Bluetooth is a blueprint for the employment of low power radio communications to wireless telephones, PCs, and other network wireless devices over short distances. The name Bluetooth is essentially borrowed from Harald Bluetooth, a Denmark king more than one thousand years back. The technology of Bluetooth was basically engineered to support straightforward wireless networking of devices and peripherals, which includes cell telephones, PDAs, and wireless headsets.
The wireless signals that are broadcast by Bluetooth cover short distances of nearly thirty feet, typically communicating less than one MPps ( Mega Byte per second ). The networks of Bluetooth feature dynamic topology called PAN or a piconet. The piconets contain a minumum of 2 and up to 8 peer devices. The devices will communicate using customs that are a part of the blueprint. Although the Bluetooth standard will use the same 2.4 GHz range as 802.11b and 802.11g, the technology isn't acceptable for a Wi-Fi replacement. Compared to Wi-Fi, Bluetooth is much slower, limited in range, and essentially supports less devices.
If you have a cell telephone or other wireless device, you must look into Bluetooth. The technology is just impressive, making it something which will be around for many years to come. As technology gets larger and larger, you should expect Bluetooth to advance also.
