LiteOS is a lightweight real-time operating system (RTOS) developed by Huawei for Internet of Things (IoT) devices. It is an open source, POSIX compliant operating system that can run on devices with very limited resources, such as sensors, wearables, smart meters, smart lighting, etc. It has a kernel size of under 10 KB and can run on an AA battery for up to five years !

LiteOS aims to make IoT devices smarter by providing a comprehensive software platform that integrates an IoT operating system and middleware. It supports various communication protocols, such as Wi-Fi, Bluetooth, ZigBee, LoRa, NB-IoT, etc. It also provides a cloud-device interconnection framework that simplifies application development and deployment. LiteOS can be widely used by individuals, families, and businesses for various IoT scenarios, such as smart home, smart parking, smart metering, etc .

LiteOS is not only a technical innovation but also a business innovation. It leverages Huawei’s successful experience in the consumer, operator, and enterprise domains and helps its partners achieve business success by offering low-cost, low-power consumption, fast startup, and smart coordination solutions. LiteOS is also an open and win-win platform that welcomes developers and partners to join the IoT ecosystem and create value together.
