Radio waves are examples of __________ communication.

In data communication, transmission media are broadly divided into two main categories: Guided (Wired) and Ungided (Wireless).

• Unguided Media: This media transmits electromagnetic waves without using a physical conductor. This is commonly known as wireless communication. Signals are broadcast through air, vacuum, or water and are available to anyone with a device capable of receiving them.

• Radio Waves: Radio waves use frequencies ranging from 3 kHz to 1 GHz. They are omnidirectional, meaning when an antenna transmits radio waves, they propagate in all directions. This makes them ideal for wide-area broadcasting systems like AM/FM radio, television, cellular networks, and Wi-Fi applications.
