0004614-1 Figure 1 Cell-Repeat Patterra 4-Cell 7-Cell 12-Cell 21-Cell Source; Dataquest July 1989 The number of cells in each cluster has a significant impact on the overall capacity of the system. The smaller the number of cells per cluster, the larger the number of channels per cell, and consequently the traffic carried per cell is higher. However, there is a trade-off. Since more channels are being used per cell and the cluster size is smaller (fewer cells), then the distance between cells using the same channels reduces, with the consequence that interference from adjacent clusters increases (co-channel interference). The total number of channels per cell (and therefore, the traffic) is governed by the total number of channels available and the cell-repeat pattern that is: Total number of channels per cell Total number available channels Cell-repeat pattern (4, 7, 12, 21) However, traffic in a particular area can be increased (bearing in mind interference constraints) by reducing the cell size, thereby increasing the number of available radio channels in that area. © 1989 Dataquest Incorporated July ESAM Newsletter
System Structure Each cell's base station is connected to a switching center, which is a modified central office switch. In practice, a cellular network will consist of several interconnected switching centers, which are themselves also connected to the public telephone network (see Figure 2), This configuration enables the full permutation of call types to be initiated and completed, that is, PSTN to mobile, mobile to mobile, etc. Two main features within a cellular system enable efficient communication with a mobile subscriber to be maintained. The first of these is the process of "registration", which is the ability of the system to maintain a knowledge of an individual mobile's whereabouts. This is described below. 0004614-2 Base station Figure 2 Cellular Radio Network To PSTN To Other Mobile Switching Centers Source: Dataquest July 1989 ESAM Newsletter © 1989 Dataquest Incorporated July
