Seamless Air Alliance, the developer of global standards for Inflight Connectivity (IFC), has announced it will ‘foster the development and integration’ of 3GPP specified 5G NTN into the aviation sector to enable future seamless connectivity between terrestrial and non-terrestrial satellite networks.

Historically, mobile satellite services have leveraged proprietary technologies that hinder integration with terrestrial networks. The lack of interoperability between different satellite providers’ IFC offerings, due to varying modem, antenna, and frequencies, has posed significant challenges for airlines.

To address these issues, the SAA formed a specialised NTN Working Group to ensure 5G NTN considers the unique challenges and requirements of the aviation industry. The group has released its first white paper, which outlines key factors and considerations for applying 5G NTN to IFC and the opportunity for a significant evolution toward a fully interoperable solution for aviation connectivity.

“5G NTN provides an opportunity to harmonies IFC standards and overcome the limitations of proprietary satellite technologies, which prevents airlines from pursuing technology upgrades and inhibits the interchangeability of equipment,” stated Olivier Hauw, Fast Track Leader Connectivity at Airbus and co-chair of the SAA NTN Working Group.
