1. Shaping the Future with Multi-Mode Chipsets for LTE: What Challenges Lie Ahead?

2. 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?

3. Hotspot LTE deployments will come first
EV-DO Rev. C Technology Overview
July 6, 2018
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
QUALCOMM Proprietary 3

4. 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

5. Spectrum: opportunities … and challenges5

6. 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

7. 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

8. 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
