Today’s mobile network operators face a more challenging set of decisions than ever before. For many years, frequency synchronization delivered by TDM-based technologies was sufficient for the timing demands of mobile networks. Then came the evolution to packet- and Ethernet-based networks, which required additional features, such as the ability to transport timing information in packets ...

Fixed wireless access (FWA) is experiencing a resurgence, as a growing number of operators in all regions of the world are leveraging their investments in mobile infrastructure (particularly 4G LTE and forthcoming 5G) to provide fixed broadband services. Why the resurgence? If one can recall, there have been two major industry attempts at this space. The first was wireless local loop (think LMDS from the late 1990s), but equipment was expensive and proprietary. The other major attempt was WiMAX, which never gained the promised market momentum or capabilities and was quickly overshadowed by a rapidly advancing mobile market with the introduction of LTE. But enough about the past …

Multi-access edge computing (MEC) is expected to play a strategic role as networks transform, bringing new levels of performance and access to mobile, wireless, and wired networks in support of future services and applications. A key goal of MEC is to reduce network congestion and improve application performance by moving functions, content and processing closer to the subscriber. By doing so, network operators will be able to better utilize network resources while also improving the delivery of content and applications to provide end users with a better quality of experience through lower latency and higher bandwidth ...

New cloud services, the internet of things and the evolution of mobile networks towards 5G are driving capacity needs in the metro to unprecedented levels. In an effort to overcome bandwidth bottlenecks, reduce cost and ensure scalability, more and more network operators are now turning to flex-coherent technologies. Total capacity and lowest cost per bit are two critical metrics in the metro. That's why software-defined, flex-coherent optics - which can efficiently carry 100G, 200G and even up to 600G of capacity on a single wavelength - are so important for metro applications ...
