Broadcast RF supplied RF facilities for the complex wireless camera coverage of the Standard Chartered Marathon Singapore 2015. New levels of coverage were achieved over the highly diverse geography of the 42km race. The marathon route is challenging for runners and production teams as it runs through iconic sites of central Singapore, including Orchard Road, Gardens by the Bay, East Coast Park, Singapore Sports Hub and parts of the Singapore Formula One track.
Ground-based receive set ups are essential for such events in Singapore because the use of relay aircraft is highly restricted. Broadcast RF specialise in such deployments, using superior technology to cover long-distance sporting events of any kind worldwide.
Live video transmission from multiple city sites can be difficult due to numerous high-rise buildings, underpasses, and sometimes dense foliage. Even more difficult are coastal sections, which often include numerous trees, low-rise structures, and limited reflective surfaces. The Singapore Marathon included both, but despite those obstacles, Broadcast RF’s setup achieved flawless video coverage over 99 percent of the course.
Broadcast RF Sales Director Chris Brandrick said, “The only reason were weren’t able to achieve 100 percent coverage is that the race goes through a 1.1 km tunnel, and even then we only lost 400 metres. The reliability and quality of the video links was remarkable.”
Broadcast RF supplied transmit equipment for three live chase motorbikes and installed receive sites in four locations along the course, including the roofs of Marina Bay Sands Hotel and Suntec Tower 4, as well as two receive sites in the East Coast Park area. Suntec Tower 4 was used as the main receive hub, the bike signals received at the other three locations were sent on to Suntec Tower 4 via point-to-point microwave links. An intelligent switching system at the main hub was used to constantly monitor the receive quality for all three bikes at each of the four receive locations and to automatically switch to the best receive location for each bike.
Broadcast RF Project Manager Ben Hawker said, “This cellular switching system played an essential part in achieving unprecedented HD coverage of this challenging race.”
