Samsung Electronics has selected the Anritsu Universal Wireless Test Set MT8870A for use on the mass-production lines of the Galaxy S25 – the Korean tech giant's next-generation smartphone, compliant with the Non-Terrestrial Networks (NTN) NB-IoT standard.

The test system is designed to ensure the much-hyped S25 meets the highest possible performance standards before leaving the factory, checking that the phone’s satellite connectivity works reliably in remote areas, tests 5G, Wi-Fi and Bluetooth in one streamlined process. This allows multiple devices to be tested at once, speeding up production without compromising quality. By integrating this advanced testing system, Samsung ensures the S25 is ready for real-world use straight off the production line – potentially a speedy advantage over industry rivals.

Smartphones supporting NTN NB-IoT can communicate through NTN using satellites and Unmanned Aircraft Systems (UAS). This makes reliable communication services possible in areas where terrestrial networks aren't available, including mountainous areas and areas without a wireless communication infrastructure. For the Galaxy S25, the flagship model of Samsung Electronics' MX division, the MT8870A provides a Tx/Rx performance test environment for wireless communications standards, including NTN NB-IoT.

The MT8870A offers up to four test ports for each platform, while enabling simultaneous testing on each port. In addition to NTN NB-IoT, the MT8870A also supports 5G NR, WLAN, and Bluetooth, making it an ideal tester for use with devices that must support these standards.

Anritsu will continue to provide test solutions for mass-produced NTN-compliant devices, potentially contributing to greater test efficiency and space savings in mass-production lines.
