This document discusses ways that LTE can help boost average revenue per user (ARPU) for mobile network operators. It suggests that LTE enables faster speeds and more reliable mobile broadband, allowing for new applications that can drive additional revenue. These include real-time apps, location-based services, mobile health apps, high definition content, and quality of service features that users may pay premiums for. Network sharing and fixed-mobile convergence are also discussed as ways to reduce costs and increase customer loyalty. However, the document notes that simply focusing on ARPU may not be the best approach, and that factors like passive data devices could impact ARPU metrics.
