A wireless keyboard is a computer keyboard that allows the user to communicate with computers, tablets, or laptops with the help of radiofrequency (RF), infrared (IR) or Bluetooth technology. It is common for wireless keyboards available these days to be accompanied by a wireless mouse.
Wireless keyboards based on infrared technology use light waves to transmit signals to other infrared-enabled devices. But, in the case of radiofrequency technology, a wireless keyboard communicates using signals which range from 27 MHz to up to 2.4 GHz. Most wireless keyboards today work on 2.4 GHz radiofrequency. Bluetooth is another technology that is being widely used by wireless keyboards. These devices connect and communicate with their parent device via the Bluetooth protocol.
A wireless keyboard can be connected using RF technology with the help of two parts, a transmitter, and a receiver. The radio transmitter is inside the wireless keyboard. The radio receiver plugs into a keyboard port or USB port. Once the receiver and transmitter are plugged in, the computer recognizes the keyboard and mouse as if they were connected via a cable.
The main advantage of using a wireless keyboard rather than a regular keyboard is that it offers much more mobility. A wireless keyboard can be used on a lap, in a bed, or just used while on-the-go for laptop users. All wireless keyboards use either radio waves or infrared to communicate with the wireless adapter that usually comes with the keyboard. The keyboards that use radio waves have much more flexibility as they do not need to "see" the wireless adapter. Wireless keyboards that use infrared, however, need to be in a direct viewing range of the wireless adapter – much like a TV remote.
Another thing to consider before purchasing a wireless keyboard is that it operates on battery power rather than using electricity from the user's computer. Most wireless keyboards use four AA lithium batteries so the user does not have to worry about finding special batteries but they will need to be replaced regularly. Some models of wireless keyboards have a longer battery life than others with the average generally being between six and fifteen months. While this sounds great, the user will need to make sure that they always have spare batteries or a regular keyboard nearby so that their wireless keyboard does not spontaneously stop working.
