Why are cellular network less expensive to build than phone systems that rely on landlines?

Cellular networks are less expensive to build than phone systems that rely on landlines primarily due to the infrastructure requirements. Landline systems require a physical network of cables and wires to be laid out, often underground or on utility poles, which can be costly and time-consuming. In contrast, cellular networks rely on wireless technology and can be deployed more quickly and at a lower cost, as they require fewer physical components and can be expanded more easily. Additionally, cellular networks can cover larger geographic areas with fewer base stations compared to landline systems, reducing overall infrastructure costs.
