4310BF Bluetooth USB Adapter, 100 m, 3 Mbps The Zoom Bluetooth Adapters plug into a personal computer to provide a wireless connection to another Bluetooth-enabled device, such as an audio system receiver, a modem, mobile phone, headset, computer, PDA or peripheral. Zoom 4310BF Bluetooth adapter is Class 1 Bluetooth device, which allows them to provide a range of up to 100 meters (330 feet), the longest range provided under the Bluetooth standard. Zoom's Class 1 Bluetooth device will communicate with all other Bluetooth devices, including Class 1, Class 2 and Class 3 devices. When connecting to Class 2 and Class 3 devices, Zoom Bluetooth adapters are limited to the shorter range of the less powerful Bluetooth devices on the other end of the transmission. Both units are Bluetooth version 2.0 + EDR compliant, which increases speed, reduces battery consumption and allows superior performance in the presence of interference from 802.11 wirelesss devices and other 2.4GHz radios. Both units support throughput of up to 3 megabits per second, the maximum allowed by the Bluetooth version 2.0 + EDR standard.
All Zoom Bluetooth adapters come complete with a software installation wizard which makes setup of the Bluetooth protocol stack fast and easy.
The Bluetooth Piconet protocol supports concurrent connections with up to seven other Bluetooth devices. Security is ensured with the implementation of a Bluetooth security key and data encryption. Each Zoom Bluetooth adapter contains a unique link key that prevents unauthorized access to the attached computer. The key is transmitted in a secure environment to prevent interception. Unlike an 802.11 b/g wireless device, Bluetooth wireless links are not susceptible to eavesdropping and false authentication.
