Single-mode LTE Telecom Chipsets
Altair Semiconductor develops cellular IoT chipsets that provide low-power, secure connectivity for connected devices such as smart utility meters, asset trackers, wearables, vehicle telematics, smart-city infrastructure, home appliances, and industrial IoT systems. Its LTE Cat-M and NB-IoT platforms, including the ALT1250 and ALT1350, integrate modem, RF, security, iSIM, and low-power processing capabilities to help device makers connect products to cellular networks with lower power consumption and smaller hardware footprints.
Founded in Israel in 2005, Altair was acquired by Sony in 2016 and later operated as Sony Semiconductor Israel. In 2026, the company completed a spinout from Sony Semiconductor Solutions and returned to operating under the Altair Semiconductor name, with Sony retaining a minority stake.
