HISTORY OF <ul><li>Bluetooth was originally developed by mobile phone company Ericsson in 1994. Looking for a unique name for the technology, they settled on "Bluetooth" after a tenth century Viking king called Harald "Bluetooth" Blatand. During his reign, he united Denmark and Norway, and was well known for his ability to help people communicate. Presumably, Ericsson's hope was that Bluetooth technology could do the same. </li></ul>
DEFINATION <ul><li>Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment together with little or no work by the user. </li></ul><ul><li>The effective range of Bluetooth devices is 32 feet (10 meters). Bluetooth transfers data at the rate of 1 Mbps. It is also known as the IEEE 802.15 standards </li></ul>
Bluetooth Wireless Technology Profiles <ul><li>In order to use Bluetooth wireless technology, a device must be able to interpret certain Bluetooth profiles. The profiles define the possible applications. Bluetooth profiles are general behaviors through which Bluetooth enabled devices communicate with other devices. Bluetooth technology defines a wide range of profiles that describe many different types of use cases. </li></ul>
PASSCODE <ul><li>In order to 'pair' one Bluetooth device to another, a passcode has to be exchanged between the two devices. When you first connect, one machine will ask you to enter a passcode... enter any 4 digit number. The other device will then ask you for a passcode. Enter the same 4 digit number. It doesn't matter what the passcode is, as long as you enter the same number at both ends. </li></ul>
PHONE TO PC <ul><li>If you have a Bluetooth-enabled mobile phone, then you can use Bluetooth to beam your photos and other objects from your phone to a PC or laptop. You'll need to have Bluetooth on your PC (if it doesn't already have Bluetooth, see our other FAQ on this). With Bluetooth switched on on both the phone and PC, you need to 'pair' the two machines, and then you can use the software on the phone and PC to transfer files. </li></ul>
Different Types Of Bluetooth Adaptor <ul><li>Bluetooth adaptor is used to establish Bluetooth connectivity across very short-range radio frequency bandwidth, making it a refinement of radio broadcasting. </li></ul><ul><li>Bluetooth Printer Adaptors </li></ul><ul><li>This type of Bluetooth adaptor makes printer sharing exceptionally convenient by removing the need for any special configurations or wires on a typical network. </li></ul><ul><li>USB Bluetooth Adaptors </li></ul><ul><li>It is a type of Bluetooth adaptor used by desktop or laptop systems that do not have an adaptor built in the system. </li></ul><ul><li>BMW Bluetooth Adaptor </li></ul><ul><li>A new type of Bluetooth adaptor that has been designed to help drivers in safety and conveniently use hands-free mobile phone while driving. </li></ul>

Security <ul><li>When not using Bluetooth, turn it off. </li></ul><ul><li>Set your Bluetooth mode so that it isn't discoverable. </li></ul><ul><li>Be careful of devices that may have a guessable passcode. </li></ul><ul><li>Be careful when setting a device to "trusted" or "authorized", as that device can then access all of your devices services, features, and potentially - data. </li></ul>
Are WiFi and Bluetooth compatible? <ul><li>Bluetooth and WiFi are both radio technologies, but they differ in the frequencies and protocols that they use. They don't interfere with each other, but the two don't talk to each other either - in other words you can't get a device with Bluetooth to communicate to a device that only supports WiFi </li></ul>
ADVANTAGES <ul><li>Cable-free, so less messy leads to worry about </li></ul><ul><li>Interoperability - In most cases, you can use your portable Bluetooth device to connect with other existing Bluetooth points, without having to carry a data lead and CD of drivers around with you </li></ul>
Capabilities that Bluetooth can Provide To User <ul><li>Make calls from a wireless headset connected remotely to a cell phone. </li></ul><ul><li>Eliminate cables linking computers to printers, keyboards, and the mouse. </li></ul><ul><li>Hook up MP3 players wirelessly to other machines to download music. </li></ul><ul><li>Set up home networks so that a couch potato can remotely monitor air conditioning, the oven, and children's Internet surfing. </li></ul><ul><li>Call home from a remote location to turn appliances on and off, set the alarm, and monitor activity. </li></ul>
