Mobile phone signals propagate between different areas through base stations in the form of electromagnetic waves, but due to the limited distance of electromagnetic wave transmission and its gradual attenuation with increasing distance, multiple base stations need to be established to cover a larger area. The coverage area of base stations is distributed in a hexagonal shape, with one base station at the center of each hexagon, making the entire network like a cell, ensuring that at any point, mobile phones can establish signal contact with the nearest base station, meeting the needs of mobile communication users for signal continuity and stability. ‌.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Cellular mobile communication network refers to a "mobile communication network" that divides a service area into several cellular adjacent cells and uses frequency space multiplexing technology. It consists of three parts: mobile telephone exchange, base station, and mobile station. The mobile telephone exchange is connected to the local telephone network to facilitate communication between fixed users and mobile users, as well as between mobile users themselves. In this network, a mobile switching office serves a geographic area, forming a service area consisting of several cellular adjacent wireless cells. Each cell is equipped with a base station responsible for communication with mobile users within the cell. The main equipment in the mobile telephone exchange is the digital program-controlled mobile telephone exchange, which is responsible for the connection, control, and management of mobile communication within the service area. Mobile telephone exchanges are connected through inter office signaling, enabling roaming communication. The key technologies of cellular networks include wireless transmission technology, frequency reuse technology, etc. Through frequency reuse technology, different base stations can use the same frequency for communication.
