Mobile Test Summit 2023

Open RAN

Making open virtualized networks a reality

Testing and certification to ensure interoperability for O-RAN-based networks

Open Radio Access Network (O-RAN) is a new approach to designing and deploying mobile networks. Traditionally, mobile networks have been built using integrated, proprietary systems where hardware and software come from a single vendor. O-RAN, on the other hand, does not use one big, closed system from a single company. Instead, it promotes an open and interoperable architecture, allowing cellular equipment from different vendors to work together. O-RAN fosters a more competitive and dynamic ecosystem, reducing costs, accelerating innovation and ultimately improving the performance of mobile networks.

Key topics for O-RAN:

  • O-RAN markets, opportunities and challenges
  • O-RAN solutions for lab and field
  • Testing next generation infrastructure equipment in production
  • Critical design considerations for massive MIMO
  • Base stations testing from FR1 to sub-THz
  • Maintaining high test speed with increased RF testing complexity

Open RAN markets, opportunities, and challenges

Benetel has been an early pioneer in the disaggregated Open RAN ecosystem.

In this presentation Benetel’s CEO will provide his perspective on:

  • Open RAN’s progression
  • the opportunity for innovative players in this emerging market

Open RAN solutions for lab and field

With the technical evolution and motivation of Open RAN, radio access networks (RANs) are made open, disaggregated, and intelligent. Opening the network architecture can foster innovation, accommodate customized deployment needs, and enhance network efficiency.

The O-RAN ALLIANCE defines new O-RAN interfaces complementary to 3GPP RAN interfaces and additional specifications. Standardization of interfaces allows a mix and match of vendors for network components. However, it also brings new testing challenges and test solutions play an even more critical role compared to traditional RAN testing.

This presentation covers:

  • a discussion of the testing challenges for network components due to disaggregation
  • a demonstration of fully integrated O-RAN test solutions for lab testing

Testing next generation infrastructure equipment in production

The 5G radio access network has evolved to enable equipment compatibility between suppliers, paving the way for both more (new) infrastructure suppliers, and increasing the stimulus for more innovation in network infrastructure. Many infrastructure equipment manufacturers are introducing comprehensive digitalization of processes and data in production plants, aiming to improve quality, efficiency, and productivity. Successfully reducing the cost of test for modern macro base stations, small cells and repeaters will be critical, especially for new entrants in the mobile radio infrastructure market.

This presentation covers:

  • a discussion of the challenges for testing infrastructure equipment in production
  • a demonstration of compact test solutions ideally suited for production floors

Critical design considerations for massive MIMO

As demand for mobile data continues to grow, technologies such as Massive MIMO and beamforming have become critical to increasing cellular network capacity.

This presentation covers:

  • the critical design challenges of existing Massive MIMO radios
  • future challenges in the journey towards 5G Advanced and 6G

Base station testing from FR1 to sub-THz

This presentation covers:

  • RF-related challenges confronting designers of next-generation base stations and end-user devices
  • the heightened signal-to-noise ratio requirements due to increased modulation order
  • testing needs in the sub-terahertz region
  • anticipated potential obstacles in the emerging FR3 region
Maintaining high test speed with increased RF testing complexity

Maintaining high test speed with increased RF testing complexity

Future RF tests are getting more complex. Classic approaches such as sequential processing of large data sets are limited in their scalability.

This presentation covers:

  • Rohde & Schwarz Server-Based Testing (SBT), a novel approach based on massive parallelization of processing that significantly reduces overall testing time
  • use cases highlighting the benefits of SBT and where this approach complements traditional instrument-based measurements
