4. Electronic House Expo/Fall 2001 Long Beach S73: Integrating DSL and Wireless in the Home DSL Application Bundles Carrier benefits –improved operational efficiencies (digital capacity vs. analog), –improved customer loyalty, –revenue protection (e.g. long distance), –new revenue sources (more phone lines), and –competitive barriers (limit switching incentives). Individual services become commodities. Carriers bundle or perish. Consumer benefits –lower monthly costs, –new sources of value, –new functions for existing devices, and –the simplicity of a single bill and support #. will happen even without consumers demanding it.

22. Electronic House Expo/Fall 2001 Long Beach S73: Integrating DSL and Wireless in the Home What Wireless Technology Can Deliver These Applications? HomeRF is ideal for broadband homes. Other home net technologies fall short. Addressing only near term apps may not yield a proper base for service providers to build upon. Interference may become a key issue for service providers in dealing with wireless networking.
