A novel on smart antennas to improve performance in wireless communications

Abstract

In wireless communication, the broadcast server serves numerous clients. The exchange of information from server and access by the clients takes place in a cyclic path using the directional antennas. But directional antennas have several drawbacks. So the multiple directional antennas were used to replace the fixed directional antenna systems. When using the multiple antennas to get the desired improved performance, we need to consider the geographical distribution of all the clients present in the coverage area of system. All these disadvantages motivate us to develop a technique named as a wireless push system developed using adaptive smart antenna with rescheduling application to be used at broadcasting server. Smart antennas can vary the beam widths according to client position using suitable algorithms. Beam width of the antenna is changed as per the changing position of the client and appropriate changes are introduced in the broadcasting schedules. This approach will bring the desired improvement in system performance.
