Bluetooth is a short range radio technology that is used in mobile telephones and other handheld devices. The range is typically 30 meters but depends on the environment it is being used in.\n\nBluetooth is typically used to transfer business cards, data, sound files, pictures and other files between mobile devices.\n\nFor example, you may have a ring tone or a picture that you took with your camera phone and you want to let your friend have a copy of that file.\n\nYou can transfer these types of files using bluetooth.\n\n\nTypically you would 'search for bluetooth devices'. Your mobile device will scan for other bluetooth devices and list any that are found.\n\nYou can then initiate a connection with any of these bluetooth devices, although a pin code may need to be entered to complete the connection.\n\nYou can transfer files between a mobile device and a home computer or laptop by using a gadget called a bluetooth dongle.\n\nA bluetooth dongle plugs into the USB port of your computer or laptop and allows it to send and receive using bluetooth.

Bluetooth is a radio standard primarily designed for low power consumption, with a short range.  It is for personal devices like:  peripherals such as printers, mice and keyboards; headsets for mobile phones and smartphones; etc.\n\nWi-Fi was intended to be used for mobile devices and LANs, but is now often used for Internet access.  It enables a person with a wireless-enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point. The geographical region covered by one or several access points is called a hotspot.  \n\nHope this helps!

Technology Reaches “Brave New World” Proportions—The Human Body as Broadband Connection\n\nA new technology developed by a Japanese communications company called Nippon Telegraph and Telephone Corporation (“NTT”) uses the human body for broadband networking. More specifically, NTT’s RedTacton technology sends data over the surface of the skin at speeds equivalent to a fast broadband data connection.\n\nOther companies, most notably, IBM and Microsoft, have done work in this field, but NTT is the first company to figure out how to transfer data over the skin without attaching transmitters to the human body. Instead, the transmitters can be built into devices such as an MP3 player or a cell phone and are effective within 20 centimeters of the human body. Using the RedTacton transceiver, data can be transmitted by touching, holding, sitting, walking, or stepping on a particular spot. Data can even travel through clothing and shoes.\n\nThe way the RedTacton technology works is by coupling a transmitter with weak electric fields on the surface of the body. These electric fields pass through the body to a RedTacton receiver, where they come into contact with an electro-optic crystal. A sensor then bounces a laser beam off the crystal and measures the reflected beam. The polarization of the reflected light is affected by oscillations in the electric fields surrounding the crystal; therefore, the electric fields that pass over the body influence the characteristics of the reflected beam. The reflected light is then\n  converted back into electric signals to receive the transmitted data. Sound like magic? The NTT technology is based on a technique called electric field photonics.\n\nIn terms of safety, according to NTT, the RedTacton transceiver electrodes are covered with an insulating film that prevents current from the transceiver from flowing into the user’s body upon contact. The company notes, however, that the RedTacton technology does create in the body the same level of weak induction current as cell phones.\n\nNTT has several Japanese patents covering its technology and is “patent pending” in foreign countries. NTT’s technology is an improvement over previous technologies developed by Microsoft and IBM. In the mid-1990s, IBM developed the first personal area network (“PAN”). This PAN allowed two people to transmit business card information to each other electronically via a handshake. In June of 2004, Microsoft obtained a patent on a “method and apparatus for transmitting power and data using the human body.” Microsoft’s patent, however, required a pair of electrodes to be attached to the body.\n\nWhy all this interest in PANs? Some feel these types of communications are more secure; others feel they have potential application in the medical device arena. Technology has already been developed that allows humans to communicate with computers using their thoughts only. What is clear is that we have entered a new world where humans and computers are linked more intimately than they ever have been before.

Bluetooth is a wireless technology that enables any electrical device to wirelessly communicate in the 2.5 GHz ISM (license free) frequency band. It allows devices such as mobile phones, headsets, PDA's and portable computers to communicate and send data to each other without the need for wires or cables to link to devices together. It has been specifically designed as a low cost, low power, radio technology, which is particularly suited to the short range Personal Area Network (PAN) application.  (It is the design focus on low cost, low size and low power which distinguishes it from the IEEE 802.11 wireless LAN technology).

Well...bluetooth is a wireless communications protocol.  In order to use bluetooth communications, you would need to have 2 devices that each have a bluetooth radio, and they need to be discoverable.  You will then pair the devices.  Sometimes you need to enter a PIN when pairing, it all depends on how you setup the devices.  Once you're paired you can send many types of files back and forth between the devices.  The range will also vary depending on what class bluetooth radio is in your device.  Class 1 radios can operate up to 100 meters, class 2 up to 10 meters and class 3 up to 10 cm.  Do a search on Yahoo or some other search site for "bluetooth communcation" and you'll find all the data you need.  Also, whatever device you have with a bluetooth radio in it should have instructions on how to use the radio.

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 and digital cameras via a secure, low-cost, globally available short range radio frequency.\n\nThe name Bluetooth was born from the 10th century king of Denmark, King Harold Bluetooth (whose surname is sometimes written as Bluetooh), who engaged in diplomacy which led warring parties to negotiate with each other. The inventors of the Bluetooth technology thought this a fitting name for their technology which allowed different devices to talk to each other.

Bluetooth is a technical industry standard that facilitates communication between wireless devices such as mobile phones, PDAs (personal digital assistants) and handheld computers, and wireless enabled laptop or desktop computers and peripherals. A single Bluetooth-enabled wireless device is capable of making phone calls, synchronizing data with desktop computers, sending and receiving faxes, and printing documents. For example, an individual can use a Bluetooth connection to print a document from his PDA. \n\nBluetooth devices use a microchip transceiver that operates on the 2.45GHz frequency and have a range of up to 10 meters (approximately 33 feet).

Bluetooth is usually used to create a wireless connection between two devices (in fact, Bluetooth is sometimes called a "cable replacement" for that reason).  But a piconet configuration uses Bluetooth technology to enable a group of devices to communicate wirelessly among themselves, under the control of one of the devices which acts as a master.

Nobody discovered a computer. It was invented. As far as who acctually invented the computer is still being debated to this day.

Maybe we should all do a little research before blindly answering questions.\n\nActually, the answer to your question is yes.  \n\nIt was first conceived in the 1990's at MIT, but the idea never resulted in a product because of superior emerging wireless technologies like bluetooth.\n\nNTT is now trying to make some products with it.  Their technology, called RedTacton Human Area Network, sends a 5V pulse along the surface of the body and purports to transfer data at 10Mbps.  See below sources for more information.\n\nMany people are skeptical as to whether it can compete with wireless technologies.
