George Jetson Meets Smart Buildings

There used to be a Saturday morning cartoon called The Jetsons.  It was very futuristic – and one of the noteworthy things in the series was the smart building George and his family lived in. A robot that took care of the household, an integrated jogging floor on the balcony, push-button TV screen that triggered machines to cook dinner, set mood lighting, activate mood music; windows that got darker or lighter, and so much more. Here in 2020, we are getting ever-closer to the George Jetson era.

How Ethernet Has Enabled Today’s Hyper-Connected World

One of the most important elements to the success of the Internet even from its earliest days nearly 40 years ago is Ethernet. Bob Metcalfe, known as the Father of Ethernet, came together with peers to invent and develop the Ethernet local-area network (LAN) technology and its system of packet protocols. This allowed personal computers to efficiently share files and printers, a major advancement for its time.

Cable operators and edge computing: Where and why?

What do AR/VR, cloud gaming, smart cities, 5G, autonomous vehicles, healthcare sensors, surveillance and facial recognition all have in common? The need for low-latency connectivity enabled by networks architected with edge computing. For some service providers, edge computing trials have already started. For others, edge computing plans won’t be formulated for a few years. But, whether they’ve already devised their edge compute strategy or haven’t yet begun, the first question they need to ask themselves is: “How do we define edge computing?”

Understanding Fiber Optic Based Light Source

Using single mode fiber for short distances can cause the receiver to be overwhelmed and an inline attenuator may be needed to introduce attenuation into the channel. With Gigabit to the desktop becoming commonplace, 10Gb/s backbones have also become more common. The SR interfaces are also becoming common in data center applications and even some desktop applications.

OFC 2020 to Host Live Multivendor Technology Interoperability Demonstrations

OFC will feature multivendor interoperability demonstrations of the products and solutions enabling next-generation infrastructure. Technologies featured in the demos include: 400ZR, 400G Open ZR+, OpenROADM, Common Electrical I/O (CEI)-112G, FlexE, IC-TROSA, 10 Gigabit Ethernet (10GbE), 25GbE, 50GbE, 100GbE, 200GbE and 400GbE and 400G on-board optical modules.

Smart buildings and dealing with data overload

Over 80% of new builds now involve at least one aspect of smart technology such as smart security, lighting or controls, including new homes as well as commercial builds. But with all this smart technology potential, building owners and users are now faced with other challenges: data overload, confusion about choices of which technology suits their needs and the decisions they need to make for their return on investment (ROI) over time.

Smart Buildings – Taking Building Automation to the Next Level

Building automation, as a working discipline, has been around for ~ 30 years. By the turn of the century many buildings were equipped with computers/controllers that could connect to the internet and provide greater control over many building parameters (temperature, lighting, access, security, etc.). Those buildings could be considered “automated” but they were not “smart”. Smart buildings are the next phase of this evolution. The Internet of Things (IoT), Artificial Intelligence (AI), and Machine Learning (ML) are combining to make buildings more dynamic, more adaptive, and more efficient. This article addressees the current challenges faced by building operators and facility managers and how emerging technologies can address these challenges.
