PATHLINK Ver 2.0 (View Screenshot) Download PDF Pamphlet. BNN Infotech Engineers 'PATHLINK' is windows base PC Program developed to assist the Radio Engineers in designing Point to Point Radio Links. It uses well assessed procedures for Radio Link Design, with close reference to guidelines and propagation models recommended by ITU-R (formerly CCIR). In particular the tool provides following features:- To Calculate the Tower heights/ Antenna Heights for various frequencies by feeding path profile for working Line of Sight(Viewscreenshot). To Calculate Receive Level and Outage for various Microwave links. The calculation is based on the latest ITU-R recommendations and incorporates the factors for XPIC working as well as Space Diversity Improvement (Viewscreenshot). To calculate and incorporate Diffraction Losses in Outage Calculations. Diffraction Losses are also calculated in accordance with the latest ITU-R Recommendations. (Viewscreenshot). To Calculate the Reflection Point for a combination of Antenna Heights and study the variation of resultant field strength of the Main and Reflected signals with variation in K factor and Antenna heights To incorporate Rain Rates based on data specially produced by Indian Meteorological Department, specific to the indian Subcontinent. To automatically calculate the distance to the nearest Airfield ARP, as referred from the built in Airfield Database. (Viewscreenshot). Automatic preparation of SACFA Clearance forms Extensive Reporting and Printing Capabilities. Download PDF Pamphlet.
