As the modem supplier for OnStar and others, Qualcomm Technologies has been a trusted advisor to the automotive industry for more than a decade—and we continue to support automakers as they deliver on new connected car experiences. Announced in March at Mobile World Congress, our latest Snapdragon modems and complementary connectivity solutions are designed to provide the foundation for advanced automotive telematics, connected infotainment, DSRC (dedicated short-range communications) and vehicle-to-everything, or V2X, communication applications.
Throughout the next decade, we can expect to start seeing more and more connected features, increased collision-avoidance safety systems and semi-autonomous capability in vehicles – leading to completely self-driving vehicles. The benefits to having autonomous and semi-autonomous vehicles—safer roads, greater fuel efficiency, city-wide traffic management, and reduced emissions—will be transformative, and advanced cloud and short-range connectivity is a vital component of that reality.
At Qualcomm Technologies we believe that providing a superior connected car platform which integrates reliable and proven LTE modems, industry-leading GNSS location functionality, as well as a dedicated applications processor will help V2X applications run smoothly and securely, and help deliver cars of the future soon. A few ways we're supporting OEMs is through our systems approach and architecture optimizations. Qualcomm Technologies’ innovation is evident in our investment on both ends of the communications link (device and network) and our active participation and involvement with the larger context of the system to which the data flows, supporting low latency and highly secure cutting-edge performance.
For Telematics and V2X, we offer an architecturally optimized platform, just like we do for smartphones and tablets—in this case, bringing both cellular and short-range communications (Wi-Fi and DSRC) into a single platform. With cellular attach rates increasing rapidly, and with V2X mandates looming, the platform is receiving significant interest. Such a solution offers not only cost optimizations and weight reduction to OEMs and enhances the security of DSRC with access to the cloud, but also a more seamless application experience. This should help OEMs add these capabilities to more vehicles and make it more ubiquitous across their models.
The Snapdragon X12 LTE modem is designed to support auto manufacturers develop next-generation systems for premium-tier vehicles while supporting greater coverage and delivering premium speeds for the savviest of drivers. The Snapdragon X5 LTE modem is designed to let automakers broadly deploy LTE in all cars. Here’s a quick rundown of the modems’ specs:
Snapdragon X12 LTE modem (9x40)
- 20nm chipset
- LTE Advanced Category 10 TDD/FDD
- Up to 60 MHz 3x CA (at up to 450 Mbps) in the downlink
- Up to 40 MHz 2x CA (at up to 100 Mbps) in the uplink
Snapdragon X5 LTE modem (9628)
- 28nm chipset
- LTE Category 4 TDD/FDD
- Up to 150 Mbps in the downlink
- Up to 50 Mbps in the uplink
Both chips support
- LTE TDD/FDD across global radio frequency bands
- The most advanced GNSS location engine supporting simultaneous tracking of multiple satellite constellations (GPS, GLONASS, Beidou, Galileo) for automotive use cases
- EU eCall (recently mandated) and ERA Glonass crash notification systems
- Integrated with a dedicated ARM Cortex A7 (1.2 GHz) processor for hosting automotive applications
- Inter-work with the Qualcomm VIVE QCA65x4 chipset to provide a comprehensive connectivity solution with Wi-Fi 802.11ac, Bluetooth 4.1 and DSRC (dedicated short-range communications)
