Cat-M / Cat-1, sometimes known as LTE-M (LTE for Machines) is enhanced low power, wide-area (LPWA) technology supporting higher bandwidth, devices in motion, over-the-air updates, and voice functionality. Cat-M/Cat-1/LTE-Mis ideal for uses cases like wearables, facilities & consumable monitoring, and fleet & asset tracking.

Outside factors such as terrain, building structures, weather, and other conditions may interfere with actual service performance and availability.
