Question: 1 / 400

Which technology uses radio waves to transmit data signals over short distances?

Wi-Fi

Bluetooth

Bluetooth is specifically designed for short-range communication, typically within a distance of about 30 feet (10 meters). It utilizes radio waves to transmit data between devices such as smartphones, headphones, and other peripherals. The technology operates in the 2.4 GHz ISM band, which is a part of the radio frequency spectrum reserved for unlicensed use, making it widely accessible for various devices.

This capability makes Bluetooth particularly effective for personal area networks (PANs), allowing seamless connections between numerous devices wirelessly without extensive setup or configuration. The simplicity and efficiency of Bluetooth technology in establishing connections at short distances is why it is the correct choice in this context.
