1. What is Piconet? -
A collection of devices connected through Bluetooth technology in an ad hoc fashion.
2. What are the three main types of connection used by Bluetooth? -
Single slave, Master slave, Scatternet .
3. 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.
4. Which method is primarily used for Voice transfer? -
Synchronous Connection Oriented (SCO) is a method primarily used for Voice transfer.
5. Which Bluetooth version uses adaptive frequency hopping? Why? -
In Version 1.2 Adaptive frequency hopping method is used, which improves resistance to radio interference, and provides higher transmission speed.
6. How many SCO links are there in a piconet? -
In a piconet, there can be up to three SCO links of 64,000 bits per second each.
7. what is the total number of masters and slaves in a piconet? -
1 Master and 7 Slaves.
8. Which method is used for Data transfer? -
Asynchronous Connectionless (ACL) is Data transfer method in Bluetooth

What is Bluetooth ? Why is Bluetooth used?
Bluetooth
Bluetooth is a type of wireless protocol that utilizes a communications technology that is short range. Bluetooth facilitates the transmission of data over short distances from mobile devices, especially mobile phones. This creates wireless area networks sometimes referred to as PANs (Personal Area Networks).
Therein lies an important intention that led to the development of Bluetooth, the creation of a wireless protocol that would ultimately be able to connect multiple wireless devices and thus overcome the shortcomings that did arise from the synchronization of wireless devices.
Bluetooth makes good use of a modern radio technology known as frequency hopping over spread spectrum. It transmits chunks of data that is being sent in a chopped up form on up to more than 75 distinct frequencies. In the most basic form, Bluetooth and its modulation is a shift keying mode of Gaussian Frequency which is made in a way that it could even reach a 1 Mb/s gross rate in terms of data processing.
Bluetooth offers a perfect way of information exchange and connection over such devices as mobile phones, laptops, printers, telephones, digital cameras, GPS receivers, video game consoles and personal computers. This is done over a short range bandwidth (2.4 GHz) via radio frequency, which is globally unlicensed.
Bluetooth has its specifications packaged, developed and harmonised amidst being licensed by Interest Groups in the line of its operation. These Interest groups consist of various companies in the business of computing, telecommunication, networking and even consumer electronics.
