A high throughput modem from Gilat Satellite Networks has enabled the first ever demonstration of 5G services over a Low Earth Orbit or LEO satellite. The successful test was conducted with a tier-1 European operator last month using Telesat's Phase 1 LEO satellite connected to the University of Surrey's 5G test bed network.
The demonstration included video chatting, web browsing and simultaneous streaming of up to 8K video. The project team also transferred 4K video to the edge of the 5G network, which is a key 5G future use case. Live testing of these content rich data streams was achieved using 5G cellular technology that offers many benefits but which requires an advanced backhaul solution that can quickly and cost effectively extend these benefits to subscribers beyond major cities. The testing confirmed that this required 5G backhaul can be provided by Gilat modem technology working with Telesat's Phase 1 LEO satellite.
"This demonstration confirms that Telesat's state-of-the-art LEO architecture delivers on the promise of latency sensitive and high bit rate applications such as in 5G connectivity,” said Michel Forest, Director of Engineering.
