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.
