Bluetooth signals do not interfere with our PCs or cordless phones or portables. Why?
– Bluetooth uses low-power signals, it plays around in 2.45 GHz range, while most of consumer devices would be using 900 MHz. • What is Airport? – Airport is a wireless communications system, like Bluetooth. It is based on the IEEE 802.11 recommendation. It also uses 2.4 GHz frequency band, but its range is about 45 meters and it boasts a transmission speed of 11 Mbit/second. It is developed by Lucent Technologies. • What is Piconet? – A collection of devices connected through Bluetooth technology in an ad hoc fashion. • What are the three main types of connection used by Bluetooth? – Single slave, Master slave, Scatternet . • What is FEC in Bluetooth? – Forward Error Correction is a method by which Bluetooth increases its noise immunity. FEC is a method that enables a receiver to not only detect, but also correct errors in a transmission. • Which method is primarily used for Voice transfer? – Synchronous Connection Oriented (SCO) is a method primarily used for Voice transfer. • What i
