What technology is used for wireless networking?

Wireless networking primarily relies on radio frequency technology to transmit data without the need for physical connections. Bluetooth is a specific protocol that enables wireless communication over short distances, typically between devices such as smartphones, tablets, and peripheral devices like keyboards and headphones. It operates on the 2.4 GHz band and is designed for low power consumption, making it suitable for applications where devices need to communicate wirelessly with minimal energy usage.

In contrast, fiber optics, coaxial cable, and Ethernet are all wired technologies. Fiber optics use light to transmit data over glass or plastic fibers, offering high-speed connections over long distances. Coaxial cable consists of a central conductor and insulation and is commonly used for cable television and internet services. Ethernet, a standard for wired networking, involves using twisted-pair or fiber optic cabling to connect devices within a network.

Since the question specifically asks about wireless networking technology, Bluetooth stands out as the correct answer due to its wireless capabilities.
