Automobiles are becoming software-defined, wirelessly guided, self-driving, data consuming devices. Car makers are realizing these data-hungry transport pods will need more economical and robust mobile connections that won’t drop out and create road havoc.
“From the OEM side, automakers are relying on a number of types of connectivity they’re trying to weave all together,” said connected-car consultant Dan Teeter. “Some are a primary service for a feature, and some are a back-up service. NextGen Broadcast or ATSC 3.0 could act as either or both.”
There are three connected-car features where ATSC 3.0 high-speed data delivery is emerging as the most effective and efficient option: Infotainment, software updates and geolocation. Teeter, along with Sony’s Luke Fay; and Mark Aitken and Tony Rangel of Sinclair, outlined use cases for each in the second of a three-webinar series on ATSC 3.0 and connected cars, with cyber-auto research executive Alex Oyler presenting market-penetration data.
Globally, nearly three-quarters of the passenger cars sold in 2022 will have internet-type connectivity, “trending to 100% by the end of the decade,” according to Oyler, North America director for SBD Automotive.
Decongesting Data Delivery
By 2030, nearly 1 million fully autonomous vehicles are expected to be on the road in the form of robotaxis, delivery trucks and public transportation. This digital automotive transition will need a “diverse set of enabling technologies,” Oyler said.
It’s increasingly evident that ATSC 3.0 is an ideal enabling technology. It can send one file to a million moving vehicles simultaneously versus sending the same file a million times to each vehicle.
“This is another wireless pipeline, purposefully designed for mobile. Its IP-based architecture allows inter-networking with cellular networks,” said Aitken, one of the ATSC 3.0 pioneers. “It provides the ability to reach one-to-many across multiple platforms.”
