Bluetooth is a way to achieve wireless communication basically for Adhoc Networks using FHSS (Frequency Hopping Spread Spectrum). In Bluetooth piconet there can be 8 nodes active at a point of time (1 master and 7 slaves) and can have maximum of 255 nodes as parked one. Two or more piconet when communicate form a scatter net. Development of Bluetooth started with merely connecting peripheral without wires, by some well-known companies like Ericsson, Intel, Nokia etc. Bluetooth has now become a major short range, low power communication technique. There are other wireless communication techniques, viz. IEEE 802.11, Infrared etc. But still Bluetooth is gaining the popularity. Main reasons for that is low range, short power, low cost hardware and many more. Bluetooth uses 2.4 GHz radio frequencies, which is mostly free in different countries. Bluetooth is very popular type of wireless communication but it also has some drawbacks like bluejacking, bluesnarfing, low data rate, Interference etc
