How do cellular networks organize coverage?

Cellular networks organize coverage by separating land into distinct geographic areas known as "cells." Each cell is served by a physical base station, which communicates wirelessly with mobile devices within that cell. This architecture allows for more efficient use of the available radio spectrum and enables multiple users to share the same frequency bands without significant interference.

By dividing coverage into cells, cellular networks can manage resources better and extend coverage over larger areas, while maximizing the capacity and quality of service. This segmentation facilitates handoffs of calls and data sessions as users move from one cell to another, ensuring continuous service without noticeable interruption.

The other options do not accurately describe how cellular coverage is organized. A single larger coverage area would not effectively utilize the available spectrum in densely populated areas. Utilization of fiber optics is generally related to backhaul connections between cells to infrastructure rather than the organization of coverage in the cellular network itself. Similarly, physical routers are not the primary mechanism for cellular coverage; they are more pertinent to local area networks rather than the cellular structure of land organization.
