4G LTE for in-vehicle connectivity

There is growing demand for the integration of 4G LTE technology into vehicles. The higher bandwidth and lower latency of 4G LTE deliver high performance in-vehicle wireless connectivity, meaning systems used for infotainment, navigation, and location-based services work more quickly and with less lag time. In addition, passengers can use the wireless connection for in-vehicle entertainment such as watching movies or playing games.

“Consumers and automotive manufacturers have come to appreciate the benefits of connected cars, including improved safety and maintenance,” said John Sullivan, executive director of the M2M Platform Group for Verizon Enterprise Solutions. “The AirPrime automotive module for the Verizon LTE network provides a cost-effective solution that enables automotive OEMs to take advantage of the higher bandwidth, lower latency, and network longevity LTE offers to provide better real-time navigation, location-based services, and streaming media as well as other infotainment services.”

On the leading edge of network technologies, Verizon’s 4G LTE is a logical choice for the automotive  industry, where lengthy product development cycles and the expected longevity of a vehicle mean that OEMs require networking technology that is built for the future.

Sierra Wireless is a leading provider of LTE modules for integration into devices, having first delivered 4G LTE embedded modules in early 2011, including the MC7750 LTE/EVDO module for the Verizon Wireless network. The AirPrime AR7550 is part of the third generation of Sierra Wireless modules for LTE networks.

Multicore capability aim to offer an’ entire M2M ecosystem on a module’

The AirPrime AR7 offers an advanced, cost-effective solution for telematics and other in-vehicle connectivity needs. It includes a dedicated application processor to reduce design complexity and an application framework with specific automotive libraries to speed up development time. Additionally, integrated cloud connectivity simplifies ongoing management and maintenance over the lifetime of the vehicle. By eliminating the need for separate components to be sourced and assembled, the AR7 provides OEMs with simple and scalable wireless integration at a lower cost.

Automotive-grade for reliable long-term performance

Based on years of experience in working with automotive customers, Sierra Wireless developed the AirPrime AR7 module to meet demanding automotive manufacturing standards. It is designed and tested to real-world automotive scenarios, with TS 16949 certification, automotive quality processes (PPAP, 8D, FA) and low ppm rates, tolerance for extreme operating environments, and an extended operating temperature range of -40 degrees Celsius to +85 degrees Celsius.

With over a decade of experience, award-winning expertise and more than five million automotive-grade wireless modules shipped, Sierra Wireless is a market leader in wireless technologies for the automotive market.

“The AirPrime AR7 series leverages our expertise in both building devices for LTE networks and in providing modules that meet the needs of automotive OEMs,” said Didier Dutronc, SVP, M2M Embedded Solutions for Sierra Wireless. “Combined with the power of the Verizon Wireless 4G LTE network, the AR7550 provides OEM customers with a simple, scalable way to build 4G into vehicles for both telematics and infotainment services.”

The Sierra Wireless AirPrime AR7550 module has achieved technical approval for operation on the Verizon Wireless network and samples are available to OEM customers now for testing and development purposes. Variants of the AirPrime AR7 module for LTE networks in other areas of the world are also sampling now.

Yankee Group Associate Analyst, Ryan Martin commented: “The news of Sierra Wireless’ latest M2M module and, more specifically, the connected car and its corresponding certification on Verizon’s LTE network, highlights a great option for automakers that seek a proven platform that delivers in-car connectivity over super fast LTE networks.

“At first blush, this may look like a big win for Verizon, as the news report suggests the companies have an exclusive arrangement. Upon further investigation with Sierra Wireless personnel, Yankee Group has learned that the arrangement is not exclusive — a similar module can be made available for AT&T’s network if desired. While drivers will still need to weigh the cost/benefit analysis of how their existing cellular subscriptions might change to account for in-car 4G, the AirPrime suite enables an uninterrupted connectivity experience. These units offer a high-speed data connection to LTE as well as the possibility to toggle to 2G/3G networks as needed while driving through poor coverage zones.”
