A Software Tool For Analyzing Radio Frequency Interference

WirelessSite-RFI (Radio Frequency Interference) is an authoritative, wireless communications site interference analysis tool. It is specifically designed to help identify, analyze, locate and resolve radio frequency interference that could affect the safe and efficient operation of wireless communications systems.

WirelessSite-RFI has been the Industry's leading RF interference analysis tool for over 30 years.

WirelessSite-RFI will calculate isolation values required to prevent receiver performance degradation due to transmitter noise, receiver desensitization, transmitter and receiver produced intermodulation products, harmonics and transmitter spurious output. The program saves many hours of arduous manual calculations and table lookups and eliminates human calculating errors. Additionally, it will automatically calculate insertion and rejection loss values associated with filters and multi-couplers and determine antenna gain values based on actual antenna patterns.

WirelessSite-RFI includes several libraries of manufacturers' data for equipment, transmitter noise and receiver desensitization curves (duplex curves), antenna gain patterns, and filter/multicouplers devices. The user can also create new RF component curves for any filters, radio equipment duplex curves that may be required as well as import additional antenna pattern files into the library.
