Low-power 2.15-GHz products are not a specific brand but a category of electronic components designed for energy-efficient wireless communication and sensing applications. These products are typically developed by various companies specializing in RF (Radio Frequency) and IoT (Internet of Things) technologies. For instance, companies like Texas Instruments (USA), Nordic Semiconductor (Norway), and STMicroelectronics (Switzerland) offer low-power 2.15-GHz solutions, including transceivers, modules, and SoCs (System-on-Chips). These products serve industries such as industrial automation, smart metering, and wearable technology, enabling long-range, low-energy connectivity for devices like sensors, beacons, and asset trackers. The 2.15-GHz frequency band is often chosen for its balance between range and power efficiency, making it ideal for IoT deployments.
