Wireless technology has been around for over a hundred years. The invention of this technology was the combination of efforts by several famous scientists, each contributing toward specific areas of electromagnetism and electromagnetic fields. From their contributions came about the inventions of the radio and television. The main concept of wireless is to transmit a signal, data, or other information through the air using electromagnetic waves.
One of the biggest steps toward developing wireless technologies is attributed to James Maxwell, a Scottish physicist, who first theorized the relation between magnetism, electricity, and electromagnetic fields. In fact, these theories are still used today with modern wireless technologies, while they do work slightly differently.
Infrared Technology
Infrared was one of the first wireless technologies developed. It uses infrared beams to transmit information short distances and is very limited. This technology works well in remotes used for TVs, DVD players, stereo systems, garage door openers, and more.
Wi-Fi Technology
This type of wireless technology is able to transmit data at fast speeds in homes and businesses, and even in public areas. As such, it has become the preferred method for accessing the Internet by many people.
Bluetooth Technology
Bluetooth is a wireless technology that works over short distances and allows people the ability to control what types of devices are connected with each other. It does transmit data at fast speeds as found in smartphone, computers, TVs, universal remote controls, video gaming consoles, and other such devices.
4G Technology
4G is the latest wireless technology used with cellular enabled devices. This wireless technology works similarly to how radio and TV signals are transmitted. While the technology has improved, and is reliable for texting and talking, it can still be slower than other wireless technologies when accessing the Internet.
As you can see, our lives have gotten easier, thanks to wireless technologies and remote controls. For universal and remote controls for your electronic devices, call Replacement Remotes now at 1-855-5-REMOTE (1-855-573-6683).
