Description: Low Power Wi-Fi refers to wireless technologies designed to consume less energy, allowing the connection of devices in environments where energy efficiency is crucial. This technology is especially relevant in the context of the Internet of Things (IoT), where numerous devices, such as sensors and actuators, require constant connectivity but have limitations regarding battery capacity. Low Power Wi-Fi employs advanced modulation techniques and optimized protocols that enable efficient data transmission, reducing energy consumption without sacrificing performance. Additionally, this technology can operate on specific frequencies that minimize interference and maximize coverage, which is essential in various applications across industries. In summary, Low Power Wi-Fi represents a significant advancement in wireless connectivity, facilitating the expansion of networks of connected devices while preserving battery life and reducing environmental impact.
History: The concept of Low Power Wi-Fi began to take shape in the mid-2010s when the proliferation of IoT devices drove the need for more energy-efficient connectivity solutions. In 2016, the Wi-Fi Alliance introduced the Wi-Fi HaLow (802.11ah) standard, specifically designed for low-power and long-range applications. This standard enables the connection of devices that require less energy, which has been fundamental for the development of technologies in various areas, including home automation and industrial automation.
Uses: Low Power Wi-Fi is primarily used in Internet of Things (IoT) applications, where devices such as environmental sensors, smart meters, and security systems require constant connectivity without high energy consumption. It is also applied in industrial environments for machinery monitoring and in homes for smart devices that need to remain connected to the network continuously.
Examples: A practical example of Low Power Wi-Fi use is in smart electricity meters, which efficiently send consumption data to utility companies. Another case is the use of temperature and humidity sensors in greenhouses, which monitor environmental conditions and send information through low-power Wi-Fi networks to optimize plant growth.
