What Alternatives Can Be Used to Expand 5G Coverage

Qualcomm Technologies, Ericsson and French aerospace company Thales announced this week that they would be starting work together. Their intention is to make 5G connections available everywhere through the use of space. The partnership formed within months of 3GPP having been approved for satellite-driven 5G Non-Terrestrial Networks (5G NTNs). This global effort will be accomplished through the use of combined satellite and terrestrial connectivity.

“For 5G to fulfill the promise of ubiquitous connectivity, it is imperative that it can also deliver network coverage in areas where terrestrial cellular networks do not exist, whether that be over oceans or in remote areas,” said John Smee, senior vice president of engineering at Qualcomm. “Our planned research with Ericsson and Thales will kick off an important step in making this vital technology a reality. We are looking forward to what this collaboration can accomplish.”

The goal of the three companies is to assist with global network coverage, including in areas that currently do not have terrestrial network capabilities. They’ll use a low Earth orbit (LEO) satellite, which will allow coverage to be expanded to areas previously not able to receive service. This includes extreme terrain, as well as across seas and oceans. Additionally, the group is hoping that in the event of an emergency, satellite connectivity could be used in place of or as a backup to terrestrial networks.

“This testing and validation cooperation between Ericsson, Thales and Qualcomm Technologies will be a major milestone in the history of communications,” said Erik Ekudden, senior vice president and chief technology officer at Ericsson. “The ultimate result could effectively mean that no matter where you are on Earth – in the middle of an ocean or the remotest forest – high-end, secure and cost-effective connectivity will be available through collaborative 5G satellite and terrestrial connectivity.”

Smartphone focused testing is in the works in an emulated space environment in France. Validation of 5G NTN began with 3GPP’s announcement back in March. The tests are designed to allow the teams to discover what components are needed to enable 5G connectivity between smartphones, satellites and terrestrial 5G network segments. Ideally, they will ensure that 5G NTN can be supported through use of a network-enabled smartphone.

Each company has its own role to play. Qualcomm is providing the smartphones that will verify if 5G NTN can be accessed by 5G enabled devices. Ericsson will work with part of the testing phase and will handle the 5G virtual RAN stack that has been altered to handle radio waves through quick moving satellites. Thales’ responsibility will be to verify that the payload will be able to be distributed by the satellites themselves. 

“The deployment of 5G networks marks a step change for the telecoms industry. It is a game changer, not only in terms of business opportunities but also in the skills required to connect and protect billions of people and things,” said Philippe Keryer, executive vice president of strategy, research and technology at Thales. “Thales is deeply involved in it through the different activities of the Group. 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.”
