Fringe ideas about 5G might not be implemented, but the core ideas probably will be. This does not provide us with a complete specification of 5G yet, but it gives us the ability to Different researcher have used different antenna design based on adaptive technologies such as Multiple Input, Multiple Output (MIMO), Complementary Metal Oxide Semiconductor foresee its core features. Antenna design depends upon the operating frequency and required bandwidth. The candidate for 5G spectrum are 28GHz, 38GHz and 60GHz many more.

PSO is getting some serious attention in recent era in optimization problem. It reduces the computational efforts and memory load. It is the artificial intelligence which is inspired by the social movement of elements in a group, for example birds flock or fish school etc. Optimization techniques are stochastic, deterministic, random and probabilistic. Stochastic technique is used where the information about the search space is not exactly known. Inertia weight is a major parameter which ominously effects the union, manipulation and exploration trade of in PSO technique. This article deals with the effect of the inertia and acceleration coefficients on the selection of a satellite that obeys the PSO algorithm.
