Addressing Critical Connectivity Gaps

Non-terrestrial network technology represents a breakthrough in addressing connectivity challenges across previously unreachable areas, ranging from mountainous terrain and remote islands to disaster-stricken regions. The NTN technology enables reaching areas where conventional communication infrastructure is unavailable.

As global demand intensifies for reliable communications in these challenging environments, NTN technology is positioned to become a cornerstone of next-generation 5G network architecture.

Building on Three Decades of Innovation

Anritsu says since establishing itself as a pioneer in mobile device testing solutions during the early 3G era, it has consistently delivered cutting-edge measurement technologies that advance the telecommunications industry. This latest enhancement to the MT8000A platform continues that tradition, providing manufacturers with the tools necessary to ensure superior 5G NR NTN device performance and reliability.

The expanded testing capabilities directly support the development of higher-quality 5G NR NTN devices, accelerating progress toward a truly connected society where seamless communication becomes possible regardless of location or circumstances.

Development Background

The communications industry is working to deploy widespread NTN services without requiring major changes to existing wireless devices. However, NTN technology faces two key challenges: propagation delay, caused by the time it takes for radio waves to reach the device, and Doppler shift, resulting from changes in the communication frequency due to satellite movement. Addressing these challenges only at the satellite side limits the stable communication range.

 To solve these challenges and support broader and more stable communication capabilities, the 3GPP international standardisation body has defined new device-side specifications in Release 17.

Product Outline

Radio Communication Test Station MT8000A

The MT8000A test instrument is designed primarily for developing 5G devices meeting 3GPP standards. It supports protocol tests to verify that 5G devices establish proper connections to the network and RF tests to evaluate 5G device ease of connectivity. Anritsu supports test conditions that comply with 3GPP Release 17 and later. The MT8000A can simulate propagation delay and Doppler shift in 5G NR NTN environments to facilitate development of 5G NR NTN devices meeting the unique challenges of the satellite communications.
