The current Wi-Fi standard, 802.11ac, works very well in a home environment. However, as with previous Wi-Fi standards, it may reach its limits around 2022 when there could be up to 50 nodes in a home. The 802.11ax network is the next evolution in the IEEE 802.11 Wi-Fi standard and will become prevalent in very dense environments, such as urban apartment complexes, college campuses, concert venues, or sports stadiums, where many clients will access the internet over Wi-Fi. This article presents five key aspects of the new 802.11ax network and the next generation of Wi-Fi.
The roadmap for future military systems considers the fact that the amount of spectrum is finite and advanced militaries define their spectrum use and develop their systems using a very long procurement cycle. As a result, advanced militaries are moving to adopt a system of dynamic spectrum allocation, which involves the use of software defined radio combined with fielding agile systems and spectrum management practices. An impediment to this approach is that the current military procurement and system development effort takes many years. In the current procurement approach, the spectrum and electromagnetic environmental effects (E3) considerations are afterthoughts that are applied in a one-size-fits-all manner. To enable the next generation of military systems and fleet upgrades to operate effectively in the future of dynamic spectrum allocation, we must consider dynamic E3 and spectrum requirement during system development and procurement phases.
This article provides an example that details the setup and execution of RCS calculations using XGtd’s X3D PO MEC model and compares the predictions to those made using XFdtd.
Monolithic microwave integrated circuits (MMICs) based on high-power PIN diodes are increasingly used for many transmit/receive systems in advanced defense electronics and telecommunications applications. For such applications, switches are required to have microwave and mmW frequency capability, as well as the ability to handle high power levels, low insertion loss, good matching, and fast switching — and, for non-reflective switches, good return loss in “off” state.
FEKO, Altair’s comprehensive electromagnetic simulation software suite, can be used in electronic virtual prototyping and simulation driven designs, including antenna design for many products such as mobile phones, tablets, cameras, laptops, and TVs. The software can eliminate weak antenna designs and reduce the number of prototypes with its proof of concept and comparative studies. Pre-compliance of over-the-air (OTA) radiation performance and specific absorption rate (SAR) can be estimated for the standalone device, or for different usage environments.

This video demonstrates the antenna sets within Wireless InSite and walks users through the available options. Users will also learn how to assemble an antenna set and choose their antenna pattern. The video also covers Wireless InSite's visualization tools, which allow the user to see how their antennas are oriented within the antenna set.
This video introduces Wireless InSite's Floor Plan tools and shows the user how to create and edit an indoor environment. The demonstration includes the placement of walls, doorways, and windows, along with material selection from Wireless InSite's material database. In addition to the 2D floor plan editor, the video also demonstrates how to make edits within the 3D display.
This short animation shows predicted RCS from an air traffic control radar with an aircraft flying over a wind farm, before and after the static ground clutter (returns from terrain) are filtered out. A basic filter has then been applied to remove the portions of returns with 0-Doppler (static clutter from the ground and wind turbine towers) to approximate what a radar might see after attempting to filter out objects not in motion. Although actual radars have much more sophisticated signal processing, this basic before/after animation of RCS from subsequent scans shows the problem that standard Doppler filtering would encounter when processing returns from a wind farm.
