A cellular network is a wireless communication technology that derives its name from the cellular network structure. In a cellular network, the communication coverage area is divided into multiple cells, each controlled by a base station that communicates with mobile devices via wireless signals. The development of cellular networks has gone through several stages,cellular module from 1g to 5G, each generation of technology has been continuously improved and upgraded, making cellular networks one of the core technologies in modern communications.
So, why is cellular network called cellular network?
1. Origin of Cellular Networks
To understand why cellular networks are called cellular networks, we must first understand the origin of cellular networks. The concept of cellular networks first appeared in the 1940s,lte module when D. H. HMS Roberts, an engineer at Bell Labs in the United States, proposed the concept of a “cellular communication system”, which he said should be like a honeycomb, consisting of a number of cells, each of which is controlled by a base station. This concept laid the foundation of cellular networks and laid a solid foundation for the development of cellular network technology in the future.
2. Structure of Cellular Network
A cellular network is called a cellular network because its network structure is very similar to that of a honeycomb. In a cellular network, the communication coverage area is divided into many cells, and each cell is controlled by a base station, which communicates with mobile devices through wireless signals. These cells form a structure similar to a honeycomb, hence the name cellular network.
Cells in cellular networks are usually hexagonal in shape, this is us because the hexagonal shape is the most fully exploited shape for development space and can reduce overlaps and gaps by maximizing different degrees. The size and shape of each cell is needed to be determined based on topography, buildings and other factors to ensure the integrity and continuity of the enterprise’s entire communication technology coverage area.
3. The working principle of cellular network
The working principle of cellular network is based on wireless communication technology. In a cellular network, each cell is controlled by a base station, which communicates with mobile devices through wireless signals. Mobile devices can be cell phones, tablets, laptops, etc. They need wireless communication capabilities to communicate with the base station.
When a mobile device enters a cell, it automatically connects to the cell’s base station, which sends the necessary information to the mobile device, such as the cell number, frequency, and so on. The mobile device communicates with the base station signal according to the information to realize the transmission of voice, data and other information.
When the mobile device moves from one cell to another, it also automatically switches to the base station in the new cell. This process is called “handover”. Switching is an important feature of cellular networks, which ensures that mobile devices remain connected throughout the entire communication coverage area, enabling seamless communication.
4. Characteristics of Cellular Networks
The unique structure and working principle of cellular network endow it with many enterprise characteristics, which have made cellular network has become one of the core technical issues in the field of modern information and communication.
Wider coverage, cellular network cell coverage is wider, can cover cities, villages, oceans and other terrains and environments, to achieve global communications.
High reliability, cellular network cells are independent of each other, when a failure occurs, only one cell is affected, the whole network is not affected, ensuring the reliability of communication.
High efficiency, the cell size and shape of the cellular network are determined according to the terrain, buildings and other factors, which can minimize the overlap and gaps and improve the utilization and efficiency of the network.
Mobility, mobile devices of cellular networks can move freely throughout the communication coverage area, realizing seamless communication and convenience.
Overall, the cellular network culture is called cellular network because its network economic structure is very similar to that of a honeycomb. The origin of the cellular network we can trace back to the 1940s, after years of development and improvement of their own, has gradually become one of the core enterprise technology issues in the field of modern information and communication engineering. The basic principle and characteristics of cellular networks are very unique, making it play a very important role in a wide range of applications and management fields. With the gradual popularization of 5G technology, the application market prospect of cellular network will be more broad.
