As high-bandwidth requirements continue to rise over the last few years, multiple system operators (MSOs) transform their hybrid fiber/coax (HFC) networks. Available architectures, such as DOCSIS 3.1 and Remote PHY, rely on fiber-based bandwidth deep into the cable television (CATV) network, which is why countless operators aim to create Node+0 architectures via “fiber deep” initiatives.  […]

There has been no doubt that fiber networks ensure the viability of smart-device applications, video streaming, and business requirements. However, with a demand increase, it only makes sense for service providers to continue striving for improvements in broadband access networks, which will require several tests on different network parameters, namely insertion loss, distance, and optical […]

Timing and synchronization is everything in 5G For a mobile network operator, timing is everything. Not just determining when to upgrade the network to bring new services to market, but in the literal sense as well. If the radio clock loses synchronization accuracy in a radio access network (RAN), or the radios are out of […]

At the moment, China currently sits at the top of the world standings when it comes to the number of 5G towers successfully installed. However, even with 600,000 5G towers and base stations installed throughout the country, it has only touched the surface of complete 5G penetration, as the country will need up to 10 […]

In an increasingly digital world where every pillar of information is now online, lightning-fast connectivity, rock-solid reliability, and impenetrable security are transforming into essentials within the network industry. 5G transforms the connected ecosystem and pushes the boundaries of connectivity to lay the foundation of a faster, more secure, and sustainable future.    For years, if […]

RAN Intelligent Controller

RAN Intelligent Controller At the O-RAN Alliance Plugfest at the end of last year, VIAVI, alongside partners AT&T, Samsung and Nokia, demonstrated an end-to-end traffic steering use case based on a number of open source components. One of these was the near real-time RAN Intelligent Controller platform, or RIC. Central to the demo was VIAVI’s […]

Understanding RAN  The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower. The hardware and communication interfaces are owned by a specific vendor, and its software-driven functionality is tightly […]
