A Windows based PC Program developed to assist the Radio Engineers in designing Point to Multipoint 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.

• To Calculate Receive Label and Outage for various MW Links. The Calculation is based on the Latest ITU-R recommendations and incorporates the factors for XPIC working as well as Space diversity improvement.

• To Calculate and incorporate Diffraction loss in outage calculations, Diffraction losses are also calculated in accordance with the latest ITU-R Recommendations.

• 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 the variation in K Factors and Antenna height.

• To Calculate over reach interference for long distance MW Links MS EXCEL based "OVERREACH" is supplied free of Cost.

• Extensive Reports Tabular as well as Graphical can be generated.

• Context Sensitive help

RADIANT Ver 4.1

A Windows based integrated interference calculation and analysis tool primarily meant for assisting Major Wireless users and SACFA clearance applicants on their own system and accord clearance or otherwise. The tool verifies the following :-

• Co-channel/Adjacent-Channel Radio interference likely to be caused by the incoming applicant to any of the SACFA members own site. he applicant could be a Microwave Link facility, Earth Station or a Fixed station facility.

• Calculate interference between SACFA members own installations and another set of installations.

• Any physical obstruction likely to be caused by the incoming Applicant to any of the SACFA members Links.

• Automatically calculates and confirms Distance and bearing to the nearest Airport.

• Generation of extensive reports including a graphical display of the incoming site w.r.t the SACFA members own sites with in specified distance of that location.

• Generation of NOC (no objection certificates) subject to the clearance of Interference and LOS obstructions.

• Context Sensitive help
