Kleer - Computer Definition
Wireless music transmission in the unlicensed 2.4 GHz band. Requiring the Kleer technology in both sending and receiving devices, full 1.411 Mbits/sec CD-quality sound can be sent to headphones and speakers using substantially less power than Bluetooth or Wi-Fi. While Bluetooth and Wi-Fi need at least 20 MHz of bandwidth for music, Kleer uses narrowband 3 MHz channels, which are easier to find in a crowded 2.4 GHz environment. In addition, Kleer can transmit to multiple receivers simultaneously. See aptX.
