Different Kinds of Wireless

Wireless technology allows people to communicate without using wires or cables. With wireless technologies, you can communicate with people over very long distances. This technology includes Infrared Radiation (IR), Radio Frequency (RF) waves, and Bluetooth technology. 

Bluetooth: It is a short-range wireless or radio technology, which aims to simplify communications among devices and the internet. Bluetooth technology also works to simplify data synchronization between computers and other internet-connected devices. Today, this technology is found in millions of products such as smartphones, laptops, headsets, and portable speakers. 

Radio Frequency: It refers to electromagnetic radio waves and their rate of oscillation in the range of 3 kHz to 300 GHz. Radiofrequency also focuses on the alternating currents that carry the radio signals. In addition, it is used for transmission, communications, and broadcasting.  

Infrared: it is a short-range wireless technology used in mobile device communication. This type of wireless technology has limitations since it requires line-of-sight. Thus, it has a short transmission range and can’t penetrate the walls. Infrared transceivers are quite affordable, which serve as short-range transmission or communication solutions.
