Numerous wireless camera systems broadcasting live images from vehicles
The IAA in Frankfurt is the leading trade fair in the automotive industry. Manufacturers present their vehicle studies, prototypes and new models during numerous press conferences and special events. The live broadcast on LED screens or directly on the internet is an important part of these events. Broadcasting technology featuring professional cameras, switchers, periphery and OB trucks is often used. Live images from moving vehicles are often a key aspect of these presentations. The wireless camera specialist HDwireless from Mechernich near Cologne is specialized in exactly this field. This year, it installed a total of 15 onboard cameras and imaging systems in vehicles with very different requirements for a number of IAA exhibitors. Almost invisible HD cameras showed the interior of an autonomously driving prototype during a press conference. Vehicles driving along a test track were fitted with wireless cameras, which broadcast subjective camera perspectives.
Live images of driving and braking maneuvers from test cars in the outdoor arena were broadcast live to viewers on a large LED screen. Tanguy Heintz, Project Manager at HDwireless explained: “Although the applications are different, the implementation follows a standard procedure: All HDwireless onboard cameras transmitted live HD images to their receiving stations using high-frequency radio signals. Our customers attach utmost importance to reliable and stable signal qualities, which can only be ensured by using suitable transmission technology, carrying out detailed planning and employing a frequency network coordinated with the BNetzA.” As part of frequency planning and coordination, HDwireless selects frequencies for projects, applies for them and gets the respective license from the authorities, e.g. for temporary use at trade fair arenas. Tanguy Heintz went on to state: “It’s not uncommon for us to be able to measure several hundred active frequencies (simultaneously) between 450 MHz and 7 GHz in exhibition halls. This demonstrates the complex requirements with regard to the operational reliability of live image transmission for trade fair projects featuring discerning national and international target groups”.
