Shaping the Future with Multi-Mode Chipsets for LTE: What Challenges Lie Ahead?
What Challenges Lie Ahead? • Deployment models for early launches – the role of legacy networks and impact on devices • New and refarmed spectrum opportunities – the proliferation of RF bands • Back to the basics: voice – how to enable voice and legacy services over LTE?
Hotspot LTE deployments will come first • LTE boosts data capacity in dense urban areas • 3G provides ubiquitous data coverage and voice services • Seamless service continuity with 3G using multimode devices LTE HSPA Coverage
What does all this mean for LTE devices? • Multi-mode capability a must • Evolved HSPA capability for seamless user experience outside LTE coverage area • Mobility supported between LTE and 3G/2G networks • High level of integration and reuse across technologies for cost-effective, power-efficient, compact devices Qualcomm uniquely positioned to support first multimode LTE devices
What does all this mean for LTE devices? • A multi-mode LTE/HSPA+ device needs to support high number of RF bands • The number of possible RF band combinations also increases • Potential impact on device complexity and cost, risk of device fragmentation • High level of RF IC integration is a must – a single SKU for multiple markets Qualcomm RF IC solutions uniquely positioned to support multimode & multi-band LTE devices
Voice and SMS ... different approaches • CS fallback • voice calls are circuit switched & handled by “fallback” technology • VoIP over IMS over LTE • Common platform (IMS) to deliver voice & operator controlled applications • Voice over LTE with Generic Access • Basic tenet of Volga – deliver “native” circuit switched voice directly over LTE • SMS • over CS domain using SGs interface, or over IMS over LTE
What does all this mean for LTE handsets? • Various options for voice support in multi-mode LTE devices may lead to fragmentation • A standard-based solution is therefore needed. • SMS over CS first, then over IMS over LTE • CSFB first, then VoIP over IMS over LTE • … and lastly all the above packaged in a device with openOS and superior Multi-Media performance for successful launch of LTE handsets in the market Qualcomm uniquely positioned with the MSM8960 to enable first LTE handsets of superior performance
