Smart buildings and wellbeing: Wearing your heart on your HVAC

How long before your building “knows” more about you than you do yourself? As ever-more processing is crammed into smaller, lighter and cheaper devices, it was only a matter of time before people would be able to wear them as they go about their everyday lives. It hasn’t taken long for people to find ways in which wearables could be used to improve the inter-relationship between buildings on the one hand, and the people who live or work in them, or visit them.

Optical Sensors are the Key to Health-Monitoring Wearables—And Size is Critical

One field that has benefited from optical sensor technology is wearable health and fitness. Optical biosensors have been embraced by the healthcare industry because they offer many advantages over conventional analytical techniques. This technology has appeared in applications including glucose sensing, laminate cure analysis, protein analysis, dosage form analysis, and many more.

PoE Cabling Explained: Architectures, Advantages, and Applications

Power over Ethernet (PoE) is shaping the current network ecosystem. Be it digital transformation, Internet of Things (IoT), NextGen wireless, smart devices solutions, etc. are all in rapid growth with the adoption of PoE technology. The structured and converged PoE cabling also has evolved in the past decade. This article explains common PoE cabling architectures, and provides further insights into the benefits and the applications of the zone cabling in PoE deployments.

5-port industrial 802.3bt PoE switches target harsh environments

Antaira Technologies’ new LNP-0500G-bt and LNP-0500G-bt-24 switches fulfill the need for low port-count PoE gigabit connectivity in industrial applications. Each unit has five gigabit Ethernet ports that are IEEE 802.3af/at/bt compliant on four of the ports (data and power output maximum 90W/port). The LNP-0500G-bt Ethernet switch is billed as rugged, reliable and geared for applications that require up to 90 watts of PoE power.

Ethernet Alliance ‘PoE Survey’ infographic reveals deployment insights

The Ethernet Alliance’s recent Power over Ethernet (PoE) product certification survey reveals some 78 percent of respondents experienced difficulties with PoE deployments — but that 72 percent expect noticeable improvement with products certified through the Ethernet Alliance’s PoE Certification Program. Further findings from the survey are available in a newly released infographic, available at: https://bit.ly/EA-PoEInfographic2020.

What is power over Ethernet (PoE)?

PoE is the delivery of electrical power to networked devices over the same data cabling that connects them to the LAN. This simplifies the devices themselves by eliminating the need for an electric plug and power converter, and makes it unnecessary to have separate AC electric wiring and sockets installed near each device. PoE’s use has grown substantially since the IEEE standardized it in 2003. Dell’Oro group says that PoE port shipments will total over 624 million over the next five years.

Testing Plug-Terminated Links—Internationally

The Modular Plug Terminated Link, or MPTL, where a horizontal cable run terminated on one end to an RJ-45 plug connects directly into a device, has become increasingly popular for connecting a variety of devices—from wireless access points and security cameras, to PoE lights and video displays—essentially wherever it’s deemed impractical or unsafe to deploy an outlet and equipment cord. Approved within ANSI-TIA 568.2-D as an option for connecting devices, MPTLs aren’t just popular in North America. But some of you have asked about regions that don’t follow TIA standards, and if it possible to test an MPTL to ISO/IEC or CENELEC standards. While the short answer is “not yet,” you can still make sure your MPTLs will perform.
