The endless potential of the 5G network is precisely what we need during these difficult times. Working remotely has become the “new normal”, but to say the experience has been smooth and seamless would be an exaggeration, as many still face issues when working from home, especially regarding connectivity. However, the 5G’s staggering prowess will […]
As module bitrates increased from 100Gbs so too did the complexity of the modules. Starting with DSP based signal conditioning and clock recovery and onwards to pluggable coherent optics, PAM-4 and CMIS. With this new level of complexity, we had to take a very different approach to module-to-pluggable optics development, debugging and validation. Specifically, the […]
The status-quo of early 2020 no longer exists for the corporate network. The pandemic threw a wrench into the architecture and network operations that businesses had relied upon. The ongoing transition has necessitated and accelerated changes for people, processes, and technologies. I recently took part in an executive roundtable with Bloor Research and members of […]
5G is introducing tight integration with satellites to expand high-speed coverage into hard-to-reach areas and support maritime applications. This presents a whole new set of challenges for satellite transceiver performance. Next-gen network deployments are ramping up around the world, but there is more to 5G than land-based New Radios and the new Packet Core. 5G […]
The ever-growing demand for higher and larger bandwidth, computing power, storage and speed capabilities in the modern age, not to mention constructing a seamless and secure cloud service, can only be fulfilled by a complete hyperscale ecosystem integrated with the 5G. This ground-breaking technology has been pushing the digital ecosystem by introducing more intelligence to […]
