  1. Distributed Antenna System (DAS) For IoT, Cellular And Other Wireless Applications

    The Internet of Things (IoT) has continued to grow at a rapid rate in recent years. With the connectivity of more and more devices, it’s more important than ever that these devices can connect, communicate and meet the needs that users covet. Distributed Antenna Systems (DAS) are used to provide strong and reliable wireless connectivity in location where connectivity is a problem with standard wireless routers or cellular connectivity. This application note discusses the use of DAS for IoT, cellular and other wireless applications, and the benefits it can offer.

  8. What’s Best? Wi-Fi 6 (802.11ax) Or 5G?

    Every time a new cellular phone standard comes out, we see new claims about the “end of Wi-Fi.” When 3G was announced, the promise was that it would make Wi‑Fi (802.11b) redundant, which clearly turned out to be incorrect. With 4G (LTE), this story repeated itself and claimed it would put Wi‑Fi (802.11ac) in the shredder. And now the 5G message is that it will cover both the inside and outside of homes and buildings. It’s almost as though Wi‑Fi will soon no longer be needed. This begs the question: What will be the impact of the next generation of Wi‑Fi, Wi-Fi 6 (802.11ax)? Do we even need it in the 5G/wireless landscape? This article discusses the answers.

  9. White Paper: Modeling RF Propagation In Mines Using Wireless InSite

    This paper presents results from modeling RF propagation in a mine using Wireless InSite®. The Edgar Mine in Idaho Springs, CO provided the realistic scenario for the model. The path loss exponent was evaluated for a 5m section of the modeled mine by considering three different materials and three different standard deviation of surface roughness values for dry granite. When comparing this simulated data with data retrieved from the Edgar Mine it was determined that the Uniform Theory of Diffraction (UTD) ray tracing code, of Wireless InSite, can portray a communications system within a mine environment.

  10. White Paper: Complex 3D Modeling Of Sea To Land Scenario

    This paper presents results from sea to land propagation using Wireless InSite®. The effort explores the effects of various elements in the scene and how they impact the results. The various elements in the scene include the ships out at sea, the ships docked, the docks themselves, the buildings around the dock area, and the material properties of each.
