uses. These parameters depend upon the type of management system that is being used in the network and its capability to handle the amount and types of network elements. One typical example of parameter settings is shown in Figure 3.24. There may be more parameters than shown depending on what type of master is being used and how the management channels are being transferred and controlled.

Trans- mission planning itself was considered to be a line-of-sight job, and any problems in the network coverage capacity or quality were attributed to the radio part of the network. With more and more studies being conducted on mobile networks, it was found that transmission and the core network play an equally important role in contributing to a highly efficient network. Moreover, some networks that came during the evolutionary years of GSM were designed in a hurry, without much consideration for future capacity requirements and the knowledge that the quality of transmission network would affect the quality of the whole network. TRANSMISSION NETWORK PLANNING AND OPTIMISATION In Chapter 2 we saw that radio network optimisation is a process that starts almost simultaneously with the radio planning process. This is not the case with transmission network optimisation. The main reason for this is the static nature of the transmission network. The transmission network, once it is up and running, should not be touched until and unle
