DESIGNING THE GLOBAL SYSTEM FOR MOBILE COMMUNICATIONS "GSM-900" CELLULAR NETWORK UP TO THE NOMINAL CELL PLAN IN TRIPOLI, LIBYA

The construction and design of cellular networks are complex processes. They involve the selection of the necessary components and the allocation of support infrastructure. In this study, we introduce an integer programming model that can help network designers maximize their net revenue. The model takes into consideration various factors such as the cost of running a business, the bandwidth available, and the customer area's revenue potential. It also takes into account the sizes and locations of each cell. This research provides a variety of solutions for designing and building cellular networks. This study takes into account the various factors that affect the design and construction of cellular networks. It also takes into account the channel sizes and locations of each cell. It is specific research and given the spectrum (20 MHz), channel bandwidth (200 kHz), and C/I = The minimum operating C/I of 15 dB, a spectrum 20MHz and fullduplex channel bandwidth is 200KHz. The various components of a network's start-up point, such as the network type, multiple access protocols, and control principles, are based on the frequency band for reuse and the table-building process. The cell planning process is based on the code division and frequency division of the GSM frequencies. In code division cases, the users and base stations of the same network are separated by codes.
