The term wireless is used to describe telecommunications in which electromagnetic waves carry the signal over part or all the communication path i.e., there’s no need for any cable. In wireless transmission, the medium used is the air through not only electromagnetic signals but also radio and microwave signals.
Wireless technology started with radio telegraphy using Morse code. When the process of modulation was introduced, it became possible to transmit voices, music and other sounds wirelessly, becoming one of the most important ways of transmission of information from one device to other devices.
Wireless could also refer to any device that communicates with other devices wirelessly, meaning there is no physical connection between them, which facilitates the communication between people, devices, like smartphones, computers or Bluetooth technology printers and other technologies as well. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing are also sometimes classified as wireless.
Nowadays, wireless communication technology refers to a variety of wireless communication devices and technologies from smartphones to computers, tabs, laptops, Bluetooth technology printers.
Advantages of Wireless Network
Wireless and mobile networks technologies such as WI-FI, WIMAX, RF, LTE, 4G, are an efficient way to bring broadband not only to mobile devices but also to remote regions.
One of the benefits and the most obvious one of wireless is that the wires stopped to be a problem since you don’t need to worry about plugging and unplugging wires or about getting tangled up.
Another advantage is that with Wireless technologies it became possible to work from everywhere since wireless networks are cheap and easy to set up. At a location, you can access the internet from multiple devices that support Wi-Fi just by just having a router at home or at the office, instead of having to setup a LAN. This universal access permitted local services, like restaurants, malls, hotels to offer internet via Wi-Fi to their customers.
