How to Use This Calculator
- Enter the target coverage area in square km.
- Set the small cell range in meters for the frequency band being deployed (mmWave: 150 m, sub-6 GHz: 500 m).
- Input the target spectral efficiency in bits per Hz and the required average throughput per user in Mbps.
- Review the Number of Small Cells Required and the Site Density per square km.
- Use the Total Deployment Cost output to budget the rollout and compare against macro cell alternatives.
