OpenRAN

OpenRAN’s mission is to accelerate innovation and commercialization in RAN domain with multi-vendor interoperable products and solutions that are easy to integrate in the operator’s network and are verified for different deployment scenarios. TIP’s OpenRAN program supports the development of disaggregated and interoperable 2G/3G/4G/5G NR Radio Access Network (RAN) solutions based on service provider requirements.

Key OpenRAN tenets include:

1. Disaggregation of RAN HW & SW on vendor neutral, GPP-based platforms
2. Open Interfaces – Implementations using open interface specifications between components (e.g. RU/CU/DU/RIC) with vendor neutral hardware and software.
3. Multiple Architecture Options, including
   1. An all integrated RAN with disaggregation at SW and HW level
   2. A split RAN with RU, BBU (DU/CU)
   3. A split RAN with RU, DU and CU
   4. A split RAN with integrated RU/DU, CU
4. Flexibility – Multi vendor solutions enabling a diverse ecosystem for the operators to choose best-of-breed options for their 2G/3G/4G and 5G deployments
5. Solutions implemented on either Bare Metal or Virtualized or Containerized Platforms
6. Innovation via Adoption of New Technologies (AI/ML, CI/CD…)
7. Supply Chain Diversity

Northstar for OpenRAN is to drive abundant last mile wireless connectivity. OpenRAN plans to achieve this through developing a vibrant ecosystem that is:

1. Rapidly innovating at every layer, every component of the RAN technology stack, and
2. Continually improving the performance of RAN through innovation, automation and competition

TIP’s Open RAN System Certification process (SCOPE): Aligning the Industry and Accelerating Open RAN Commercial Deployments

There are clear, well-documented benefits to developing a network made up of disaggregated, open solutions that include innovation, increased choice of suppliers and also lower TCO. However, integration and testing have become significant tasks for operators. Many call for more help integrating Open RAN systems and accessing tested market-ready solutions that meet their requirements. TIP’s planned Certification process, called SCOPE, is the solution. It is designed to create significant structural efficiencies within the supply chain to streamline efforts across operators and their vendors and reduce the complexities inherent in the integration and testing of carrier-grade Open RAN.

How TIP is bringing market-ready Open RAN solutions together

TIP’s test and validation program, and industry alignment, can accelerate development and adoption of commercial, carrier-ready solutions. Open RAN solutions are designed to give operators optionality in their choice of suppliers across the value chain.

By disaggregating the different functions of the network, operators can deploy networks made up of solutions from different vendors within the technology stack. This gives them several benefits.

They can access solutions that they feel are best of breed or best suit their purpose, without having to buy all parts of the solution from the same vendor. Similarly, they can update and upgrade software and hardware independently, instead of being dependent on the upgrade roadmap of just one, integrated vendor.

Quantifying Mobile Network Requirements by Use Case in the Outdoor Urban Environment

An understanding of the trends in demand (number of users, bandwidth, latency) due to the growth in existing mobile use cases and the emergence of new ones is important for the planning of mobile network deployments. This is particularly important in the outdoor urban environment where there are few alternative connectivity solutions.

The purpose of this study is to identify the existing and emerging connectivity dependent use cases that are, or will be, heavily used in the next 2-5 years, and evaluate whether they require a significant connectivity upgrade.

OpenRAN ROMA CD/CT OpenRAN Automation White-Paper

One of the biggest challenges often raised in the industry is the complexity of Open RAN automation i.e CD/CT (Continuous Deployment/Continuous Testing). This challenge comes as no surprise as Open RAN represents one out of many examples where systems get disaggregated into smaller pieces. Such dis-aggregation inevitably calls for the corresponding aggregation – i.e., the integration. Open RAN is (in many of the cases) a multi-vendor exercise where vendors of various parts of the RAN as well as infrastructure vendors need to come together and make sure their products are interoperable in the configurations requested by the market.

This white paper aims at outlining the challenges, industry best practices and standards in integrating the CD/CT platform for Open Radio Access Networks (Open RAN). The paper follows on from our previous paper titled “TIP OpenRAN White Paper Toward OpenRAN CICD Automation October 2020” Therefore, readers of this white paper are encouraged to read the previous one as an introduction, thus also familiarizing themselves with the concepts of virtual RAN, Open RAN and Continuous Deployment.

The Economic Impact of Open and Disaggregated Technologies and the Role of TIP in India

In India, mobile operators have been actively exploring the use of open and disaggregated technologies in their networks, and have also started to develop in-house solutions that can be exported globally (if and when proven) and scale beyond India to the world. The government of India is also taking steps to strengthen local manufacturing capabilities. This involves incentivising large global players to set up production facilities in India. More importantly in the context of open and disaggregated network technology, the government’s efforts also include supporting homegrown companies to develop solutions that could meet local demand for network equipment and software for years to come, while also exploiting opportunities in the global export market. The supply chain ecosystem in India, made up of original design manufacturers (ODMs), vendors and systems integrators, is also responding to growing demand and government-backed initiatives by developing new disaggregated solutions spanning various network parts and by continuing to foster relationships with international customers to capitalise on emerging export opportunities.

India is expected to be at the forefront of open and disaggregated technology adoption and production in years to come due to the amount of activity driven by its operators, the government and supply chain participants in developing open and disaggregated technologies. For Open RAN alone, Analysys Mason estimates that the incremental GDP impact in India could reach USD18 billion per annum in 2030 (USD58 billion cumulatively from 2021–30), driven by enhancements to mobile internet penetration and data usage. Modelling suggests that these impacts could more than double over the period from 2021–30, should industry facilitation initiatives driven by operators, the government, as well as organisations such as TIP be as successful as envisaged by many of the stakeholders driving Open RAN in India today.

This report follows Analysys Mason’s global study, published in May 2021, looking specifically at developments related to open and disaggregated technologies in India.

OpenRAN: The next generation of radio access networks

Current Radio access networks (RAN) require significant upgrades to keep up with increasing data demand. Operators will be compelled to evaluate new RAN technology from various technology providers. The OpenRAN project group was created to focus on developing a vendor-neutral hardware and software-defined technology based on open interfaces and community-developed standards. Unlike traditional RAN, OpenRAN decouples hardware and software. This gives operators more flexibility to deploy and upgrade their network architecture in various deployment scenarios and geographies.
