Six GatesAir transmitters for ATSC 3.0 investigation at Humber College’s lab in Toronto
Among other key suppliers, GatesAir is holding up ATSC 3.0 investigations, testing and inplementation within the Broadcast-Broadband Convergence B²CLab infrastructure at Humber College in Toronto
The B²C Lab was established as North America’s first 100% front-facing industry research lab – a low-risk innovation environment to explore multi-sectoral applications of the ATSC 3.0 standard including convergence with 5G networks; now, the lab features six GatesAir Maxiva UHF transmitters. Lab’s work includes active participation with industry stakeholders and ATSC 3.0 technical teams, including the Tower Network Implementation team (TN-IT5), whose aim is to connect broadcast transmission towers to form an IP and 5G-based scalable and configurable Inter-Tower Communications Network (ITCN). The lab’s work incorporates joint research and development efforts with the Communications Research Center in Ottawa, the University of the Basque Country in Bilbao, Spain, and the Electronics and Telecommunications Research Institute in Seoul, South Korea.
Humber B²C Lab’s Engineering Manager, Willie Perez, has designed an OTA test bed that spans three tower sites to deliver NextGenTV services airing on UHF channels 22 and 28, with two GatesAir Maxiva transmitters at each site enabling content and IP data delivery. The configuration includes two UAXTE-3P-C, two UAXTE-2P-C, and two UAXTE-50 transmitters. The transmitters operate at low power (between 15 and 400 Watts TPO) and are well suited in leveraging ATSC 3.0’s physical layer to extend coverage from each tower site.
The Humber B²C Lab will soon add a seventh Maxiva transmitter to a fourth ATSC 3.0 experimental site atop the CN Tower in downtown Toronto, which Sushko says will expand the lab’s reach of testing services to approximately 25 percent of the Canada’s marketplace.
