Ericsson, Qualcomm and Thales to test 5G non-terrestrial networks

Ericsson, Qualcomm Technologies and French aerospace company Thales are planning for testing and validation of 5G non-terrestrial networks – for the first time.

The result could effectively mean that a future 5G smartphone could use 5G connectivity anywhere on Earth and provide complete global coverage for wideband data services, including places normally only covered by legacy satellite phone systems with limited data connectivity capabilities.

The benefits of 5G connectivity via low Earth Orbit (LEO) satellites are expected to include coverage in extreme geographies or remote areas across seas, oceans and other locations where terrestrial coverage is absent.

Widespread connectivity would boost 5G smartphone subscriber roaming service capabilities, as well as enabling global connectivity for transportation, energy and health sector 5G use cases.

The space-based network could also be used as back-up support to terrestrial networks in the event of major network outages or disasters.

“This testing and validation cooperation between Ericsson, Thales and Qualcomm Technologies will be a major milestone in the history of communications as the ultimate result could effectively mean that no matter where you are on Earth,” Erik Ekudden, chief technology officer of Ericsson, said.

“For 5G to fulfill on the promise of ubiquitous connectivity, it is imperative that it can deliver network coverage in areas where terrestrial cellular networks do not exist, whether that be over oceans or in remote areas,” John Smee, senior vice president, engineering, Qualcomm Technologies, said.

“The research collaboration with Ericsson and Qualcomm Technologies will demonstrate the belief of our companies that 5G non-terrestrial Networks will contribute to this revolution and will take network resiliency and security to the next level,” Philippe Keryer, executive vice president, strategy, research and technology, Thales, said.

The goal of the testing will be to validate various technology components needed to enable 5G non-terrestrial networks, including a 5G smartphone, satellite payload and 5G network pieces on the ground.

Ericsson plans to verify a 5G virtual RAN (vRAN) stack, modified to handle radio signals propagating (what happens to 5G radio waves travelling through the vacuum of space and the Earth’s atmosphere) via the fast-moving LEO satellites.

Thales plans to verify a 5G radio satellite payload suitable for deployment on LEO satellites, while Qualcomm Technologies plans to provide test phones verifying that 5G NTN can be accessed by future 5G smartphones.

Experts will use ground-based equipment to emulate the 5G radio propagation and time delays between an equipped satellite in orbit and connecting a 5G smartphone with the 5G radio access network at different places on the Earth’s surface.
