Introduction to Bluetooth Networking Technical Seminar Topic:
It is a small private area network especially used for short places. It low power consumption connectivity they are used by devices like mobiles, desktops, laptops, printers, keyboards mouse etc.
This technology is based on the ad hoc network. Bluetooth was first used by mobile company Sony Ericson, after that many companies like Nokia, IBM, Toshiba etc. come together to form a group and they names the group as Bluetooth. They use the radio communication frequency which is freely available in our country.
This technique operates in 2.4 GHz band which is available worldwide. It has 79 channels and it can support up to 8 devices in a piconet. There are many wireless networks available in the market like IEEE 802.11(Wi-Fi), IrDA, GSM, GPRS etc. but Bluetooth is very popular among then as it is very cheap and easy to use.
Bluetooth gives the speed up to 1 MB/sec and It has the range of 10 meters. It connects through IP and Cellular network via PPP.
IEEE 802.11: they are used for LANs to extend the 802.3. it has the speed up to 11 MB/sec.
IrDA: they are low cost infrared data interconnection standards. User must in the range of 1 meter. It is also bi communicational network. It gives the speed up to 4 MB/sec.
A Bluetooth system consists of group of computers connected to each other to form a network called piconet. In piconet it has one master device and other is 7 active slave devices. But all the devices must be in the range of 10 meters. We can also connect two piconets.
Problems:
Blue snarfing: – user can copy the address information from other Bluetooth user phone.
Blue spamming: – we can also send spam to other users.
Blue jacking: – we can also send the message to other Bluetooth phone.
