Telesat, TIM Brasil successfully test LEO satellite backhaul

The global satellite operator Telesat and TIM Brasil, the Brazilian subsidiary of Telecom Italia, completed in-orbit 4G mobile data backhaul testing using Telesat's Phase 1 low earth orbit (LEO) satellite.

According to a joint press release, the first-of-its-kind LEO backhaul testing in Brazil was conducted with TIM Brasil’s Innovation Department staff at their teleport in Rio de Janeiro, leveraging an 85 cm Intellian parabolic antenna to uplink and downlink to the LEO satellite.

It said it achieved an average of 38 milliseconds of round-trip latency. "All applications tested ran efficiently without interference, fading or performance breaks throughout the tests, including 1080p YouTube video streaming, video conferencing, WhatsApp voice over LTE and interface compatibility," said the release.

The resulting low latency represents a compelling opportunity for operators like TIM Brasil to expand their mobile and Internet services, it added.

"Brazil has very good 4G coverage in population centers, but remote communities usually cannot cost-effectively be connected to the core network through fibre or additional cell towers due to long distances and difficult terrain. These tests highlight how Telesat Lightspeed can bring multiple Gbps of affordable, high-performance backhaul connectivity to connect many underserved regions and reduce the digital divide in Brazil," noted the release.

The release said that with its innovative DNA, TIM Brasil is committed to achieving 100% 4G network coverage by 2023 and has been a leader in 5G testing in Brazil, even before the technology became a reality in the country. To this end, the operator opened its innovation laboratory, TIM Lab, in 2019 to test new technologies for its next-generation mobile networks.

Mauro Wajnberg, General Manager, Telesat Brasil said: “Telesat Lightspeed backhaul connectivity will be transformative for Mobile Network Operators like TIM Brasil, who are seeking cost-effective, enterprise-grade backhaul solutions to affordably connect all potential subscribers, no matter where they live.”

“Through this testing program, we believe Telesat Lightspeed is a promising technology to expand the geographic reach of our 4G/LTE and 5G networks,” said Silmar Palmeira, Director of Architecture, Innovation, and Technology at TIM Brasil.
