BLUETOOTH???

Bluetooth is an open wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, Global Positioning System (GPS) receivers, digital cameras, and video game consoles through a secure, globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency bandwidth. Otherwise, Bluetooth is a standard and a communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 1 meter, 10 meters, 100 meters) based on low-cost transceiver microchips in each device. Bluetooth makes it possible for these devices to communicate with each other when they are in range. Because the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other. There are some Bluetooth applications:-


• Wireless control of and communication between a mobile phone and a hands-free headset. This was one of the earliest applications to become popular.

• Wireless networking between PCs in a confined space and where little bandwidth is required.

• Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer.

• Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX.

• Replacement of traditional wired serial communications in test equipment, GPS receivers, medical equipment, bar code scanners, and traffic control devices.

• For controls where infrared was traditionally used.

• For low bandwidth applications where higher [USB] bandwidth is not required and cable-free connection desired.

• Dial-up internet access on personal computers or PDAs using a data-capable mobile phone as a modem.



Everybody like to bluetooth2 right?? Lalala~
