The vital objective of this article is to analysis about Distributed Antenna System. Distributed antenna system offers perfect solution for wider wireless coverage through the splitting of antennas from the necessary geographical area. Usually smaller antennas connected with CAT5, Fiber or Cajole cables; replace a sole antenna with higher energy consumption. The installation of any distributed antenna system has more to offer over the conventional method. The entire process of installation must be carried out with the systematic approach. Understanding having a of components involved is important to identify the required network architecture.
