Wi-Fi, specifically defined by the IEEE 802.11 standards, is the primary wireless communication standard used in home networks. It provides high-speed internet access and allows various devices such as smartphones, laptops, smart TVs, and IoT devices to connect to the same network wirelessly. The flexibility and convenience of Wi-Fi make it suitable for a wide range of devices, and it supports multiple connections simultaneously, which is essential for modern households that typically have multiple internet-connected devices.

In comparison, Bluetooth is designed for short-range communication between devices, such as connecting peripherals, but it does not have the same range or bandwidth capabilities as Wi-Fi. Zigbee is used primarily for low-power, low-data-rate applications like home automation and sensor networks, making it less suitable for general home internet access. Ethernet, while a reliable and fast wired connection, is not a wireless standard and thus cannot be used for wireless communication in home networks. Therefore, Wi-Fi stands out as the standard that best fulfills the requirements of wireless home networking.
