The Model 4322 Bluetooth adapter plugs into the USB port of a computer. The Model 4322 provides the computing device with a Bluetooth wireless connection to another Bluetooth enabled device, such as modem, mobile phone, headset, another computer, or a peripheral. The small "thumbnail" size of the model 4322 allows it to remain in the USB port of a computer, secure from impact. Other adapters protrude significantly from the USB port, and a blow to the adapter can easily damage the USB port. The Model 4322 is Bluetooth version 2.1 + EDR (Enhanced Data Rate) compliant to provide speeds up to 3Mbps, reduce battery consumption, and provide superior performance in the presence of interference from other 2.4 GHz radios. The Model 4322 is a Class 2 Bluetooth radio with a range of up to 10 meters (32 feet). The Model 4322 is interoperable with Class 1, 2, and 3 Bluetooth devices. The Model 4322 includes support for newer Bluetooth profiles designed to communicate higher quality audio in stereo and better video. Those profiles include Basic Imaging Profile (BIP), and Generic Audio Video Distribution (GAVDP). The Model 4322 can maintain both A2DP/AVRCP (audio) profiles and an HSP (headset) profile concurrently when connecting to a headset. This allows toggling between music and telephony applications.
