Abstract: This paper presents a review of the outdoor propagation prediction models for GSM 1800 MHz in which propagation model was developed after a measurement drive was undertaken for the purpose of data collection. The appearance of the foliage medium in the path of communication link has found to play a significant role on the quality of service (QoS) for wireless communication over many years. Four GSM base stations operating at 1800 MHz band were used for the purpose of measurement in sub-urban region of Patel Nagar and kargi, Dehradun. The measured values that were first fitted using fitting tool were compared with Free Space Path Loss model, COST 231 Hata model, Hata model and COST 231 Walfish-Ikegami (W-I) model. These outdoor propagation models discussed helps to measure accurate path loss prediction within a particular scenario also a good outdoor propagation model facilitates optimized network planning, design and implementation process of a wireless network.
