The Zoom Model 4322 Zoom Bluetooth Adapter plugs into a personal computer to provide a wireless connection to another Bluetooth-enabled device, such as an audio system receiver, modem, mobile phone, headset, computer, PDA, mouse, keyboard, or peripheral. The Model 4322 is a Class 2 Bluetooth device, which provides a range of up to 10 meters*. The Model 4322 will communicate with all other Bluetooth devices, including Class 1, Class 2, & Class 3 devices. When connecting to Class 3 devices, the Model 4322 is limited to the shorter range of the less powerful Bluetooth device. The Model 4322 is Bluetooth version 2.1+EDR compliant, which increases speed, reduces battery consumption, improves security, provides faster pairing & allows superior performance in the presence of interference from 802.11 wireless devices & other 2.4 G Hz radios. The Model 4322 supports throughput of up to 2.1 megabits per second (3 Mbps nominal), the maximum allowed by the Bluetooth version 2.1 + EDR standard. The Model 4322 USB (Universal Serial Bus) adapter is compatible with Macintosh & Windows computers. The small “thumbnail” size of the Model 4322 allows it to remain in the USB (Universal Serial Bus) port of a computer, secure from impact. Other adapters protrude significantly from the USB (Universal Serial Bus) port, & a blow to the adapter can easily damage the USB (Universal Serial Bus) port. Please note: networking components such as switches, routers, UPS & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
