Traditional spectrum analyzers display signal frequency and power level but provide no spatial correlation to the physical environment. Following an RF interference alarm, standard protocol dictates that an RF technician walks the site, takes multiple measurements, and makes an educated guess based on the available data to assess the emitter’s location. These best guesses are […]
Quantum computing poses a serious threat to current encryption standards, driving organizations to prepare for the post-quantum era. In this blog, we outline how rising risks are reshaping testing, performance planning, and cryptographic transition strategies. Why Today’s Encryption Isn’t Ready for Tomorrow Encryption has long safeguarded data privacy, with algorithms like RSA-2048 built to resist […]
It is rush hour in a busy city center. Thousands of smartphones are moving between cells as commuters leave offices and head home. Across the network, an AI-powered xApp is making real-time decisions about which radios can be powered down to save energy, and which need to remain fully active to handle demand. These decisions […]
Hollow core fiber (HCF) is rapidly transitioning from lab research into field trials and early operational deployments. Its ability to guide light through a predominantly air‑filled core rather than solid glass enables tangible performance gains, most notably lower attenuation, reduced latency, and less signal distortion. These properties make HCF especially attractive, particularly for data center […]
As cloud, AI, and high-performance compute environments scale, the physical media inside the data center is undergoing a fundamental shift. Traditional duplex fiber architectures are being rapidly replaced by multifiber connectivity, driven by higher speeds, denser architectures, and the relentless growth of east-west traffic. While this shift unlocks massive performance gains, it also introduces new […]
Distributed Acoustic Sensing (DAS) has become a critical tool for monitoring and protecting infrastructure at scale. As deployments have grown, so too have the expectations to move beyond simple detection toward higher accuracy, better event identification, and fewer false alarms. This evolution has driven the adoption of phase‑based DAS, such as VIAVI’s patented true‑phase DAS, […]
As we recently announced, VIAVI and NTT DOCOMO INC. have successfully completed a joint study demonstrating AI-driven radio access network (RAN) control for next-generation 6G mobile communications. The demonstration was conducted in a simulated environment modeling multiple base stations around the Tokyo Station area. Predictions were enabled by the TeraVM AI RAN Scenario Generator (AI […]
January arrives with a different kind of energy. The decorations are packed away, our stomachs have had their pick, pace is steadier, and the attention starts turning from celebration to intention. It is also the time for fresh starts and setting the foundation for what comes next. In this spirit of renewal, TDC NET enters […]
VIAVI has always been present at major inflection points across technology – and 2025 was no different. As we continued to engage with and support the telecommunications industry around the globe, we also reinforced our leadership in the data center ecosystem, aerospace, defense, and security sectors. In this blog, we review some of the breakthroughs from […]
Networks strive to enable both high throughput and low latency. However, as the number of packets moving through a given network reaches their limit, queues start to build, with delays/ congestion introduced as a result. Congestion therefore needs to be managed but legacy mechanisms for detecting congestion rely on packet loss as a measure that […]
