LEO Satellites for Backhaul


Telesat and Telefónica International Wholesale Services (TIWS) have recently completed a live in-orbit trial of a broad selection of applications on Telesat's Low Earth Orbit (LEO) Phase-1 satellite.

Applications tested over Telesat LEO resulted in observed round-trip latency of 30-60 microseconds without any packet loss. Test scenarios included:

  • High definition video streaming
  • Video conferencing
  • Remote desktop connection to manage a remote device
  • Virtual Private Network (VPN) connection
  • Bi-directional File Transfer Protocol (FTP) encrypted file transfers of 2 GB
  • Internet Protocol Security (IPSec) tunnel encryption with no reduction in the performance of the link
