WiFi (Audio distortion and drop-outs and slower data)īluetooth (Audio distortion and drop-outs) The information available suggests that Bluetooth security will be adequate for most purposes but users with higher security requirements will need to employ stronger algorithms to ensure the security of their data. Key generation and authentication seems to be using the 8-round SAFER+ encryption algorithm. This arrangement allows Bluetooth to be used in countries with regulations limiting encryption strength, and “facilitate a future upgrade path for the security without the need for a costly redesign of the algorithms and encryption hardware” according to the Bluetooth specification. The sum of the width of the LFSRs is 128, and the spec says “the effective key length is selectable between 8 and 128 bits”. The Bluetooth specification 1.0 describes the link encryption algorithm as a stream cipher using 4 LFSR (linear feedback shift registers). What kind of encryption will be used for Plantronics Bluetooth security? A. It also includes device authentication, user authorization, and voice encryption. The headset and adapter communicate via the standard 2.4 GHz Bluetooth link, which provides high-quality digital audio, range up to 30 feet and advanced encryption for secure communication. How secure are Plantronics Bluetooth transmissions? A. Plantronics’ Bluetooth headsets are currently Class 2 Bluetooth devices with a range of approximately 10 meters, or roughly 30 feet. What is the range of Bluetooth transmitter/receivers? A. Heavy use of WiFi (i.e: VoIP via WiFi) will further decrease the BT deployment density. WiFi will decrease the number of BT devices that can be successfully deployed. Keep every source of interference (including other Bluetooth devices) separated by at least 7ft from any of the paired BT devices. Keep every paired BT devices separated by no more than 7ft. The 7ft rule will assure you successful operation and acceptable audio quality of multiple Bluetooth device. What is the practical distance for Bluetooth headsets? A. the FAA is the governing body to grant approval for Bluetooth product use on aircraft therefore, we must defer to their impending ruling. The Federal Aviation Administration (FAA) and other aviation regulatory bodies worldwide are currently reviewing the use of Bluetooth products on private and commercial aircraft. Can Bluetooth products be used on a commercial airline? A. The Bluetooth Logo Certification Program requires Bluetooth products to interoperate with products manufactured by other vendors those products that don’t interoperate will not be allowed to use the Bluetooth logo. Are different brands of Bluetooth products compatible with each other? A. Since Bluetooth devices use Frequency Hopping and most WLANs use Direct Sequence Spreading techniques they each appear as background noise to the other and should not cause any perceivable performance issues. No, both Bluetooth and WLAN can co-exist. Will Bluetooth and Wireless LAN (Wi-Fi) interfere with each other? A. This bandwidth is capable of transmitting voice, data, video and still images. What is the data throughput speed of a Bluetooth connection? A.Bluetooth transfers data at a rate of 721 Kbps, which is from three to eight times the average speed of parallel and serial ports, respectively. Bluetooth devices use AFH (adaptive frequency hopping) to hop among 79 frequencies at 1 MHz intervals to give a high degree of interference immunity. How many channels does a Plantronics Bluetooth headset use? A. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone. Typical uses include automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting cables. Bluetooth can be thought of as a cable replacement technology. Bluetooth can be used to wirelessly synchronize and transfer data among devices.
