How can we build trust in the Open RAN ecosystem? As 5G demand continues to escalate worldwide, Mobile Network Operators (MNOs) are seeking ways to improve performance, speed new services to market, and increase agility, even as they cut operational costs. These demands are driving interest in virtualized and open Radio Access Network (RAN) architecture

Baud rate in optical transceiver In a coherent transmission system, you control two parameters: the Quadrature Amplitude Modulation (QAM) and the moderate. However, the QAM is limited. As you increase your QAM density from Quadrature Phase Shift Keying (QPSK) to 8 QAM, then 16 QAM, and 32 QAM, you reduce the tolerance to noise, which

Why do you need network modernization? A new article in Pipeline Magazine explores the evolving landscape of network infrastructure and the imperative for modernization driven by automation and optimization techniques. The article emphasizes the increasing complexity of modern networks, fueled by the increase of devices, applications, and data traffic. This complexity presents significant challenges for

In the last few years, I have noticed changes among our tier 2 and 3 FLASHWAVE 9500 conventional ROADM customers regarding how they are thinking about network evolution and modernization. The FLASHWAVE 9500 has formed the foundation of their network for over 15 years now, and while it’s a great choice for transporting traffic up

To successfully deploy and operate Radio Access Networks in a complex, heterogeneous environment, new management tools and methodologies are needed at all phases of the network lifecycle. The O-RAN Alliance defines aspects of network control and AI in its architecture. I’m Blake Hlavaty, here for an open dialogue about the value and impact of the

The evolution of optical network technology continues to move toward ever greater infrastructure disaggregation, and for good reason. Open optical networks allow communications service providers (CSPs) and data center operators to mix and match components from different vendors, avoiding proprietary vendor lock-in to speed innovation, increase agility and reduce total cost of ownership (TCO). Yet,

Lab-as-a-Service for Open RAN As the telecommunications industry continues to adopt Open RAN, there is a growing need for testing and validation facilities that can streamline the deployment of multivendor solutions. The VALOR (VIAVI Automated Lab-as-a-Service for Open RAN) lab, which officially opened its Chandler, AZ facility in October 2024, brings together a diverse ecosystem

Put BEAD funding to work for your broadband deployment project What’s the biggest challenge in broadband deployment? According to small and mid-sized operators, their top concern is the workforce shortage. There aren’t enough skilled people to fill the 150,000 to 205,000 jobs that BEAD funding is expected to create in the US. If the lack

Take the first step in network transformation with network modernization Technology evolves exponentially. The lag time between disruptive innovations—which gives network managers time to adapt and catch up—is growing shorter. As a result, many Communication Service Providers (CSPs) may feel like they’re falling behind. Network transformation has become an important strategy for CSPs who want

The mobile network landscape is undergoing a significant transformation, moving away from single-vendor, closed solutions towards open standards-based ecosystems. This shift, driven by the desire for increased flexibility, cost-effectiveness, and innovation, is leading to the widespread adoption of Open Radio Access Network (Open RAN) technologies. Within this evolving environment, open radio management emerges as a

Using dApps for real-time control and management The Open Radio Access Network (Open RAN) ecosystem is undergoing a radical transformation driven by the need for more efficient, flexible, and intelligent network management. Central to this evolution are the RAN Intelligent Controller (RIC) applications, including rApps, xApps, and the newly emerging dApps. These applications serve distinct

As a product manager leading the development of network digital transformation solutions, I’m fascinated by the potential of the Near-Real Time RAN Intelligent Controller (Near-RT RIC), which provides near real-time control and optimization. This capability brings intelligence and unlimited possibilities to the radio access network (RAN). But what exactly is a Near-RT RIC, and how
