What is a key feature of networks utilizing high-frequency radio waves?

Networks that utilize high-frequency radio waves are particularly noted for their ability to connect devices without relying on physical connections. This wireless capability allows communication over the airwaves, facilitating mobility and flexibility for users and devices. Such networks can efficiently support various applications, including mobile communications and Wi-Fi, enabling devices to exchange information across different locations without the restrictions imposed by cables.

In contrast, options such as low data transfer speed and limited range of connectivity do not reflect the strengths of high-frequency radio waves, which typically support high-speed data transmission and can cover considerable distances depending on the power of the transmitter and the technology used. Dependence on fiber optic technology is also unrelated, as fiber optics utilize light for data transmission, which is fundamentally different from radio wave technology. Therefore, the ability to connect devices without physical connections stands out as a defining and advantageous feature of networks that operate on high-frequency radio waves.
