Telecom operators need to reduce development time and while implementing new solutions to increase the performance and reliability of 5G networks in a cost-effective manner. Operators have already implemented open systems in their network cores and virtualizing functions, and now they want to achieve the same benefits with RANs including Radio Units (RUs). The Open RU (O-RU) roadmap covers both traditional macro radios and Massive MIMO and addresses key challenges including overall design cost reduction and accelerated time-to-market without sacrificing system-level power and performance. This panel will discuss the key digital, analog, and RF technology considerations that will enable radio ODMs, CMs, and System Integrators to offer flexible and scalable end-to-end RAN solutions.
