Wireless and Mobile Multimedia Technology

Wireless and Mobile Multimedia Technology Bluetooth: Bluetooth is a short-range radio link intended to replace the calble(s) connecting portable and/or fixed electronic devices. Key features are robustness, low complexity, low power and low cost [1]. There are already similar standards in this market, such as IrDA, HomeRF and IEEE 802.11 family. Bluetooth is designed to offer some unique advantages that none of the others can provide. However, as a result of the lower data rate and transmission range, Bluetooth offers much lower cost per node (approximately 5 ~ 10% of HomeRF and IEEE 802.11). So it is more suitable for applications involving low data rate (data and voice), small number of devices (8 at maximum), low power consumption and short range (up to 10 meter), such as PC-to-peripheral networking, home networking, hidden computing, data synchronization (such as between PC and PDA), mobile phone devices, and future smart devices or entertainment equipment. Bluetooth is a new system that connect electronic devices via wireless radio technology .this means that hands free device can now communicate directly with the phone without having wires plugged in. The range of Bluetooth is up to 10m-so when you get in the car ,you can leave your mobile in your pocket or handbag and be instantly hands free! Why is called Bluetooth? Harald Bluetooth was the king of Denmark during the late 900s .Harald united Denmark and part of Norway into a single kingdom and also introduce Christianity into Denmark. He also left a large monument ,the Jelling rune stone ,in memory of his parents. In 986 during a battle with his son,Svend Forkbeard,Harald was killed. The name Bluetooth was chosen to indicate the importance the part companies from the Baltic region .have played in the communication industry, although it gives no indication of how the system and technology operates .
