About this app

RF Path Profiler App provides professional-grade RF Path, RLOS, Fresnel Zone and Path Loss analysis using the Longley-Rice (ITM) radio propagation model. Designed for telecom engineers, RF planners, broadcasters, and wireless network designers, the app delivers highly accurate point-to-point link evaluation for frequencies ranging from 20 MHz to 20 GHz.

Whether you're planning microwave links, Wi-Fi backhauls, LOS radio links, or long-distance wireless communication, this app helps predict terrain impact, path loss, and link feasibility with exceptional accuracy.

Ratings and reviews

still more junk. you load it and nothing works unless you pay. why make it free when ultimately you just want us to pay? total scam. edit: developer have done garbage excuse not explaining why the free version is just ads and did NOTHING AT ALL. still a waste. YET ANOTHER EDIT: Sensei means Teacher, as in you should listen and learn. I installed the app years ago and all it did was show ads which failed. the app did nothing else. maybe you updated your code. but you should learn from this.

It gives good accurate results!

completely unusable without "unlocking". I understand developers needing funds to support their work, but if the app requires an unlock to perform any functions just make it a paid app. this app looks like it might have promise but is completely unusable without unlocking.
