What are the challenges for Open RAN deployment?
Challenges of Deploying and Managing O-RAN based networks
Interoperability and end-to-end performance will be by far the biggest concerns on the minds of vendors and operators in an O-RAN environment. Imagine all the advanced coordination features, power control algorithms, and intra-technology interactions in a multi-vendor RAN. Today, having one vendor simplifies all that. And, when product-related network performance issues arise, which is inevitable, service providers work with only one vendor to resolve them.
Now imagine a network where RAN components such as central unit, distributed unit, and radio unit are supplied and supported by multiple vendors – operators and vendors will face greater challenges in both identifying and isolating issues as well as ensuring that performance/cost compares favorably to that of an optimized single vendor solution.
Another key challenge of an O-RAN-based multi-vendor network will be network management and resource management. Management of multi-vendor spares and training resources to maintain a multi-vendor network will be a learning curve for service providers’ operations teams. Not to forget, integrating new functions and orchestration of new services from various vendors in an O-RAN-based network will be another key challenge.
To overcome the above challenges, O-RAN ALLIANCE has been working with its members and contributors, including VIAVI and AMDOCS, to deliver a reference architecture designed to enable next-generation RAN infrastructures. This reference architecture will be based on well-defined, standardized interfaces to enable an open, interoperable supply chain ecosystem in full support of and complementary to standards promoted by 3GPP and other industry standards organizations.
In short, the challenges for deploying and managing an Open RAN solution
- Integrating and ongoing management of the complex multi-vendor Open RAN solution
- Validating the interoperability of the multi-vendor RAN components
- Orchestration of multi-vendor RAN components
- Accountability for issue resolution
- Ensuring the network performance is comparable to an optimized single vendor solution

5G for Smart Healthcare & Public Safety
Private cellular might be the marquee network technology among today’s 5G advances & Network Convergence should provide a boost to it in 2022. But the tool has different flavors and architectures for taking advantage of new opportunities to inform the larger deployments and in shaping their respective ecosystems. Learn what is the “just right” mix.
The 5G trends and technologies in 2021 and predictions for 2022 from Neil McRae, Managing Director, and Chief Architect at British Telecom. Some of the key trends of 2021 include private networks, edge computing, Open RAN, swapping vendors driven by security concerns (i.e. clean network), keeping networks up in the Covid-19 pandemic, and rolling out 5G and 4G networks.
