5G on stage in Barcelona
By Brian Lavallee – The theme of this year’s event is “Intelligent Connectivity” – the term we use to describe the powerful combination of flexible, high-speed 5G networks, the Internet of Things (IoT), artificial intelligence (AI) and big data”. This clearly highlights that important fact that 5G is more than just a wireless upgrade. It’s also about updating the entire wireline network from radios to data centers, where accessed content is hosted, and everything in between.
This means the move to broad 5G-based mobile services and associated capabilities will be a multi-year journey requiring many strategic partnerships.
The multi-year journey towards ubiquitous 5G services will understandably be the star at MWC, and rightfully so.
There remains uncertainty about what technologies and architecture should be used for specific parts of the end-to-end 5G mobile network, such as the often discussed (and often hotly debated) fronthaul space.
Early 5G mobile services are already being turned up in many regions in the form of early deployments, field trials, and proofs of concept. These services are delivered in 5G Non-Standalone (NSA) configuration, which essentially hangs 5G New Radios (NRs) off existing 4G Evolved Packet Core (EPC) networks. This allows for testing new 5G wireless technologies and jumpstarts critical Radio Frequency planning and testing.
It also means that most new wireline upgrades that are taking place now for 4G expansion and growth will also carry 5G wireless traffic to and from data centers. more>

Ciena unveils WaveLogic 5: 800G and so much more
By Scott McFeely – Today is an exciting day at Ciena, as we have unveiled the next generation of our WaveLogic coherent technology – WaveLogic 5. Introducing the next member of our WaveLogic family is not something we take lightly, because as my friend and colleague Dino Diperna says, “If we aren’t pushing technology to the boundaries, then we’re not delivering the optimal solution for our customers.”
So it’s not surprising that Ciena is once again raising the bar in coherent optical technology by providing the scale, flexibility and intelligence that solidifies our position as a leader in optical networking and your trusted partner for building the Adaptive NetworkTM. And we aren’t just coasting on our past successes. With WaveLogic 5 we are introducing two new solutions that can deliver coherent technology however our customers need it – from integrated systems to pluggable form factors – addressing the complete set of technical and economic requirements they have across a range of network applications.
There is a lot to unpack in today’s announcement, so let’s start by addressing the 800-pound gorilla in the room…do network operators really need 800G?
The answer is a resounding YES.
Our customers are responsible for providing the foundation of society’s digital lifestyle, and that requires moving massive amounts of data around the world – at the speed of light. While these challenges are not new, they are becoming more acutely felt. The pressure to deliver new revenue opportunities while cost-effectively supporting increased traffic demands is forcing providers to evolve and transform their optical networks. more>

By Sarah Garfinkel – When considering the senses, we tend to think of sight and sound, taste, touch and smell. However, these are classified as exteroceptive senses, that is, they tell us something about the outside world. In contrast, interoception is a sense that informs us about our internal bodily sensations, such as the pounding of our heart, the flutter of butterflies in our stomach or feelings of hunger.
The brain represents, integrates and prioritizes interoceptive information from the internal body. These are communicated through a set of distinct neural and humeral (ie, blood-borne) pathways. This sensing of internal states of the body is part of the interplay between body and brain: it maintains homeostasis, the physiological stability necessary for survival; it provides key motivational drivers such as hunger and thirst; it explicitly represents bodily sensations, such as bladder distension.
But that is not all, and herein lies the beauty of interoception, as our feelings, thoughts and perceptions are also influenced by the dynamic interaction between body and brain.
The shaping of emotional experience through the body’s internal physiology has long been recognized. The American philosopher William James argued in 1892 that the mental aspects of emotion, the ‘feeling states’, are a product of physiology. He reversed our intuitive causality, arguing that the physiological changes themselves give rise to the emotional state: our heart does not pound because we are afraid; fear arises from our pounding heart. more>
