Bluetooth is a specification for the use of lowpower radio communications to wireless phones,computers, and other network wireless devices overshort distances. The name Bluetooth is actuallyborrowed from Harald Bluetooth, a Denmark kingmore than 1,000 years ago.
The technology of Bluetooth was primarily designedto support simple wireless networking of devicesand peripherals, which includes cell phones, PDAs,and wireless headsets. The wireless signals thatare transmitted by Bluetooth cover short distancesof up to 30 feet, generally communicating lessthan 1 MPps (Mega Byte per second).
The networks of Bluetooth feature dynamic topologycalled PAN or a piconet. The piconets contain aminumum of two and a maximum of eight peer devices.The devices will communicate using protocols thatare part of specification.
Even though the Bluetooth standard will utilizethe same 2.4 GHz range as 802.11b and 802.11g,the technology isn't suitable for a Wi-Fireplacement. When compared to Wi-Fi, Bluetoothis much slower, limited in range, and actuallysupports less devices.
For short range devices, Bluetooth is rapidlybecoming the best. The technology is more popularwith cell phones, as Bluetooth headsets are theway to go these days. To use Bluetooth, yourcell phone will need to have it enabled, or aninfared device somewhere on the phone.
Upcoming devices are utilizing Bluetooth as well,such as PS3 and the Nintendo Revolution. Thewireless controllers will be Bluetooth enabled,which will give players the cutting edge.
If you own a cell phone or other wireless device,you should look into Bluetooth. The technologyis nothing short of spectacular, making itsomething that will be around for years andyears to come. As technology gets bigger andbigger, you can expect Bluetooth to advanceas well.
