Wireless communication passes information between two or more points that are not connected by an electrical conductor.
Keyboard is the one which operates with both wired and wireless connection. Most of the users were using wireless keyboard to access information from Laptop or PC. The wireless keyboards works with the help of radio frequency, infrared or Bluetooth technology.
Best wireless keyboard
Wireless keyboard passes certain type of information by using infrared technologies i.e., light waves transmit signal to other infrared-enabled devices. These waves are too long and we can’t view with a naked eye. Sometimes, you might observe un-proper working of the keyboard, the main reason includes – if an object passes between computer and keyboard then these waves will be disturbed.
Wireless keyboard communicates by using radio frequency signals with a range from 27MHz to 2.4 GHz. Current days, most of the wireless keyboards use 2.4 GHz radio frequency.
The wireless keyboard can be connected using RF technology with the help of two parts i.e., a transmitter and a receiver. The radio transmitter is inside the wireless keyboard where as the receiver will be plugged into a keyboard port or USB port. Computer will recognize the keyboard once both the receiver and transmitter have been plugged in.
