Low-rate wireless refers to a class of wireless communication technologies designed for low data throughput, low power consumption, and low cost per device. These systems typically transmit small packets at data rates ranging from a few bits per second up to tens of kilobits per second, enabling very long battery life and inexpensive hardware. They are widely used in Internet of Things (IoT) and automation scenarios where sensors, actuators, and wearables require intermittent data updates rather than high-bandwidth streaming.

Technologies in this category include standards and protocols such as IEEE 802.15.4-based networks (including Zigbee and Thread), Bluetooth Low Energy, and various low-power wide-area networks like LoRaWAN and Sigfox, as well as cellular NB-IoT. Many operate in unlicensed spectrum (for example 2.4 GHz or sub-GHz bands), employ simple modulation and robust error handling, and rely on duty cycling or scheduled transmissions to conserve energy. Network topologies commonly observed are star and mesh, with mesh-based approaches enabling larger coverage and redundancy.

Key considerations in deploying low-rate wireless systems include power availability, range requirements, interference from other devices in shared bands, security, and interoperability among devices and platforms. As IoT adoption grows, these technologies continue to evolve with improvements in energy efficiency, reliability, and standardization to support scalable, low-cost networks. Future developments focus on greater integration with IP-based networks, improved device authentication, and enhanced resilience in dense deployments.
