Effect of Antenna Height and Frequency on Handoff Initiation

Abstract

In the present state of scenario, mostly all the conventional wired network systems are re-established by the wireless network systems. wireless network systems has many more applications and advantages than a conventional wired network, only problem we countenance in wireless system is at the designing stage, because The designing of a wireless system is expensive, complex as well as time consuming. So much care is required before going for the establishment of such type of systems. Mathematical analysis before the actual designing plays a vital role in cell coverage prediction, received signal strength estimation, link budget analysis and handoff of mobile radio systems. Because radio propagation is profoundly site specific and varies considerably depending on topography, frequency of operation, speed of mobile terminal, interface sources and other dynamic factor. Handoff is the key operation in cellular mobile communication systems, which is accomplished by the system but it is invisible for the user. In this paper, the received signal strength from the two base stations is calculated and plotted with respect to distance between the base station and mobile station. The different path loss models have been used and then the received signal strength is calculated with different frequency of transmission and transmitting antenna height to determine the model that can be adopted to minimize the number of handoffs. The simulation and analysis is done by using MATLAB.
