Decision Process : Estimate Interference : Reduce Cell Area

Step 11 : Reduce Cell Area If you are here, the calculations you made earlier are wrong. Decreasing cell area may require you to review your frequency plan and the cell radius you set. Use the data you've collected up to this point to find the cell radius, including: Potential cell areas Anticipated load per square mile (Erlangs) Additionally, you want to consider the antenna type(s) you are using in your system design. Typically, new cellular systems are implemented with omnidirectional and some sectored base stations having large growth potential in radio channels. Steps to reduce a cell's radius: Use the Traffic Tables to determine the load (in Erlangs) each cell can handle based on the number of channels/users initially planned. Based on the traffic intensity and estimated subscriber densities, estimate the radius of cells that serve the parts of the system with the highest traffic loads. Divide the coverage area into cells with a standard reuse grid pattern overlay. Locate preliminary cells of the radius determined above in the high traffic areas using the topographic maps. After you reduce the cell area, you need to go back to the flowchart and re-calculate subscriber numbers, anticipated load per cell, etc.. Click here to finish the Decision Flowchart.
