Why Signal Leakage, Why Now? Ingress has been the single largest thorn in the side of cable operators since the advent of CATV plants, only to be aggravated by the introduction of two-way services. Despite decades of innovation, the silver bullet solution to fully address this problem remains elusive. Why Ingress Is Such a Challenge: […]
When last we gathered around the soft glow of the monitor, we shared the oft-told tale of troubleshooting random user complaints and the importance of scoring and storing instead of ignoring. This time, let’s turn the pages of a related story – a fish story so to speak… In the rivers of data that flow […]
Day in, day out. You make a difference—connecting families, accelerating commerce, dispatching help—you diligently maintain and improve the networks and services that improve lives. Do you remember how you got here? The journey? All the hard work? We do… (sneak peek, if you can’t wait to the end of this post). Scrappy Underdog Think back, […]
It’s the tale as old as timestamps: A random user complains of a random performance problem When someone is available to assist the user, the problem is no longer occurring The available data doesn’t provide any real clues Wait a while. Repeat. Why is this story still being told? With all the advancements that have […]
Advancements in LiDAR (Light Detection and Ranging) system technologies are rapidly paving the road for intuitive self-driving systems. The push for automotive innovation does not come without addressing a unique set of challenges with functionality and safety at the forefront. As a leading manufacturer of high-performance optical filter technology for LiDAR systems, VIAVI Solutions has […]
The HFC Evolves Through the years, with the demand for additional speed and bandwidth cable systems have: Migrated from analog channels to 6 MHz SC QAM channels Migrated from modulation schemes from 16 QAM up to 256 QAM channels Migrated to DOCSIS 3.1 OFDM carriers consuming much larger areas of the spectrum Began migrating from […]
The Early Days of CLI Leakage The new regulations required the operator to monitor, measure with a specific technique, and log all system leakage. The operators soon realized that this was a difficult task with their current equipment, as signal level meters had insufficient sensitivity to measure 20 uV/m at even 10ft, much less be […]
Signal Leakage in Cable Networks, a Long and Winding Road Cable is a unique communications medium that has evolved from a rudimentary patchwork of transmission lines and components devised by an industrious group of technology pioneers decades ago into the leading broadband juggernaut that it is today. The remnants of this journey are still evident […]
It’s New Year’s Eve, the clock strikes midnight. You try making a VoLTE call to your friend to wish them well, but the call fails. WhatsApp is down, and your message doesn’t go through. At the very least networks should be able to handle 4G demands; the alternative is having to handle subscriber complaints and […]
The recent Capital One Cyber Incident provides us with yet another reminder of the dangers of becoming “cloud blind” as applications and data move to the cloud. Much has been written about the potential impact and cost of this cyberattack, but rather than focus on impact, let’s look at what readily available resources you have […]
