Estimate network bandwidth coverage radius from explicit engineering assumptions. The tool shows the primary planning value plus supporting figures so you can see how traffic, margin, geometry, or path components affect the result. Use measured inputs when available and treat the output as a design estimate rather than a service guarantee.
The result is the theoretical free-space radius at the receiver threshold. For deployment, use it as an upper-bound screening estimate and confirm coverage with a site survey.
Planning estimate only. Validate assumptions against equipment specifications, measurements, and local operating conditions.
At 20 dBm, 5 dBi combined gain, 8 dB other losses, −60 dBm sensitivity, and 2,400 MHz, allowable path loss is 77.0 dB and free-space radius is 70.4 m.
No. It is a free-space link-budget estimate. Indoor prediction requires wall losses, floor losses, multipath, interference, and a site layout.
For the same link budget, free-space path loss increases with frequency, so the modeled distance decreases.
Use the threshold for the data rate and reliability you need, not the most sensitive rate printed on a device specification.
Use gain values and regulatory limits consistently. Effective radiated power may be restricted, and cable loss should be subtracted.
Obstructions, interference, device orientation, noise, multipath fading, and required throughput all reduce usable range.
