Connected Car

Connectivity is hitting the road.

As drivers and passengers become more digitally savvy and their needs for on-the-go connectivity become more sophisticated, the automotive industry is experiencing growing demand for in-vehicle network connectivity and bandwidth. In fact, analysts predict that by 2025, every new car will include some form of connectivity.

At the heart of the connected car are the semiconductor chips that make connectivity possible. Broadcom is leveraging its expertise in wired and wireless communications to deliver innovative technology to the automotive industry, enabling automakers to satisfy rising consumer demand for seamless connectivity on the road.

Automotive Applications

Broadcom's connectivity technologies enable low-cost deployment of a variety of advanced driver assistance systems, from rear view cameras and surround view park assist to object detection, night vision, adaptive cruise control, and lane departure warnings.
From center stack module connections and digital amplifiers, to navigation systems and rear-seat entertainment systems, Broadcom's automotive-grade solutions provide drivers and passengers with the advanced features needed for a truly connected experience on-the-go.
Through the integration of Wi-Fi, Bluetooth, GPS, Near Field Communication and Ethernet technologies, Broadcom automotive chips enable a host of telematics applications, including mobile hot spots, navigation, keyless entry and hands-free communication.
The low-power features of Broadcom technologies enable automotive use cases beyond infotainment and advanced driver assistance systems. Broadcom provides seamless connectivity with the antenna module, enabling the delivery of AM/FM radio, satellite radio, satellite TV and LTE services.

Industry Adoption

Broadcom's BroadR-Reach automotive Ethernet technology is already on the road today, enabling a number of advanced features in a broad spectrum of vehicles.

Broadcom is a founding member of the OPEN Alliance Special Interest Group (SIG), an industry consortium focused on driving wide scale adoption of BroadR-Reach® automotive Ethernet as the standard in automotive connectivity. Membership in the automotive OPEN Alliance SIG has grown 40x since its inception in 2012, with representation from nearly 250 of the world's leading automakers and technology companies.

Serving as the car's network backbone, Broadcom’s BroadR-Reach automotive Ethernet technology enables the deployment of advanced safety and infotainment features beyond the luxury class, meeting growing consumer demand for a truly connected experience on-the go.

Automotive-Grade Near Field Communication

Near Field Communication (NFC) technology, which is has become commonly associated with mobile payments, has found solid traction within the automotive industry. Broadcom's highly-integrated automotive-grade NFC chip with tap-to-connect technology simplifies the set-up process for mobile device connectivity within the vehicle and enables comfort and convenience applications such as keyless entry and vehicle settings.

Drivers can pair a mobile device simply by tapping it against the dashboard, rather than navigating menus on two separate screens. NFC-enabled digital key use can also be extended beyond the vehicle for tasks such as mobile payments and access to restricted buildings or parking garages.

Integration of NFC in a windshield allows an NFC-enabled digital key to exchange data such as authentication, user profile and vehicle information—an application that will be especially useful in simplifying the car rental process.

Broadcom's ultra-low-power, small form factor NFC chip reduces power consumption by 60 percent, uses 30 percent fewer components and a 35 percent smaller board area than previous generation devices. The automotive-grade device is optimized to meet the stringent requirements of the automotive industry such as extreme temperature tolerance, as well as AECQ100, ISO9001 and TS16949 manufacturing guidelines.

Automotive-Grade Wi-Fi/Bluetooth

Broadcom's wireless automotive chips allow drivers and passengers to easily sync and stream content from mobile devices to the car's infotainment system and rear-seat displays, while enabling high-speed connectivity beyond the vehicle.

Automakers can leverage in-car Wi-Fi to deliver software upgrades and new features. Drivers can use a mobile device to check remotely on their car's location, gas levels and mileage—and that same device can receive alerts about vehicle performance and diagnostics. In-vehicle Wi-Fi technology also enables mobile hot-spots for on-the-go connectivity without relying on cellular service. Wi-Fi is also expected to play a key role in Vehicle-to-Everything (V2X) communications and the enablement of the self-driving vehicle, particularly as standards continue to evolve to support Gigabit speeds and beyond.

Based on the latest generation IEEE 802.11ac standard, Broadcom's combo solutions with integrated 5G WiFi technology provide the bandwidth required for multiple in-car displays and resolution of up to 1080p, allowing uncongested 5 GHz video to coexist concurrently with 2.4 GHz.

Going beyond simple hands-free communication, Broadcom's integrated Bluetooth Smart Ready technology allows products to sip power at an incremental rate, enabling connectivity between the car and the latest wearable tech gadgets.

One of the most immediate applications enabled by Wi-Fi and Bluetooth Smart is the smart remote, allowing drivers to use their smartphone to remotely adjust seat, temperature and infotainment settings while providing vital data on automotive performance and diagnostics.

BroadR-Reach® Automotive Ethernet

As consumer demand for in-vehicle connectivity continues to ramp at a rapid pace, automotive manufacturers and tier one suppliers are under pressure to deliver competitive, innovative features while minimizing cost. Broadcom’s BroadR-Reach® automotive Ethernet solutions allow multiple in-vehicle systems (such as infotainment and automated driver assistance) to simultaneously access high bandwidth data over a single, unshielded twisted pair cable.

Broadcom's BroadR-Reach automotive portfolio delivers high-performance bandwidth of 100 Mbps and beyond while dramatically reducing connectivity costs up to 80 percent and cabling weight as much as 30 percent. By eliminating cumbersome, shielded cabling, automotive manufacturers can significantly reduce connectivity costs and cabling weight.

Optimized to meet the stringent requirements of the automotive market, Broadcom’s automotive products meet in-car EMC requirements and extreme automotive temperature grades. Broadcom is also one of the few semiconductor suppliers to be TS16949 compliant and AEC-Q100 qualified.

The Broadcom automotive Ethernet product portfolio consists of six devices including three highly integrated switches with embedded PHYs, and three stand-alone PHY solutions. All devices are immediately available.

1 Based on current market prices for unshielded single twisted pair FlexRay cables

2 Based on combined weight of 2-meter twisted, single-pair FlexRay cables and connectors
