Bluetooth Technology FAQ

[Alan1984]

[/url]Q: Will Bluetooth and Wireless LAN (WLAN) interfere with each other?
A: No, both Bluetooth and WLAN can co-exist. 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.
[/url]Q: 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. This bandwidth is capable of transmitting voice, data, video and still images.
[/url]Q: Is Bluetooth practical for use with mobile devices?
A: Yes. One concern for mobile computing users is power consumption. Bluetooth radios are very low power, drawing as little as 0.3mA in standby mode and 30mA during sustained data transmissions. Bluetooth radios alternate among power-saving modes in which device activity is lowered to maximize the mobile power supply.
[/url]Q: What is a Personal Area Network (PAN)?
A: A Personal Area Network is another name for a Bluetooth Piconet.
[/url]Q: What is HomeRF ?
A: HomeRFlike Bluetooth is a specification for connectivity and mobility in a home-like environment. HomeRF Working Group has developed a specification for wireless communications in the home called the Shared Wireless Access Protocol (SWAP).
