Cellular Network Design Diagram As shown in figure 3, the mobile cellular network consists of two main subsystems: the radio access network (ran) and the mobile core. the ran manages the radio resources (i.e., spectrum), making sure it is used efficiently and meets the quality of service (qos) requirements of every user. In this portfolio, we are going to look at cellular networks from a systems engineering perspective and propose an improved design over the existing network. we start from the basics to look at design requirements and then apply various techniques including house of quality and functional analysis.
Cellular Network Design Diagram Because of this, today's core network architecture resembles what we show in figure 1: the union of multiple core networks from different technologies (i.e., 2g, 3g and lte). the overall. Explore the evolution of mobile network architectures from 2g 3g to lte epc, 5g, ims, gprs, and nb iot. switch tabs to view interactive, modern diagrams for each generation, with key network elements and interfaces highlighted. Figure 3.1 illustrates the concept of cellular frequency reuse, where cells labeled with the same letter use the same group of channels. the frequency reuse plan is overlaid upon a map to indicate where different frequency channels are used. In a cellular system, the whole geographical service area is divided into a number of clusters having finite number of cells. the k number of cells in a cluster (cluster size) use the complete set of available frequency channels, n. each cell in the cluster contains j = (n k) number of channels only therefore, n = j x k; where j ≤ n 20.

Mobile network has become an integral infrastructure for our connected world, look how 5g will revolutionize our society. Cellular networks • to date, the only operaonal large ‐scale wireless network with wide ‐area coverage and mobility support. The value for n is a function of how much interference a mobile or base station can tolerate while maintaining a sufficient quality of communications. from a design viewpoint, the smallest possible value of n is desirable in order to maximize “c”. Frequency reuse (frequency planning): is the design process of selecting and allocating channel groups for all of the cellular base stations within a system.
