Abstract
Mobiles have become very essential part of our everyday life begin of voice call to internet access. As the development of 4G mobile wireless standards the operator need to know how to design and update their networks so that they can provide best services to the lowest possible cost. This paper presents topological planning problem of fourth generation (4G) cellular networks based on the Long Term Evolution Advanced (LTE-Advanced) standards. After describing the LTE-Advanced architecture, we focus on layout and the main problems faced in this planning. This paper provides a high level overview of antenna placement problem or the cell planning problem, involves locating and configuring infrastructure for LTE-Advanced mobile networks. The goal of this paper is to present and classify the different research works that have been done so that it can be used as a starting point for future research on topological design of LTE-Advanced networks.
