The concept of a cell in cellular networks is used to enable efficient frequency reuse and to cover large geographic areas with continuous communication service. By dividing the network into smaller, manageable cells, each with its own base station, multiple benefits are achieved.
Followings are some of the main advantages we can think of:
- Spectrum Efficiency: Allows for the reuse of frequencies across the network in a pattern that minimizes interference, maximizing the use of limited available spectrum.
- High Capacity: Supports a large number of users by allocating and reallocating bandwidth where it's needed most, based on user distribution and traffic demand.
- Reduced Power Consumption: Enables mobile devices to operate at lower power levels because of the shorter distances to the base station, which prolongs battery life.
- Improved Quality: By reducing the distance between the user's device and the base station, signal strength is higher and call quality is improved.
- Scalability: Networks can easily expand by adding more cells in high-demand areas without overhauling the existing infrastructure.
