Part 2 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 3: CPRI ) As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the […]
Packet Pioneer Chris Greer reveals his own Wireshark nightmare while dealing with trace files in the popular analyzer. “I’m a big user of Wireshark,” says Chris Greer, network and application analyst and founder of Packet Pioneer. “I own and operate an independent consulting company. What I do is I sit on the beach in Costa […]
Rolling out DOCSIS 3.1 alone will not be enough to meet long-term subscriber bandwidth demands, which is why many operators are linking their DOCSIS 3.1 rollout with the migration to distributed access architectures (DAA) like Remote PHY. To learn more about how VIAVI can help simplify your transition to Remote PHY, download our new solution […]

A shift to cloud computing may appear to offer great relief but it also delivers a host of new network challenges. Through cloud computing, organizations perform tasks or use applications that harness massive third-party computing and processing power via the internet cloud. This allows enterprises to quickly scale services and avoid purchasing network assets for […]
With intellectual property, customer data, trade secrets, employee information, and more traversing the network, IT teams need to be aware of the latest network trends – and how to monitor them. One of the most important assets to an enterprise is the network. If the network is not directly responsible for revenue, why even have […]
Plug-and-play technology has been around for a long time, and it’s one reason why even non-tech-savvy consumers can upgrade and expand their own electronics. We all like plug-and-play capabilities because it’s a fast, easy way to activate a new capability. As the name says, just make the connection and you’re ready to go. The beauty […]
Fronthaul? Until few years it was unknown for most involved in network deployment. Smart phones, the explosive growth in use of media reach apps and the competitive pressure for operators to offer higher data limits have changed the role of fronthaul completely. One can hardly oversee the rising number of antennas and radios mounted on […]
