The switch needs to be connected to the WAN port

The WAN port links your router to the internet or another wide area network. It keeps local traffic inside your network and sends outbound traffic to the WAN only when needed. If you use the DSL port, then you won't need to. When a router's WAN port is not working, the real challenge is not just restoring connectivity—it is determining why the failure occurred and what decision should follow. A WAN outage can be caused by upstream connectivity, configuration errors, or a physical interface failure. [pdf]

Handheld Comparison of Spectrum Analyzers for Smart Buildings

Handheld Comparison of Spectrum Analyzers for Smart Buildings

This guide highlights five top models that cover broad frequency ranges, robust signal generation capabilities, and practical data logging features. Each entry includes key specifications, practical use cases, and a quick buying guide to help you compare options for on-the-go RF. A Spectrum Analyzer is an instrument that allows you to measure, analyze and visualize RF signals. These instruments are used by hobbyists, academics and professionals alike. Applications for spectrum analyzers include manufacturing, education and amateur radio among other things. At Sonoran Surplus, we have a strong reputation. The screen visualizes them in a graphic of amplitude vs frequency. [pdf]

Energy-saving cost of handheld light sources for smart buildings

Energy-saving cost of handheld light sources for smart buildings

Energy savings of between 35 and 70 per cent on total lighting costs can be achieved with intelligent illumination. The convergence of building information modeling (BIM). Buildings are responsible for approximately 40% of global energy consumption, putting pressure on the construction industry to mitigate its environmental impact. According to ASSIL (the Italian Association of Lighting Manufacturers), the use of intelligent lighting can cut energy. This study conducts a scoping review of energy-saving research on smart lighting systems in office buildings to determine the field's scope, the primary technologies and methods employed, specific energy-saving outcomes, and existing research gaps. An efficient lighting-controlling system can significantly reduce the mentioned costs. [pdf]

Fiber optic cable spiral tube IK10 vs copper cable

Fiber optic and copper cables are built with very different materials, and as such are used in different circumstances for different tasks. Fiber optic cables are built with a silica glass fiber core, about the width of a. [pdf]

Switch Group Architecture vs Passive Optical

Switch Group Architecture vs Passive Optical

A passive optical network (PON) is a telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the between (ISP) and their customers. In this use, a PON has a topology in which an ISP uses a single device to serve many end-user sites using a system suc.
