Bluetooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Bluetooth" is borrowed from Harald Bluetooth, who was a king in Denmark more than 1,000 years ago.
Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including mice, keyboards, and cell phones. The wireless signals transmitted in Bluetooth reach over short distances, typically up to 30 feet (10 meters). Bluetooth devices generally communicate at less than 1 Mbps. With a lack of USB ports, most tablets utilize a Bluetooth connection to pair with peripheral devices, such as the K4000 keyboard. Bluetooth mice such as the X4000b can also be beneficial when there are a lack of free USB ports.
