Wireless Communication Technologies
What is it?
Wireless communication technologies are solutions that enable the transportation of voice and data without using any wires or cables.
This type of communication does not involve physical connection. Therefore, data is passed on from sending devices to intermediate and end-user devices through the broadcast of electromagnetic signals.
It serves to transfer signals at distances ranging from several meters to thousands of kilometers.
How does it work?
The functioning of wireless communication relies on a sending device’s and a receiving device’s capabilities. A sending device must be able to propagate wireless signals. At the same time, a receiving device needs the potential to capture incoming signals.
Examples of wireless communication technologies include the following:
- Infrared communication, where the sender and receiver exchange a light beam.
- Wi-Fi, which empowers uninterrupted signal transmission in the proximity of a router.
- Radiofrequency, or broadcast radio, which allows data to travel over long distances.
- Bluetooth, a way to connect two devices for data transportation at up to 100 meters.
- Satellite communication, where a satellite gets, amplifies, and sends a signal back to Earth.
- Cellular communication, which offers an opportunity to transfer data over mobile phones.
- Microwave communication, which is about carrying signals directly or through satellites.
