Network convergence might sound like an enigmatic concept when, in fact, it’s simply the aggregation of all electronic mediums of communication onto one ubiquitous 5G network. In essence, it merges mobile, video transmission, data communication services into a coexisting network. The need for increased bandwidth in an always-online society is the motivation that has given […]
Full-fiber broadband is already on the horizon. In fact, the APAC region are ahead of the curve as Singapore reaches first place with 93% fiber coverage across the island. The rest of the world is following along with substantial investments into similar infrastructure across multiple countries. For example, the UK recently approved a £5 billion […]
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 […]
With the arrival of 5G already occurring in select countries and the anticipated launch expected to happen in most within 2020, the need for telecom engineers to be skilled and trained within all aspects of 5G is evident. In order to achieve set targets and for the roll-out of 5G to be deemed successful, telecom […]
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 […]
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: […]
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 […]
With so many KPIs and metrics for tracking security and performance over networks, clouds, clients, and applications, it’s difficult to see how SecOps and NetOps engineers ever rise above the noise. VIAVI Solutions takes a different approach to eliminate the noise and improve engineer effectiveness in solving issues. An example of this in Observer is […]
