Long Term Evolution (LTE)

High-speed data access all over the world

Continental (Germany) has developed the Telematics module, which provides an “always on” connectivity by handling multiple cellular technologies including LTE with up to 100 Mbit/s. It features a CAN interface.

THESE DAYS, MANY FUNCTIONS AVAILABLE in the vehicle cockpit depend on fast and reliable mobile access to external data. Future connected vehicles will be a part of the Internet of Things and communicate with other cars and with the cloud. Being “always on” is therefore rapidly becoming a core requirement for modern vehicles. Continental offers with their module a solution with up to 100 Mbit/s bandwidth wherever 4G Long Term Evolution (LTE) mobile network standard is available. By integrating configurable frequency variants, interchangeable options for air interface solutions, and GPS/Glonass, and WLAN into one scalable hardware module, this LTE module can be used worldwide.

“With our new LTE-capable Telematics module, drivers around the globe can expand their capabilities with cloud services, lifestyle apps, and many more innovative features to make driving more comfortable, more efficient, and safer”, said Johann Hiebl of Continental. Applicable telematic functions include connecting a smartphone to the vehicle, on- and off-board navigation, safety and security services such as advanced automatic collision notification or remote diagnostics, premium assistance on the road, Wi-Fi hot spot for rear seat entertainment, and business productivity, plus apps. “Our new high-speed Telematics module connects drivers to what matters,” Hiebl conclueds. “We have launched Telematics with more mobile network providers than any other Tier 1 supplier. This global experience provided the basis for our new high-speed LTE Telematics module”, Hiebl said. It is scheduled to be available for vehicle mass production from early 2015.

The product architecture addresses multiple cellular technologies, including LTE, HSPA, EVDO, GSM, and CDMA. To facilitate worldwide use, the national frequency variants in the US, Europe, Russia, China, Brazil, and many other countries are supported. The module also offers speech and hands-free technologies. Consumer device connectivity options include Wi-Fi, Bluetooth, and USB. To interface with the vehicle, automotive network systems such as CAN, Most, LIN, Ethernet, USB, and Wi-Fi are supported. Despite its functionality the overall solution is integrated on a small printed circuit board. This PCB holds the full chipset – including the integrated circuit – plus RAM/Flash and still measures no more than 35 mm x 40 mm. Frequency variations, Wi-Fi, and RAM/FLASH can be adapted to the application, and cellular chips with identical footprint are available in multiple variants.

One of the system’s biggest advantages is its bandwidth: compared to previous 3G technologies, 4G LTE brings the bandwidth for many features in the vehicle. Bandwidth is a prerequisite for real-time experience when using HTML 5 apps and dynamic content, on-line location-based services, low-latency Vehicle-to-X (V2X) and Vehicle-to-Infrastructure-to-Vehicle (V2I2V) communications, fast media streaming and map updates, plus personalized cloud services and mobile office connectivity.
