Mobile technology has made communication easier and faster. People communicate in a matter of picoseconds, with little or no inhibition, regardless of their distance or location. Mobile networks are rapidly expanding all over the world. The demand led to the evolution of different technologies to meet with traffic challenges. Challenges are still evident as the cellular network system faces dynamic and chaotic behavior that needs to be resolved intelligently without human intervention. The current paper presents the state of the art of artificial intelligence (AI) in enhancing the performance of cellular networks. This paper summarizes the AI concept and reviews its applications in cellular network design, operations, and optimization. A special focus is laid on the advantages and disadvantages of AI application and a holistic study of the challenges is undertaken in order to give new research directions.

This project is concerned with the design, analysis and construction of a solar conversion system which consist of a solar panel an inverter and a battery. The solar panel traps the sunlight and converts it into direct current which is used to charge the battery through the charging circuit. The inverter converts the direct current power into alternating current power. The battery is being charged from either solar panel or power mains. The components that make up the system and their arrangement into sections or circuits are discussed. A test was done to ascertain its effectiveness. A solar conversion system is recommended to be used in homes, offices and industries. It is very expensive but it is hoped that the cost will reduce owing to the on-going research in the field.

Dispersion decreases the bandwidth carrying-capacity of the reliable transmission medium of fibre optics with all its advantages over other orthodox media of copper, coaxial etc .It is inherent in the wave length method integrated into the system, to enable long haulage of modulated signal for propagation. It is a cost effective means of increasing the capacity of long haulage optical transmission system, however it limits the rate at which the intelligent signal can be received through the channel at the required bit error rate (BER). Pressure is a catalyst that facilitates the broadening of signals at the receiver. The utilisation of Guassian Minimum Shift Keying (GMSK) simulation factors are the gear system employed in resolving the problems of dispersion, attenuation bending losses etc Poor installation of optic fibre network system equally gives room for external pressure and temperature effect on the fibre.

The Optics Fiber link is implemented to satisfy various types of networks, with a wide range of transmission capabilities and improved speed in signal delivery. The link carries multiple signals and for adequate transmission, multiplexing of signals, each signal component, is aggregated and transmitted over a common link which is regarded as multiplexing. The wavelength-routed network bridges the gap of the timeshare, which has retardation on speed and efficiency. The wavelength division multiplex (WDM) is a multiplexing technique designed to suit fiber optics and achieves speed demands, as against time-division multiplexing(TDM) for analog continuous signals (CT) and frequency division multiplexing(FDM) for discrete-time signals (DT). The synchronous optical network (SONNET) and synchronous digital hierarchy (SDH) and the Asynchronous transfer mode (ATM) create an inter-switching system using various matrix dimensions, of 2 X 2, 8 X 8 and other multiples to achieve a versatile routing switching technique. Wavelength division Multiplex and it's a dense modification (DWDM); have greatly improved the quality and speed of signal transmission over all other techniques.
