Radio is the wireless transmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light, in the radio frequency range, from about 30 kHz to 300 GHz. These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

In an industrial or industry context, "radio" refers to a system of wireless communication that uses electromagnetic waves to transmit and receive information. Radios can be used for a variety of purposes, including voice and data communication, navigation, and remote control of machinery and equipment.

Some examples of the use of radios in industry include:

1. Mobile communication - radios are used for voice and data communication in a variety of mobile applications, such as cellular phones, two-way radios, and satellite phones.
2. Industrial automation - radios are used for wireless control of machinery and equipment, such as cranes, robots, and unmanned aerial vehicles (UAVs).
3. Navigation - radios are used in GPS and other navigation systems to determine position, velocity, and time.
4. Remote monitoring - radios are used to transmit data from remote sensors, such as weather stations, to central control systems.
5. Emergency response - radios are used by emergency services, such as police, fire, and ambulance, for voice communication and coordination.

Radio technology has a wide range of applications in industry and plays a critical role in the functioning of modern economies and societies. The development and use of radio technology is subject to ongoing advances in technology and regulation, and is increasingly integrated with other forms of communication, such as the Internet and satellite systems.
