Wi-Fi, short for Wireless Fidelity, is a widely used wireless networking technology that allows devices to connect to the internet and communicate with each other wirelessly. It operates on the IEEE 802.11 standards and uses radio waves to transmit data between devices within a local area network (LAN). Wi-Fi is prevalent in homes, businesses, public spaces, and virtually all modern electronic devices, providing high-speed internet access and enabling seamless connectivity. 

Wi-Fi HaLow, also known as 802.11ah, is an extension of traditional Wi-Fi technology designed specifically for IoT and low-power, long-range applications. It operates in the sub-1 GHz frequency band, offering longer range and better penetration through walls and obstacles compared to standard Wi-Fi frequencies. Wi-Fi HaLow is optimized for low-power consumption, making it suitable for battery-operated devices such as sensors, smart meters, and connected appliances. It provides reliable connectivity over extended distances, making it ideal for IoT deployments in challenging environments like smart cities, agricultural fields, and industrial facilities.
