Frequently Asked Questions

Find Quick Answers

What is path loss in RF communication?

Path loss is the reduction in power density of an electromagnetic wave as it propagates through space. It's calculated using the Friis transmission equation and depends on frequency, distance, and antenna characteristics.

How is EIRP calculated?

EIRP (Effective Isotropic Radiated Power) is calculated as transmitter power plus antenna gain minus cable/connector losses. It represents the power that would be radiated by an isotropic antenna to produce the same power density.

What is the Fresnel zone and why is it important?

The Fresnel zone is an elliptical area around the line-of-sight path between two antennas. Keeping this zone clear of obstacles is crucial for optimal signal strength, as obstructions can cause signal degradation through diffraction and reflection.

Can I use this tool for 5G network planning?

Yes, the RF Analyzer supports frequencies used in 5G networks (including sub-6 GHz and mmWave bands). Simply input your specific frequency parameters to analyze path loss and other critical metrics for 5G deployment.
