Bluetooth…. An excellent gift of
technology!Previously, it was very difficult to access many thing, download, upload and
many more seems to be a tough job. But after the arrival of this new
technology work becomes easy! Many job has been reduced, time saved along with energy. Bluetooth has made the job more easy and fast. Let me explain what actually Bluetooth is! Bluetooth is a device most commonly used with cell phones and handheld computing devices, either using a Bluetooth headset or transferring files from phones/PDAs to computers.Bluetooth is an industrial specification for
wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles via a secure, globally unlicensed short-range radio frequency. Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device. Bluetooth is in a variety of new products such as phones, printers, modems, and headsets, to name a few. Bluetooth is acceptable for situations when two or more devices are in close proximity with each other and don't require high bandwidth. Bluetooth is most commonly used with cell phones and handheld computing devices, either using a Bluetooth headset or transferring files from phones/PDAs to computers. Since Bluetooth uses short-range radio frequencies, it is not as effective for setting up networks that can be accessed from remote locations as with Wi-Fi.Bluetooth applications:Wireless control of and communication between a cell phone and a hands free headset or car kit. This is the most popular use. Wireless networking between PCs in a confined space and where little bandwidth is required. Wireless communications with PC input and output devices, the most common being the mouse, keyboard and printer. Transfer of files between devices via OBEX. Transfer of contact details, calendar appointments, and reminders between devices via OBEX. Replacement of traditional wired serial communications in test equipment, GPS receivers and medical equipment. For remote controls where infrared was traditionally used. Sending small advertisements from Bluetooth enabled advertising hoardings to other, discoverable, Bluetooth devices. Wireless control of a games console, Nintendo's Wii and Sony's PlayStation 3 will both use Bluetooth technology for their wireless controllers. Sending commands and software to the LEGO Mindstorms NXT instead of infrared.
