Understanding Plenum and other NEC Cable Ratings

Today marks the beginning of a new way to think about the future of manufacturing. The 5G Innovation Zone is located in Samsung Austin Semiconductor, one of the most advanced semiconductor fabrication facilities in the world. As would be expected in a smart factory, the Innovation Zone is designed to leverage a combination of multiple connectivity technologies, including 5G, LTE, and Wi-Fi.

The most important promise made by the proprietors of 5G wireless technology -- the telecommunications service providers, the transmission equipment makers, the antenna manufacturers, and even the server manufacturers -- is this: Once all of 5G's components are fully deployed and operational, you will not need any kind of wire or cable to deliver communications or even entertainment service to your mobile device, to any of your fixed devices HDTV, security system, smart appliances , or to your automobile. If everything works, 5G would be the optimum solution to the classic "last mile" problem: Delivering complete digital connectivity from the tip of the carrier network to the customer, without drilling another hole through the wall.

Intelligence at the Edge Part 3: Edge Node Communication

Connected industrial machines can sense a wide array of information used to make key decisions within the Industrial Internet of Things IIoT. A sensor within an edge node can be spatially far removed from any data aggregation point. It must connect through a gateway that links edge data with a network. Sensors form the front-end edge of the IIoT ecosystem.

When you run cable through any building you first need to consider plenum spaces. Plenum spaces are the open spaces above the ceiling or below the floor that are used for air circulation. Technically, any ductwork is considered a plenum space too. These spaces are important for air circulation in any building, but they also bring some problems if you ever have a fire because of the high oxygen content and lack of fire barriers. Using untreated cables in plenum spaces can spread the fire to other areas very quickly and spread noxious smoke throughout the building.

Николь пребывала в смятении. Периоды долгого молчания прерывались потоками явно нелогичных вопросов. Так, ей пришло в голову спросить, почему у одних Узлов четыре модуля, а у других - три. Орел объяснил ей, что добавляется Модуль Познания, примерно к каждому десятому или двенадцатому Узлу. Тогда Николь захотела узнать, чем именно характерен Модуль Познания.

Орел ответил ей, что в нем скапливается вся информация об этой части Галактики.
