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\nBluetooth is a radio standard primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) and with a low-cost transceiver microchip in each device.\n\nBluetooth lets these devices communicate with each other when they come in range, even if they are not in the same room, as long as they are within up to 100 meters of each other, dependent on the power class of the product. Products are available in one of three power classes

Bluetooth is a short range radio protocol used to allow electronic devices to communicate. Bluetooth defines the protocol, not just the way to radio signal is to work.\n\nInfrared is a form of light that is also used for usually much shorter range communication. Unlike bluetooth, unobstructed line of sight is required for infrared to work (a major disadvantage). Infrared does not define a protocol so on its own is useless.

first you must be sure there is not physical error, for this try your blue tooth on other computer... if it is okay, it means there is soft ware problem, for solving this, uninstall drivers and reinstall. \n\nI hope it will work

wifi and bluetooth are totally different things and different technologies, although they are both 'wireless' technologies.\n\nthe chances of someone accessing your internet connection via the bluetooth on your laptop are incredibly slim, particularily since the data speed of bluetooth isn't very fast so browsing the internet via a bluetooth network connection isn't normally worth it.\n\nIF you have a wireless router with either a built in or connected modem then these are often open to abuse - especially if no security has been setup on them because anyone can connect to them wirelessly provided they're within the range of the router.\n\nIF you DO have a wireless router, you will need to read it's manual regarding enabling security settings. normally a wpa or wep should be set, and possibly mac address filtering too - these will stop just anyone using your router/internet connection.\n\nIF you DO NOT have a wireless router, it could be the case that your computer has been 'rooted' or otherwise compromised by a trojan which is allowing full access to your machine by an intruder. in this case you should disconnect from the internet and do a full virus scan to look for and remove trojans.

As far as I know mobile phones are coded telling itself and other bluetooth devices that it is a phone. I don't think there is a way, altho it's a good idea

Bluetooth is a telecommunications industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection. Using this technology, users of cellular phones, pagers, and personal digital assistants can buy a three-in-one phone that can double as a portable phone at home or in the office, get quickly synchronized with information in a desktop or notebook computer, initiate the sending or receiving of a fax, initiate a print-out, and, in general, have all mobile and fixed computer devices be totally coordinated. \nBluetooth requires that a low-cost transceiver chip be included in each device. The tranceiver transmits and receives in a previously unused frequency band of 2.45 GHz that is available globally (with some variation of bandwidth in different countries). In addition to data, up to three voice channels are available. Each device has a unique 48-bit address from the IEEE 802 standard. Connections can be point-to-point or multipoint. The maximum range is 10 meters. Data can be exchanged at a rate of 1 megabit per second (up to 2 Mbps in the second generation of the technology). A frequency hop scheme allows devices to communicate even in areas with a great deal of electromagnetic interference. Built-in encryption and verification is provided. \n\nThe technology got its unusual name in honor of Harald Bluetooth, king of Denmark in the mid-tenth century.\nOpen your control panel and find the "System" icon.Afterwards, find the "Device Manager" under "Hardware." After that, simply search for the infrared device. It will be easy to find from there if you have one. (Most especially if you are running Windows XP, but this will work with any os.)

Bluetooth is a technology that uses radio frequencies and infrared is a type of non visible  radiation that when applied to  computer communications task was called  IrDA.  Both IrDA and Bluetooth have similar technological objectives in providing solutions for wireless short range control and communications with computers, telephones, and other consumer devices.\n\n\nBoth technologies use radiation present in the electromagnetic spectrum at extremely low power levels to maintain their objectives of "short" range communications. The electromagnetic spectrum encompasses the entire range of ionizing and non-ionizing radiation extending in frequency from approximately 1023 hertz to 0 hertz, or in corresponding wavelengths, from 10-13 centimeter to infinity. This spectrum includes all forms of classical non-ionizing radiation we are familiar with including ultraviolet light, visible light, infrared (light) radiation, microwaves, and radio waves.  The spectrum also includes ionizing radiation such as cosmic-ray photons, gamma rays, x-rays. \n\nIt is well known that ionizing radiation such as cosmic-ray photons, gamma rays, x-rays even at low levels can cause damage to living organisms and such damage is bio-accumulative. \n\nThe effects of non-ionizing radiation such as ultraviolet light, visible light, infrared (light) radiation, microwaves, and radio waves also has known affects on living organisms.  For instance it is ultraviolet light from the sun that gives us both sun tans and a hazard from skin cancer.  Non-visible infrared from a fireplace can be comforting when it is cold outside.  We use microwaves to cook all kinds of food. \n\n\nThere appears to be no short term hazards in using  Bluetooth and Cellular phones.  However the question you pose has been the subject of global debate.  \n\nIt may seem obvious  but LONG TERM empirical  studies  of LOW LEVEL exposure to anything requires the passage of real time.       Such studies and experiments run concurrent  with the potential exposure of millions of people that may be using such technologies while they are being studied.    \n\nThe effects of using tobacco is a great example of a consumer product that was widely used, sold, and promoted without having information on the hazards.  Huge litigation settlements in this country suggest that much was known about the hazards of tobacco but this information was concealed from the public.

You need to make your PC capable of bluetooth just like you have to make your PC wireless to use wireless router.\n\nJust get a bluetooth adapter for your PC and as soon as you plug it in, you will be able to communicate with your motorola.\nGo here:\nhttp://www.amazon.com/gp/product/B0002WRGI0/104-1701409-7311150?v=glance&n=301185\n\nIts an example of what it looks like. You just plug it into your USB port. The software is downloadable on the internet or you can get it from Motorola.\n\nBluetooth headset works with your phone without wires. You just have to set your cell phone to connect with the bluetooth headset and you can use it immediately.

In general bluetooth makes only connections - like network adapter - so when installing it it search for active device on the other side - like mobile phone or keyboard. That's why its says that no active device found - but on restart you must have bluetooth icon on tray - so after you switch on some active device/s/ in /around/ range of bluetooth it must be found automatically - if not try to make it search for devices from icon in tray.\nHope this help

When a person speaks into a telephone, the sound waves created by his voice enter the mouthpiece. An electric current carries the sound to the telephone of the person he is talking to. A telephone has two main parts: (1) the transmitter and (2) the receiver.\nThe Transmitter of a telephone serves as a sensitive "electric ear." It lies behind the mouthpiece of the phone. Like the human ear, the transmitter has an 14 eardrum." The eardrum of the telephone is a thin, round metal disk called a diaphragm. When a person talks into the telephone, the sound waves strike the diaphragm and make it vibrate. The diaphragm vibrates at various speeds, depending on the variations in air pressure caused by the varying tones of the speaker's voice.\n\n\nBehind the diaphragm lies a small cup filled with tiny grains of carbon. The diaphragm presses against these carbon grains. Low voltage electric current travels through the grains. This current comes from batteries at the telephone company. The pressure on the carbon grains varies as sound waves make the diaphragm vibrate. A loud sound causes the sound waves to push hard on the diaphragm. In turn, the diaphragm presses the grains tightly together. This action makes it easier for the electric current to travel through, and a large amount of electricity flows through the grains. When the sound is soft, the sound waves push lightly on the diaphragm. In turn, the diaphragm puts only a light pressure on the carbon grains. The grains are pressed together loosely. This makes it harder for the electric current to pass through them, and less current flows through the grains.\n\n\nThus, the pattern of the sound waves determines the pressure on the diaphragm. This pressure, in turn, regulates the pressure on the carbon grains. The crowded or loose grains cause the electric current to become stronger or weaker. The current copies the pattern of the sound waves and travels over a telephone wire to the receiver of another telephone.\n\n\nThe Receiver serves as an "electric mouth." Like a human voice, it has "vocal cords." The vocal cords of the receiver are a diaphragm. Two magnets located at the edge of the diaphragm cause it to vibrate. One of the magnets is a permanent magnet that constantly holds the diaphragm close to it. The other magnet is an electromagnet. It consists of a piece of iron with a coil of wire wound around it. When an electric current passes through the coil, the iron core becomes magnetized. The diaphragm is pulled toward the iron core and away from the permanent magnet. The pull of the electromagnet varies between strong and weak, depending on the variations in the current. Thus, the electromagnet controls the vibrations of the diaphragm in the receiver.\nThe electric current passing through the electromagnet becomes stronger or weaker according to the loud or soft sounds. This action causes the diaphragm to vibrate according to the speaker's speech pattern. As the diaphragm moves in and out, it pulls and pushes the air in front of it. The pressure on the air sets up sound waves that are the same as the ones sent into the transmitter. The sound waves strike the ear of the listener and he hears the words of the speaker.

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.
