About
Altair Semiconductor specializes in designing low-powered and highly integrated cellular Internet of Things (IoT) chips, such as Long Term Evolution (LTE) CAT-M and NB-IoT modems and systems-on-chips. These semiconductors are primarily used for machine-to-machine communications in devices like sensors, smart meters, asset trackers, wearable gadgets, and vehicle telematics. The company's platforms 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. Altair is also developing digital signal processors that integrate AI directly into sensors and 5G-capable enhanced Reduced Capability (eRedCap) modems.
