McLean – October 14, 2026 -- Altair Semiconductor is integrating Iridium NTN Direct into its ALT1350 and next-generation ALT1550 IoT chipset platforms, so device makers can add satellite connectivity without a separate satellite modem, Iridium Communications (Nasdaq: IRDM) announced.
Single chipset combines terrestrial cellular and Iridium satellite links
Device manufacturers, module makers and mobile network operators (MNOs) get terrestrial cellular IoT and Iridium satellite connectivity on one chip. Iridium NTN Direct is a 3GPP standards-based non-terrestrial network (NTN) service. It runs on Iridium's low Earth orbit (LEO) constellation and globally coordinated L-band spectrum, and supports NB-IoT and direct-to-device (D2D) applications on compatible chipsets.
