Define Cell, Cluster.

11. Define Cell, Cluster.

For a large geographic coverage area, a high powered transmitter therefore has to be used. But a high power radio transmitter causes harm to environment. Mobile communication thus calls for replacing the high power transmitters by low power transmitters by dividing the coverage area into small segments, called cells.
Each cell uses a certain number of the available channels and a group of adjacent cells
together use all the available channels. Such a group is called a cluster.

In the context of wireless communication, "cell" and "cluster" have specific definitions:

•     Cell (Wireless Communication): In wireless communication systems, a cell refers to a geographic area covered by a base station or cell tower. It is a fundamental concept in cellular networks, such as GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access). Each cell is served by a base station, and multiple cells together form a cellular network coverage area. Cells are typically designed to ensure efficient and reliable communication by managing the allocation of radio resources and minimizing interference.
•     Cluster (Wireless Communication): In wireless communication, a cluster refers to a group of cells that are managed together to enhance network performance and capacity. The purpose of forming clusters is to optimize resource allocation, improve coverage, and increase the overall efficiency of the network. Clustering can be done based on various factors, such as geographical proximity, traffic load, interference patterns, or specific service requirements. By coordinating the operation of cells within a cluster, the network can better manage hand offs, frequency reuse, and interference mitigation, among other aspects.

In wireless communication systems, cells and clusters work together to provide seamless coverage, capacity, and quality of service to users. Cells form the basic building blocks of the network infrastructure, while clusters allow for coordinated management and optimization of multiple cells within a designated area.
