Path loss modeling for Indian cities — Some observations

This paper interprets drive test based signal measurements in both urban and semi-urban Indian scenario using high-end smart phones with open source applications and high-end spectrum analyzers integrated with planning and optimization tool provided by Tata Tele Services, a major Indian telecom operator. From the drive test results, we observe that the existing path loss models such as Hata, Okumura, COST-231-Hata and COST-231-Walfisch-Ikegami models are not accurate for Indian terrain conditions and a fresh study is required in this direction.
