This means cellular phones, PDAs, and mobile computers can transfer data without cables. Instead of the static configurations of traditional networks, Bluetooth personal networks can be set to assemble themselves. A user could instruct them to grow, shrink and even disappear, as people with Bluetooth devices move within range and then out again. With the Bluetooth wireless technology, connecting and communicating between devices could occur automatically, requiring no interaction or intervention from the device's owners. Moreover, Bluetooth connections are designed with security in mind, incorporating encryption, authentication, frequency hopping, and low power radio control.
Applications can also add higher levels of security to devices.
Bluetooth wireless technology operates in the same 2.45GHz frequency band worldwide. Thus your Bluetooth device will function whether you're in the United States, Asian, Europe, Latin America, or anywhere else on the globe. What's more, a single device may have multiple simultaneous wireless connections. The Bluetooth SIG developed the specification for the Bluetooth wireless technology. The organization supports Bluetooth development across a wide range of industries including semiconductor design and manufacturing, telecommunications, consumer products, networking, and automotive.
