Fresnel Zone Calculator

Quick assessments of signal quality and obstructions in the Fresnel zone

The Fresnel Zone Calculator mobile app offers the following key features:

1. **User Input Flexibility**:
- Allows users to input critical parameters such as distance between transmitter and receiver, frequency of the signal, Fresnel zone number, and heights of the transmitter and receiver.
- Supports input for potential obstructions, including their height and distance from the transmitter.

2. **Accurate Fresnel Zone Calculation**:
- Computes the effective distance between transmitter and receiver, considering their height difference.
- Calculates the radius of the specified Fresnel zone and determines if an obstruction impacts the signal.

3. **Obstruction Analysis**:
- Evaluates the effect of obstructions by calculating the Fresnel zone radius at the obstruction point and determining signal clearance or penetration.

4. **Link Budget and Signal Quality Assessment**:
- Calculates the free space path loss and overall link budget based on the transmission power and receiver sensitivity.
- Assesses signal quality, indicating whether the signal is "Good" or "Poor" based on the link budget and obstruction clearance.

5. **User-Friendly Interface**:
- Simple and intuitive interface for inputting data and receiving clear, concise results.
- Real-time calculation and display of results, ensuring users can quickly evaluate the wireless link.

This app is a powerful tool for anyone working with wireless communication, enabling quick and precise assessments of signal quality and potential obstructions in the Fresnel zone.
