Despite the focus on building a backhaul for the 5G network, operators have not abandoned their commitment to extend the 4G network to several places that are difficult to access by other technologies, such as fiber optics. .
TIM Brasil, this Thursday afternoon (20), announced the completion of a series of tests with the equipment of the Canadian operator Telesat. The project aims to provide connectivity via a low orbit satellite network (LEO) for greater network coverage and reliability.
The tests were spread over five days and showed promising results with the LEO Phase 1 satellite. TIM’s innovation area teams, in partnership with Telesat developers, measured good performance in mobile network applications. 4G using satellites, reaching 38 ms average latency.
Among the applications tested, scenarios of high quality video streaming, video calling and VoLTE technology via WhatsApp were found to be effective and without interruption or interference from other signals. The test campaign adopted an 85cm Intellian satellite dish for the transmission and reception of link data.
In a statement, Telesat highlighted the wide coverage of the 4G network in population centers, such as metropolitan areas and large Brazilian cities, but this technology may not reach areas that are difficult to access or very far from the center of the network. As a result, satellite applications are expected to benefit a significant portion of the population.
For Silmar Palmeira, of TIM Brasil, the conclusion of this test program showed that Telesat Lightspeed technology holds promise for greater geographic reach of the operator’s 4G / LTE and 5G networks.
The performance of Telesat’s LEO Phase 1 satellite provided mobile experiences comparable to our terrestrial networks, and we believe that Telesat Lightspeed, with a hardware ecosystem optimized for mobile devices, has the potential to become a central part of our future infrastructure. .

It also discusses the relevant profitability of Canadian technology, which delivers high speed in an affordable and high-performance network to connect underserved regions and reduce digital inequalities in Brazil.
Telesat says its constellation of low-orbiting satellites will take shape from launches in approximately two years, creating a unified and stable network for various applications around the world.
