  • The Essential Signal Generator Guide Building A Solid Foundation In RF – Part 1

    Selecting the right testing instrument for a project is essential to get products to market faster. This is Part 1 of a two-part white paper discussing signal generators. This paper offers an overview of the fundamentals of signal generators, enabling users to make the right decision when selecting one for different applications.

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.

CWDM vs DWDM: What’s the Difference?

 A great deal of confusion exists surrounding RF over fibre via coarse wavelength division multiplexing (CWDM), or dense wave division multiplexing (DWDM). This article aims to clarify the differences between the two methods, as well as discuss the challenges associated with both technologies.

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.

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.
