The

OpenRAN

Project Group is an initiative to define and build 2G, 3G, 4G, and 5G RAN solutions based on general-purpose vendor-neutral hardware, open interfaces and software.


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

5G New Radio: Revenue and Deployment Opportunities
 
Telecommunications operators face a dilemma with the 5G business case: the deployment of 5G requires significant capital investment and the rate of return is not as straightforward despite the potential of 5G technology. RAN, the largest cost in wireless network architecture, is pushing operators to rethink their current deployment paradigms. Responding to this challenge, Telecom Infra Project (TIP) has created an ecosystem that is founded upon collectively designing and building new technologies to accelerate innovation.

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.
