Comparison of Indoor Propagation Modeling of WiFi Coverage Using Wireless InSite and Measurements

2014-07-25 16:11:39| rfglobalnet Downloads

Modeling radio frequency transmission coverage in complex indoor environments requires high-fidelity 3D models and advanced electromagnetic calculations. The 3D ray tracing code in Wireless InSite can accurately predict received power coverage even in a multi-room environment containing many walls and different material types. In order to verify the accuracy of the code, the floor plan of Remcom’s business offices was modeled in the software with a WiFi antenna. We then used a third party tool and a laptop computer to create a coverage plot of the received power throughout several of the suites. In this presentation we present the results for this basic measurement campaign.

Researchers identify possible glitch in Antarctic ice measurements

2014-07-23 17:39:00| Climate Ark Climate Change & Global Warming Newsfeed

Ars Technica: With all the attention given to every nuance of climate data, areas of research that would have never attracted much public interest sometimes find themselves in the spotlight. So it is with the process of measuring sea ice cover. People pay careful attention because it appears to be a leading indicator of climate change. In the Arctic, where the warming has been most intense, sea ice is retreating rapidly, with record lows having been set every few years over the past decades. But at the other...

CO2 Transmitters obtain clean measurements via NDIR procedure.

2014-07-18 14:56:39| Industrial Newsroom - All News for Today

Able to accurately measure CO<sub>2</sub> concentrations up to 10,000 ppm, EE850/EE820 series apply dual wavelength NDIR (non-dispersive infrared) procedure that is insensitive to pollution. Also, autocalibration function automatically compensates for aging effects. Multi-point CO2 and temperature factory adjustment procedure leads to optimal CO2 measurement accuracy over entire working temperature range, and measured values are available as analog current or voltage outputs.

Multi-Gauge Controller displays 10 pressure measurements.

2014-07-09 14:30:58| Industrial Newsroom - All News for Today

Providing pressure measurements from 1,000 Torr to 2 x 10-11 Torr, Model MGC4000 can display measurements from up to 10 different vacuum gauges simultaneously. Instrument can be configured to display up to 6 gauges in single screen or any number of gauges can be assigned to various screens for auto scrolling of display. By specifying number of gauges, set points, and AI/AO they require, customers can configure MGC4000 to exact specifications.
