Every day, professionals across a range of industries rely on radio communications using Land Mobile Radio (LMR) technologies, including digital mobile radio (DMR) systems. Whether a routine communication or a mission-critical emergency call, each transmission requires reliable and resilient technology. Radio test solutions play a critical role in ensuring that reliability and performance. Today, VIAVI […]
Tag – You’re It! Signal Tags and Their Use in Cable Signal Leakage Detection Cable signal leakage technologies have been around for more than three decades, and while the underlying concept of detecting CATV signals leaking out of the network has not changed, the technologies to accomplish this have changed considerably. Shortly after the first […]
The promise of 5G deployment has transitioned from the drawing board to reality as the 5th generation of wireless technology, planned and developed for nearly a decade now, begins limited service. The race is on to secure global 5G leadership due to the number of competitive advantages that are set to follow in tow. With […]
Tune In – Antennas are the Eyes and Ears of Signal Leakage Systems Despite huge improvements in computing power available to design tools and simulations, RF antenna design remains at least somewhat of a black art. The best antenna designers are often brilliant Engineers, but most will admit that past experience and quite frankly luck […]
The TDR (Time Domain Reflectometer) has been used in cable networks as an effective tool to find faults for decades. So why consider changing anything? If it isn’t broke don’t fix it, right? As TDR instrument development has been neglected, there is now an opportunity for improvements as can be seen in these points: Any […]
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: […]
Software-defined WAN is not just a service, but a new way of doing business. What’s old is new again ☺. Software-defined anything has a tendency to bring technology cycles back to life… remember SDN? Software-defined WAN is not just a service, but a new way of doing business. SD-WAN transformation is required – for service […]
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 […]
