Telesat, a leading global satellite operator, and Telefónica International Wholesale Services (TIWS), the international wholesale services provider of the Telefónica Group, have completed live in-orbit testing across a wide range of applications on Telesat’s Low Earth Orbit (LEO) Phase 1 satellite.
With a mission to increase agility and improve operational efficiencies, TIWS partnered with Telesat on a rigorous testing campaign to explore the performance and feasibility of leveraging LEO satellites for high-end services. Testing demonstrated that Telesat LEO could be a viable option for wireless backhaul and presents a substantial improvement in performance over geostationary orbit (GEO) links, without the use of compression or TCP acceleration techniques that are typically required in 650ms latency GEO environments.
Applications tested over Telesat LEO resulted in observed round trip latency of 30-60 msec without any packet loss. Test scenarios included: High definition video streaming, without interruption; Video conference with teams, demonstrating consistent fluidity of movement and voice transmission with user experience matching terrestrial and cellular connections; Remote desktop connection to seamlessly manage a remote computer; VPN connection without any delay or outages; FTP encrypted file transfers of 2 GB in both directions; and IPSec tunnel encryption with no reduction in the performance of the link.
Gustavo Arditti, TIWS Satellite Business Unit Director
Across every application tested, Telesat LEO delivered an outstanding performance, with significant improvements over what we can achieve via GEO satellites today.
Erwin Hudson, VP, Telesat LEO
The ability to demonstrate fibre-like performance via satellite across a number of applications that perform poorly on GEO satellite backhaul is a testament to the capabilities of our Telesat LEO network.
