Whats the difference between Bluetooth, Wifi, wireless LAN, 802.3 and Infrared ?

Bluetooth is a close range "connector" for the transfer of information (file sharing) or connections (mouse, headset for phone).  It has a range limit of approx 30ft.\n\na Wireless LAN is intended for connecting computers on a local network via the 802.11 standard (either a,b,g and eventually N.  the letter are modifications based on speed).\n\nWi-Fi is a Large Area Wireless LAN which provides a Wireless Connection.  Similar to a Wireless LAN, Wi-Fi is often associated with Open Access (i.e. a public location that offers Internet Connection to customers).\n\nInfrared or (IRda) is the technology now usually limited to Remote Controls.  Older PDA's and Laptops (and some newer ones for presumably compatibility purposes) used this as a way to provide Wireless before Bluetooth.  This technology is hampered by the fact that IRda requires "Line of Sight" between the two linking devices (for example if you put your and in front of the remote, it will not change the channel on the T.V.)\n\n802.3 is the 10GBase (10 GigaBit Networking) standard, and has nothing to do with wireless.  If you are confusing it will 802.11 see Wireless Lan.

Bluetooth technology is a cutting-edge open specification that enables short-range wireless connections between desktop and notebook computers, handhelds, personal digital assistants, mobile phones, camera phones, printers, digital cameras, headsets, keyboards and even a computer mouse. Bluetooth wireless technology uses a globally available frequency band (2.4GHz) for worldwide compatibility. In a nutshell, Bluetooth technology unplugs your digital peripherals and makes cable clutter a thing of the past.

Absolutely. I often connect via my phone. It needs to have a modem built in, you can connect via bluetooth, infrared or data cable and then you're away

bluetooth is a wireless standard used on may devices, like cell phone headsets and some electronic devices.\nit basically is a short area fm transmitter.

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.

There are many guides available on the internet.\n\nSimply search for "wireless networking guide".\n\nI linked a few in sources.\n\n\nAs far as best equipment to buy, the preferred (and popular) brands are Linksys, Belkin, and Netgear.

Add details to your question. We need to know the make and model of the computer what version of mac os it's running and the wireless equipment (router, switch, etc).

Bluetooth uses digital radio wave similar to WiFi

hahahaha lol its bluetooth but u can check out the nice new area51 m's that just came out and u can even order a usb bluetooth device on the same website...just visit alienware.com

You ither need a cable or a bluetooth/infrared...

PAN's\n\nPersonal Area Networks\n\nYou will wear or carry your device to access your files and email on the web.  Similar in concept to Blackberry but different in implementation.  I think Bluetooth will become the medium and Bluetooth nodes will just be everywhere.  You won't even think twice about looking up directions, email, placing calls, surfing, etc..

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).

Bluetooth or Infra red if your phone/ computer has them. You will need to set these up on your computer network settings though and adjust the firewall settings. Failing that most new ish phones come with a usb adapter that you can plug into your computer. If you have loaded the phone software on the PC then windows will identify the new hardware attachment when you plug it in.
