This wireless estimator tool helps you accurately determine the wireless signal coverage for your specific area.
Wireless Estimator
This tool helps you estimate the coverage quality of a wireless link based on several key parameters. Ensure all input fields are accurately filled to get the best results.
How to Use
- Enter the frequency in MHz.
- Enter the distance between the transmitter and receiver in kilometers.
- Enter the transmit power in dBm.
- Enter the antenna gain for both the transmitter and receiver in dBi.
- Enter the cable loss in dB.
- Enter the receiver sensitivity in dBm.
- Click “Calculate” to see the result.
How it Calculates
The estimator uses the following formula to calculate coverage quality:
- Path Loss (dB) = 20 * log(distance in meters) + 20 * log(frequency in MHz) + 32.44
- Link Budget (dB) = Transmit Power + Antenna Gain (Tx) – Cable Loss + Antenna Gain (Rx) – Path Loss
If the link budget is greater than or equal to the receiver sensitivity, the coverage is considered “Good”. Otherwise, it is considered “Poor”.
Limitations
This estimator is based on free-space path loss and does not account for obstacles, terrain, or other environmental factors which might affect real-world performance.
Use Cases for This Calculator
