The fifth generation (5G) of mobile technology is emerging as a advance communication network, delivering elevated speeds, coverage and reliability, this technology like other technologies not clear from drawbacks and limitations, 5G mobile system like other mobile systems 4G, 3G and 2G affected by interference and signal quality is going to be decreased because of higher number of C-Node-Bs which is because higher frequency and smaller coverage, in this paper, interference effect has been studied with both types cochannel and adjacent channel, best case and worst cases has been presented simulated and calculated the signal to interference ratio vs cluster size for different pathloss exponents , models and techniques of minimizing this effect has been studied starting with 5G cell planning, then a proposed network using optical fiber between C- Node-Bs, the proposed network model will minimize the interference effect to about negligible level, results shown in this paper about total length of fiber optic cables and cluster size, also, an example with best cluster size has been presented.

Since the need for larger data rates and wireless system radio networks has increased, several organizations in this industry have started to develop and implement their 5G mobile technology scenarios. Since mobile telecommunications' quick expansion has motivated companies to constantly plan and work from the first generation to the fourth generation of mobile technologies. MIMO systems and beamforming antenna arrays are expected to be very important. In the 5G wireless communication systems to be utilized after 2020, when they are paired with massive MIMO systems. In this paper, the main goal is to determine the benefits of beamforming techniques in massive MIMO systems in order to increase system throughput and reduce interference, thus eliminating and resolving the various technical challenges that are presented by the implementation of massive MIMO system architectures. The goal of this work is to contribute to the development of a 5G mobile system's C-Node-B base station transceiver. The suggested design makes use of a (64 x 64 MIMO) system and optimum the beamforming technology, MIMO parameters, and the primary fundamental parameters in beamforming.
