Low-power 2.16-GHz products are not a specific brand but rather a category of electronic components designed for energy-efficient applications in the industrial and telecommunications sectors. These products typically include RF (Radio Frequency) modules, transceivers, and sensors optimized for low power consumption while operating at 2.16 GHz. They are commonly used in IoT (Internet of Things), wireless communication, and automation systems. Companies like Texas Instruments (USA), STMicroelectronics (Switzerland/France), and NXP Semiconductors (Netherlands) are among the leading manufacturers offering such solutions. These components cater to industries requiring reliable, low-power wireless connectivity, such as smart manufacturing, healthcare devices, and smart infrastructure.
