Wireless Audio Whitepapers

The following whitepapers are available for you to download.

Kleer Advantages Over Bluetooth

This whitepaper compares Kleer technology to Bluetooth technology for the application of wireless streaming audio. Kleer’s technology is optimized for high quality wireless audio transmission between portable audio devices. Kleer’s patented sub-sampling radio architecture combines lossless audio transmission, low-power consumption, low latency, and best-in-class ISM band co-existence to provide far superior audio quality with up to 10 times the battery life of a comparable Bluetooth solution.

ISM Band Coexistence

This whitepaper discusses ISM band coexistence issues for wireless audio applications, and some of the factors that should be considered in selecting a wireless audio technology.
The Industrial, Scientific, and Medical (ISM) radio bands were created as a place to relegate equipment that produces a lot of radio interference that could disrupt other radio applications that are sensitive to such noise. The license-free nature of these bands has made them attractive for use by various commercial applications/communication protocols such as Wireless Local Area Network (WLAN), Bluetooth (BT), cordless telephones, baby monitors, wireless security systems, etc. Consequently, these protocols are subject to interference from noisy equipment such as microwaves as well as from other intelligent applications competing for the same space.
