This interview discusses the evolution of network optimization technologies. Per Kangru, Strategy Director, VIAVI Strategy Office delves into the transition from Self-Optimizing Networks (SON) to the promising RAN Intelligent Controller (RIC). Can you explain why SON was considered a significant development in the first place? When SON, or Self-Optimizing Networks, emerged, it was a […]
While evaluating high-speed network test equipment, it may be tempting to forgo deep physical layer testing capabilities to save money and reduce testing complexities. In some cases, these ‘just good enough’ solutions appear to fit the bill, but lack of deep insights can lead to product re-designs, longer development cycles or systemic failures in the […]
3GPP Release 18, what is it? 3GPP Release 18 is the 4th release of 5G and recognized as the first release of 5G Advanced. Overall, it marks the mid-point of 5G standardization. Significant Updates from Release 17 5G Non-Terrestrial Networks Work was carried out in Release 17 to define the first standardized solutions for 5G […]
Since the emergence of 400 Gigabit Ethernet (GbE) around 5 years ago, we have seen PAM-4 modulation replace NRZ on both optical and electrical interfaces. We now see a broad and healthy ecosystem building for 400 GbE, and even 800 GbE, using PAM-4 signaling. In fact, we are even seeing the first 100 Gb per […]
Reducing TCO and optimizing energy use in next generation RAN demands a superior level of network intelligence. Operators are increasingly concerned about rising energy costs. Additionally, they need to lower total cost of ownership (TCO) and ensure a positive return on investment (ROI) for their network upgrades amid growing competition and stagnant subscriber growth. 5G […]
Pluggable coherent optics really hit mainstream in 2022 and a big part of that was the multi-vendor ZR interop at the OIF booth at OFC 2022. It was great to be involved in this public event as we have been involved in the background for many years supporting the pluggable coherent ecosystem from the earliest […]
Transformative technologies such as edge computing, 5G, and mobile clouds are enabling bold and exciting new business models. Industry 4.0, autonomous vehicles, and remote medicine are just a few examples of the advances these technologies offer. Open RAN (O-RAN) is a key foundational framework poised to facilitate this revolution, allowing for rapid and widespread innovation […]
Technology is not disposable. Yet broken products or those that we deem obsolete to us are often discarded, and that’s bad for the environment. The scarce resources and energy used to produce the item is lost. If the product was passed on to someone else to use or, if unfixable, it was harvested for parts, […]
The proliferation of mobile devices and increasing demand for data usage has resulted in a large-scale expansion of wireless cellular networks. Operators need more and more cells to handle the increasing demand, but, it is hard to scale the infrastructure for mobile services in real time. You can’t build a new cell tower overnight therefore […]
A number of countries including China, the US, the UK, Spain, The Philippines and South Korea have already rolled out 5G in their cities. In the next few years, 5G is predicted to be available in almost every part of the developed world. There are high expectations of 5G performance from professionals and individuals who are anticipating […]
