Wireless is an expression in the field of telecommunications.
It describes that electromagnetic waves and no cable transmit a signal over a communication path.
Some surveillance devices, such as a burglar alarm, rely on acoustic waves that are at frequencies outside the human hearing range.
The first transmitters used in radiotelegraphy (Morse code) in the early 20th century.
Later, thanks to modulation, speech and music could also be transmitted wirelessly. The medium is well known and is called radio.
The term wireless has revived through television, fax, data communications, and the effective use of a broader range of the spectrum.

What are the Different Types of Wireless?
Wireless can divide into:
- Firstly, it means the operation of devices or systems in the home or offices.
- And also, It is also how equipment describes that connects to the Internet with individual modems.
- The use of devices or systems installed on motorized, moving companions.
- And also, Examples include car phones and personal communications services ( PCS ). Smartphones have primarily replaced these systems.
- The operation of autonomous devices works with a battery.
- They can use outside the office, home, or vehicle. For example, in the past, these were cell phones and PCS units. Nowadays, most users have a smartphone.
- The use of devices transmits data using IR ( infrared ) radiation.
- And also, Control systems with this technology are limited in terms of range for communication.
