework for CBRS that accelerates market readiness and commercialization. This platform employs a spectrum analyzer to monitor RF emissions from CBSDs, an SAS emulator, and automation instructions to execute CBRS scenarios to ensure compliance with CBRS specifications.

Organizations globally are tapping into the vast potential of the Operational IoT market, from transforming weather monitoring in remote mines to ensuring safe drinking water in African communities. The real game-changer is the integration of reliable, cost-effective satellite connections, predicted to rise to tens of millions by 2030. These connections make it possible to transmit data periodically rather than in real-time, reducing costs and meeting the specific needs of industries like agriculture, shipping, and environmental monitoring. The challenge for Systems Integrators (SIs) is to ensure their Satellite IoT deployments are not only technologically viable but also commercially successful. Ensuring robust satellite coverage, cost-effective deployment, and prolonged battery life are essential to this business case. Forward-thinking SIs have already started their journeys, optimizing Satellite IoT solutions, proving its business worth, and preparing for large-scale deployments.
