HDwireless provides the coverage of “Wings for Life”

Radio Technology with a Relay Aircraft and GPS Antenna Tracker for the World Run in Olten

It is May 7, 2017. A Piper Seneca V is flying over the Canton of Solothurn in Switzerland at 12:50 p.m. The aircraft originally took off in Germany and is now circling over the city of Olten. In a few minutes, the aircraft is set to receive and transmit high-frequency radio signals. At 1 p.m. on the dot, the fourth “Wings for Life World Run” gets underway in Olten. Around 4,000 runners set off on what is a special run with a mobile finishing line, the so-called “catcher car.” More than 150,000 runners worldwide are taking part in the simultaneous global charity race, which is broadcast live. The company HDwireless from Mechernich, close to Cologne, is getting involved for the fourth time too and is providing the wireless camera transmission as well as taking care of the radio production and transmission of GPS positional information in Olten. Precise planning and radio coordination was necessary during the preparation phase to enable them to provide complete radio transmission over the 80 km-long running course. When it comes to transmissions across such an expansive area, bi-directional radio is operated via a flying relay station. This offers many benefits, such as the continuous and cost-efficient flight for the entire duration of the event without the need for intermediate landings, as well as not being at the mercy of the weather conditions at high altitudes, which enables outstanding transmission quality. The relay aircraft receives video signals from wireless cameras, which camera operators on two motorbikes use to provide live coverage from the course. The signals are processed on board the aircraft and transmitted without interruption via a downlink array to the stationary ground antennas, which are located on top of a 40-meter-high cherry picker. Perfect reception is ensured by an antenna system that is always pointing toward the aircraft. For the first time, HDwireless is launching a recently designed in-house development for the World Run. CEO Patrick Nußbaum explained: “Our new GPS antenna tracker aligns the antennas according to the GPS position of the relay plane, which, in turn, is guided by the GPS information transmitted by the motorbikes. All GPS information from the mobile transmission/receiving stations can be controlled and positioned via our on-site data network, which we also developed ourselves. It is possible to check the GPS positions at any time, as you can view them using Google Earth.” All radio signals are received in the “Wireless Video Village” by the high-frequency ground antennas in the “HDwireless RF1” production car. The antenna signal is fed, decoded and transmitted to the broadcaster’s OB car using fiber-optic cables. The GPS information is read from the data network and used to control the GPS antenna tracker. At the same time, the RF1 is the nerve center of the operation, with its own communications network and transmission cells for the team and radio production. Patrick Nußbaum summed it up as follows: “The HDwireless team is the full-service provider for video, audio and communications nowadays.” After running 68.11 km, the winner is eventually overtaken by the catcher car on the running course in Olten. The run is over and the relay aircraft with the HDwireless high-frequency transmission technology on board returns to Germany to land after having been in the air for six hours.

HDwireless develops GPS antenna tracker

Greater reach for wireless camera transmissions

Sports events such as marathons or bicycle races naturally cover vast areas. Uninterrupted and at the same time attractive live coverage for TV and Internet streaming therefore presents a demanding challenge. Not only will signals have to transmit over great distances to the mobile unit, but the course – depending on the topography – may present obstructions influencing the transmission. It is the live pictures that should present any athletic contest the viewers at close range. Quite frequently several cameramen on motorbikes will transmit in real time from the route. The broadcasting and event-supplier HDwireless of Mechernich specializes in such tasks. This business has the necessary know-how and technology, as well as long time experience with professional wireless transmission at great distances, even under the usage of helicopters and aircraft. In future distances and transmission security will be increased even further. This enables even greater transmissions of more widespread sports events, assuring at the same time stable transmission at efficient costs. In the center of this in-house development stands the prototype of the GPS antenna tracker with its free swiveling antenna array. Sebastien Coat, software programmer at HDwireless explains the computer assisted tracker steering: “With our software the GPS tracker continually adjusts the direction of the mobile or airborne transmitters. The position data supply steadily determines the optimal direction which means an enormous increase of the operating range“. HDwireless has been developing and producing wireless systems and individual solutions for high frequency radio transmission for many years. “Our products are developed from practice. We bring together concrete market demands with our longstanding know-how – starting with development via construction up to manufacturing”, Patrick Nussbaum describes the HDwireless philosophy. For the prototype of the GPS antenna tracker this means an optimum of orientation of the tracking system toward the integrated RF-transmission technology of the manufacturer Vislink. In order to perfectly control the operation, and for the exact viewing for the customer the GPS tracking points can be visualized via Google Earth. The GPS antenna tracker is a well thought out, productive system, and it will be available in future in the product portfolio of HDwireless as an efficient technology to increase radio ranges.

Fiberglass Systems Solution for Broadcasting in vast areas

The importance of wireless cameras for broadcasting and events is perpetually increasing. The requirements regarding efficiency of wireless camera systems that cover vast areas are on the rise, especially for live sports events. Patrick Nussbaum, CEO HDwireless, comments: „When planning complex wireless transmissions we do not only use radio links. On the one hand we calculate optimal sites for RF-antennas, and on the other we connect them by fiberglass cross-links, depending on the requirements. For implementation we depend on system components like RFiber”. Patrick Nussbaum knows: in the long run a stable video signal at the final transmission chain is the only thing that counts. With our in-house HDwireless developed  product RFiber, for example, high or intermediate frequency signal can be transported without loss for several kilometers before they will be demodulated by receivers and forwarded to decoders. With this technology signals from various antenna sites can be linked via fiberglass inside one mobile production unit – such as the HDwireless RF1 or a mobile editing. The software „HDwireless System Overview“ offers effective observation of long or linked wireless transmissions. This way each RFiber-unit on site can be regulated transparently and intuitively. Sebastien Coat, HDwireless software developer, explains: „We define the functional range of all our hard- and software based on longstanding and broad experience with the projects. This software enables the operator not only to control the RFiber units but also the demodulators and decoders within the fiberglass network”. Within the dry-hire rental HDwireless offers all components for high frequency wireless and fiberglass transmission. All our clientele, wanting to rent equipment may choose from fiberglass systems with Lemo connection, or, alternately single fiberglass for all connectors. RFiber comes in robust in- and outdoor units, and was developed for professional broadcasting.

HDwireless realizes Live-Broadcast from the Istanbul-Marathon

Complex wireless radio transmission in Turkish TV

On the occasion of the “Istanbul Eurasia Marathon 2016” the participating runners looked on the November 13th toward the Bosporus bridge, ready to start. Three helicopters where circling above, prepared for the live transmission of the world’s only intercontinental Marathon. For suspenseful and up-close live images of the runners cameras were mounted on helicopters and motorbikes. The German company HDwireless from Mechernich near Cologne had been hired by the Turkish Broadcasting service “Kamera Teknik” and was responsible for this extensive transmission; HDwireless plans and performs wireless camera projects worldwide.  The Turkish broadcasting service “Kamera Teknik” decided in favor of HDwireless to operate with three helicopters, one with a Cineflex camera system, and one with relay function, the third one was equipped with Cineflex camera system and RF relay technology. The two motorbikes had their visual angle directed at the leading runners. The third bike transmitted live impressions from the entire field of runners to the helicopter. Patrick Nussbaum, CEO of HDwireless comments: “We equipped two so-called relay-helicopters with receiving and transmitting technology in order to enable us to still send dependable images – despite the considerable distance between the bikes. At the same time we procured a stable signal dependability with redundant relay stations in the air”. The helicopters transmitted the RF signals they received from the bike-cameras as ASI transport stream to a cross-linked antenna-array on the ground. This is where the helicopters as well sent their live aerial images of the sports event. For this, the helicopters had been equipped with a gimbal mounted Cineflex camera system.  Summing up, HDwireless supplied the host broadcaster with five live signals from the race to the OB-van for live transmission on Turkish TV; at the same time, HDwireless was responsible for the entire team-radio communication from the ground to all airborne stations.
