Wireless Keyboard : What is it?
Wireless keyboards connect to the computer using radio signals, infrared beams, or Bluetooth instead of traditional cables. They allow users to work away from the computer screen within the keyboard’s specified range. They are ideal for applications requiring remote operation and large working areas, such as presentations and home cinemas. Most wireless keyboards are battery-operated and may have built-in mice for added functionality.
Kinds of Wireless Keyboards include the following:
|RF wireless keyboards|
- Radio frequency (RF) keyboards send radio signals to a receiver connected to the computer’s USB or PS/2 port.
- They can be used at any angle within the receiver’s range, such as the floor or a separate desk.
- They are prone to interference from other radio devices.
Infrared wireless keyboards
- Infrared wireless keyboards use a constant infrared beam to connect to the computer.
- They require a direct line of sight connection and can only be used at specific angles.
- They have slower response times and can be interrupted by physical barriers.
Bluetooth wireless keyboards
- Bluetooth wireless keyboards can be used up to 10 meters from the keyboard within a 360-degree radius.
- They have a more consistent connection, faster response, and less interference than RF and infrared keyboards.
- They can also be used with other Bluetooth devices, such as wireless phones and headsets.
|Power: Choose a wireless keyboard with a timed low-power mode that lowers or shuts off the connection when you leave the computer. Avoid keyboards with backlit keys because they use up additional battery power. If you need backlit keys for visibility, look for lights that automatically turn off in bright areas.|
Connection quality: Choose a wireless keyboard that maintains a fast, uninterrupted connection with the computer. Look for one with a wide distance range so that you can move away from the monitor when needed.
