Live Pit Wall

Live timing · test day
Timing, onboard video and CAN all arrive on the same bonded LTE uplink — one link off the car. Health per car in the UPLINK panel below.

Glass to glass · pit wall
Two modems, two carriers, one stream. A racetrack is the worst RF environment there is — tens of thousands of phones on the same towers and a car crossing cells at 240 km/h. Bonding is why the feed survives it: when one carrier collapses the other takes its share inside a second, and the picture never breaks.

Uplink 12.4 Mb/s off the car, 2,858 viewers served. Add ten thousand fans and the car still sends 12.4 Mb/s — the edge does the multiplying, so the pit wall stays sub-2 s while the public feed runs on standard HLS with no viewer ceiling.
