Which statement best describes radio waves in networking?

• A. They require physical cables.
• B. They provide wireless communication and typically have shorter range.
• C. They offer unlimited bandwidth.
• D. They are used for fiber upgrades.

Answer: (B)

Radio waves in networking enable wireless communication, like Wi‑Fi, Bluetooth, and cellular links. The best description is that they provide wireless communication and typically have shorter range, since signals in the air are affected by distance, obstacles, and interference. They do not offer unlimited bandwidth—the capacity is limited by the radio channel and regulatory rules, and it varies with conditions. They’re not used for fiber upgrades, because fiber relies on light through glass, though wireless links can backhaul network connections.
