Low-power 2.38-GHz products are a category of wireless communication devices typically used in industrial, medical, and IoT applications. These products are often developed by companies specializing in RF (Radio Frequency) and microwave technology, such as Texas Instruments (USA), STMicroelectronics (Switzerland), or Nordic Semiconductor (Norway). They operate in the 2.38-GHz ISM (Industrial, Scientific, and Medical) band, offering low-power solutions for short-range wireless connectivity, sensor networks, and embedded systems. Key products include transceivers, modules, and system-on-chip (SoC) designs, enabling energy-efficient communication for wearables, smart home devices, and industrial automation. Brands like Nordic's nRF series or TI's CC2540 are prominent examples in this niche.
