what is blue tooth?

Answer 1

bluetooth enables short-range wireless connections between desktop and laptop computers and a range of peripherals ;)

Answer 2

Bluetooth for mobiles is a way to transport pictures, sounds etc. from a mobile to another without paying. But the phones have to be close to each other.
Blue tooth generally is a tooth painted in the colour of blue.(just kidding).

Answer 3

Bluetooth networking transmits data via low-power radio waves. It communicates on a frequency of 2.45 gigahertz (actually between 2.402 GHz and 2.480 GHz, to be exact). This frequency band has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM). Bluetooth can connect up to eight devices simultaneously. With all of those devices in the same 10-meter (32-foot) radius, you might think they'd interfere with one another, but it's unlikely. Bluetooth uses a technique called spread-spectrum frequency hopping that makes it rare for more than one device to be transmitting on the same frequency at the same time. In this technique, a device will use 79 individual, randomly chosen frequencies within a designated range, changing from one to another on a regular basis. In the case of Bluetooth, the transmitters change frequencies 1,600 times every second, meaning that more devices can make full use of a limited slice of the radio spectrum. Since every Bluetooth transmitter uses spread-spectrum transmitting automatically, it’s unlikely that two transmitters will be on the same frequency at the same time. This same technique minimizes the risk that portable phones or baby monitors will disrupt Bluetooth devices, since any interference on a particular frequency will last only a tiny fraction of a second.

Answer 4

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 lets these devices communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, so long as the received transmission is powerful enough.

I use Verizon wireless for my cell phone and have a Bluetooth earpiece that I use to make hands free calls when driving or even walking..

Wireless control of and communication between a cell phone and a hands free headset or car kit. This is the most popular use.

Answer 5

What is Bluetooth wireless technology?

Bluetooth technology is how mobile phones, computers, and personal digital assistants (PDAs), not to mention a broad selection of other devices, can be easily interconnected using a short-range wireless connection. Using this technology, users can have all mobile and fixed computer devices be totally coordinated.

Answer 6

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

Answer 7

Bluetooth is a specification for short-range radio links between mobile computers, mobile phones, digital cameras, and other portable devices. The devices using this specification need not be in line-of-sight and can communicate upto a range of 20 feet.
