Mercedes F1 to use Qualcomm 5 GHz WiFi for its tire data

In Formula 1 you need more of everything. More speed, more grip, more hospitality, more money. And you need data, reams and reams of data. The Mercedes-AMG Formula 1 team – the guys with the silver cars driven by 2015 F1 champion Lewis Hamilton and his teammate Nico Rosberg – need so much information that they've teamed with Qualcomm to wirelessly upload thermal imaging data of its tires. During a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Live telemetry has been a feature of Formula 1 for 20 years, though there are more restrictions on it than in the past. (In the days leading up to last weekend's United States Grand Prix in Texas, Formula 1 major domo Bernie Ecclestone said that F1 needs to cease being an engineering war and return more responsibility to the drivers.) Nevertheless, F1 teams gather vast amounts of data during a race weekend, particularly in practice sessions during which restrictions on what they can upload from cars – from engine/power unit parameters to aerodynamic loads – are less prohibitive. For example, during a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Mercedes F1 technical director Paddy Lowe points out that the standard telemetry system simply doesn't have the bandwidth to handle the thermal tire imaging data that the onboard thermal cameras generate. Why do you want a thermal video of the tires? Because it tells the engineers and drivers precisely how much temperature there is across the surface of a tire during a lap, in corners and on the straights. It also indicates how quickly the tires come up to temperature and when they potentially overheat. Understanding the temperature variations allows the team to set the cars up optimally for grip and tire life during a stint. Qualcomm's system works with the race cars like this: Each car has forward- and rear-facing cameras in a winglet mounted on the left side of the engine intake behind the driver's head, which continuously record thermal images of the tires. As a Mercedes enters the pit lane, it passes a Qualcomm 802.11ac WiFi receiver to which it uploads the thermal data. As the car nears the garage, another receiver takes over the upload. Several Qualcomm Snapdragon 805 processors crunch the raw data as it uploads. The data is encrypted – there are always prying eyes in Formula 1.

2015 Mexican Grand Prix is a lot like old times

The last time Formula One visited Mexico, in 1992, 26 cars powered by eight engine manufacturers (counting Honda and Mugen-Honda separately) lined up on the grid; it would have been nine engine makers but the Brabham-Judd cars failed to qualify. In 1992 Lewis Hamilton was seven years old, Sebastian Vettel was five, Max Verstappen was still five years away from being born. Two of the current Sky Sports F1 commentary team, Martin Brundle and Johnny Herbert, were drivers. The starting three were Nigel Mansell on pole – 39 years old, this the year he'd win his only World Championship – and Riccardo Patrese both driving Williams-Renault cars, followed by Michael Schumacher in a Benetton-Ford. Only 13 of the 26 starters would finish. The circuit is has been reworked to today's safer standards, the track surface is brand new and slippery, but the atmosphere and packed grandstands haven't changed. Nico Rosberg was another point of consistency, scoring pole position for the fourth race in a row to beat his now-World-Champion teammate Hamilton by almost two-tenths of a second. The last time Rosberg turned pole position into a victory? The Spanish Grand Prix back in May. Vettel locked up third for Ferrari, followed by the Infiniti Red Bull Racing duo of Daniil Kvyat and Daniel Ricciardo. Williams went two-up as well, Valtteri Bottas in sixth ahead of Felipe Massa in seventh. Max Verstappen turned in a great late lap to reserve eighth place, Sergio Perez did all he could in front of his home crowd to get ninth, teammate Nico Hulkenberg the caboose in the top ten. In that 1992 race the first three on the grid finished the race in the same order after Mansell dominated, and it was almost the same in 2015. If Rosberg had driven the whole season like he drove today the Driver's World Championship would still be up for grabs. He got a great start and held his line through the first corner, coming out ahead of Hamilton through the initial kinks, pulling away as soon as he got to the straight. Hamilton was never more than a few seconds behind, but every time the Brit inched closer the German found a few more tenths to keep his distance. The field got bunched up when the Safety Car came out on Lap 53 after Vettel spun and got stuck in the barriers, but Rosberg handled the restart perfectly. Both drivers made small mistakes in the last few laps while driving on the edge, but Rosberg earned a strong victory, crossing the line two seconds ahead of his teammate.
