"The number of sensors on each race car has tripled, with around 750 of them, each sending back a different data stream, amounting to around 1.5 terabytes per car per race. Telemetry used to be pretty basic-a TV feed, throttle, brake, and steering applications, and so on. Now a small squad of engineers sits at banks of screens in the back of the garage, hidden away from the cameras, in constant link with their colleagues in the Milton Keynes factory."
""We need as well to bring it straight away to Milton Keynes because it's helping us to fine-tune the setup-so when you are here on Friday-and it's helping us as well on Sunday to make the best decision for the race strategy. So that's why it's very good to have a lot of data, but you need as well to transfer it back and forth," Maia said."
""It is a sport of milliseconds, as you know," said Zee Hussain, head of global enterprise solutions at AT&T. "So the speed of data, the reliability of data, the latency, the security is just absolutely critical. If the data is not going, traversing, at the highest possible speed, and it's not on a secure and reliable path, that is absolutely without question the difference between winning and losing," Hussain said."
Race cars now carry about 750 sensors each, producing roughly 1.5 terabytes of data per car per race. Telemetry evolved from simple TV, throttle, brake, and steering feeds to hundreds of distinct data streams monitored by engineers on-site and in the factory. Immediate transfer of telemetry to the factory enables setup fine-tuning and real-time race-strategy decisions. Speed, reliability, latency, and security of data links are critical because milliseconds can determine race outcomes. Teams have increased personnel since 2017 yet reduced spending by prioritizing efficiency alongside performance. Typical cross‑continental latency can be as low as 0.3 seconds.
