Cellular Networks

Definition

Cellular networks are communication systems that use a network of geographically distributed base stations to connect mobile devices and facilitate wireless communication. These networks operate by dividing regions into cells, each served by its own base station, allowing for efficient frequency reuse and providing coverage over large areas. They enable various applications, including voice calls, data transmission, and remote monitoring of health devices.
