This document presents a study on the market potential of Reliance Jio 4G services in Mumbai. The objectives are to identify ideal locations for network towers and areas for small cells, and to understand customer preferences for 4G services. The study uses a stratified random sample of 30 respondents in Badlapur East. Key findings indicate retailers are reluctant to sell Reliance services due to lower margins, and customers prefer other networks due to connectivity issues with Reliance. The conclusion is that improving existing 2G and 3G services is crucial for building a customer base for the new 4G network.
