Validation of Modified Approach to Estimate the Propagation Path Loss in Urban Area to Sustain the QoS during Dust Storms

Dinesh Sharma, R.K. Singh

Abstract


Over the past 15 years there have been rapid advances in wireless technologies and an importance of radio frequency communication system is expanding day by day due to its advantages. In the mean time, a huge no. of researchers are investigating varies aspects of such field. GSM is one of the most widely used technologies in the world of mobile communication. In this paper, we would discuss the influence of propagation environment in a GSM mobile network. Here we discussed the path loss during summer (when dust storms take place) in jaipur (State: Rajasthan; Country: India) by computing the received signal strength at various distances for four different visibility conditions. The Hata and many other path loss propagation models are compared with the measured data taken in the drive test using TEMS. The result shows that the measured data and the Hata model are close while the other models undervalue the path loss phenomena. The significance here is that various forms of precipitation such as storms of sand and buildings in the urban region of Rajasthan lead attenuation in the received signal strength. The modification of hata model is given by considering building effects and dust storm effects in the above mentioned area. In last section the modified path loss model is compared with Previous work on the similar area which given by D.D.Dajab and Naldongar Parfait to highlight the proposed work.
