Why was bluetooth invented?

[sygyzy]

Silly question to some, but I cannot figure out the beneifts of bluetooth. It does not do anything that cannot already be done. It is wireless but has a very short range. You are telling me that running a 4 foot cable from your PC to your printer is too much of a hassle? Wireless mouse and keyboard? They already had that before bluetooth. Need to communicate between your phone and pocket pc? They have infrared. Infrared, RF, lasers, all do the same thing.

I guess the bandwidth is a plus but nothing that uses it requires much bandwidth! Do you run a kinkos? Probably not, so your document queues to the printers are probably < 1 MB.

Anyone have any really good pros for bluetooth?

 

[notfred]

cause running cables under desks is a pain in the ass and looks crappy.

Browntooth and Yellowtooth were already invented, so they had to come up with a new variation.

You can put a tiny earpiece in your ear and have your cellphone in your pocket, and there's no wires. That'd sell me in a second if I talked on my cell phone a lot.

Yea, the fact that it can operate on hardly any electricity is one of the reasons for creating bluetooth. All other wireless standards are energy leaches. It was also supposed to be very inexpensive to produce, which would make it easy and cheap to implement, and it wouldn't cost the user much electricity. No other wireless standard is as easy to implement into products.

i can now upload pics from my camera phone easily, vids, software etc.

its bluetooth

penblue dongles are 30 shipped off ebay.

ultra cheap wireless lan for your notebook, for casual surfing.

wireless printer sounds good. and wireless pda interface would be nice too.

Bluetooth was developed by a consortium of companies to create a short range wireless standard. The goal was to offer security, low power consumption, high speed (relatively speaking), and compatibility between any bluetooth enabeled device. In addition, Bluetooth can pull some serious ad-hoc networking stunts. Up to 80 (IIRC) bluetooth enabled devices can be be collected into an ad-hoc networks called piconets. Bluetooth has implications that reach FAR beyond computers. Developing the standard took quite a while, as it was a joint effort from so many companies. Also, 802.11 standard was rising rapidly in popularity hiding Bluetooth in it's limelight. It's a shame really. Bluetooth has some really unique and intersesting abilities that I would love to see implicated. Perhaps it will at some point.

FYI...I know all of this because I did an ENORMOUS semester-long research project on Bluetooth.

I think it was more aimed at Mobile phones for handsfree kits and such like

The idea seems great. Walk into a room with your PDA and print instantly and what not. I was about to order a bluetooth USB adapter from newegg but then I realized I have nothing to use it with yet. Means its time for a new PDA and cell phone What would be great is if BT took the place of usb. I have so many of those cables snaked around my desk! One day will be a world without wires; perhaps only for power.

Another thing I forgot to mention about Bluetooth, is that it was designed to be very low cost. When I say low cost, I'm talking only a few dollars a chip. The idea was to put a Bluetooth chip into every electronic device, enabling communication between everything!

 

[vi edit]

I think it falls under the "great idea, piss poor marketing" category.

It is very cool stuff, it just isn't marketed well.

Points addressed randomly

1. The wireless headset to your cell phone on your belt is one of the first things they came out with. Horrible idea. So expensive for 2.5 feet of wires! I really do not see the point of being wireless when it's so "close".
2. You can have wireless internet already, it's called 802.11
3. Is it really that more inexpensive than say IR or radio waves?

Have you tried using wired headsets in the car? THEY SUCK!!!!! A completely wireless earbud is an excellent idea.

The whole point of bluetooth is that its made to be seemless. 802.11 requires configuration and setup. Even then it may not work properly. BT is something made to plug in, turn on and work. Its that simple.

If those retards at Nintendo had bothered to include Bluetooth on-board the GameBoy Advance instead of using some moronic link cable, you would be asking why 802.11 was invented when we've already got Bluetooth repeaters on every telephone pole and toddler.

LOL!!! Yeah, I see what you mean..

I use BT almost every day. I have a Sony Ericsson T68i, and BT dongle for my computer (PowerBook running OS X 10.2.6), and a BT headset (Jabra BT200). The tight compatibility between these devices just makes me so glad that I bought them every time I use them. It really is nice. And I know that a wire between your ear and a cell phone in your pocket isn't such a big deal, but I'll never use anything other than wireless BT headsets from now on.

Eventually I'm going to get a BT PDA, and maybe a BT keyboard/mouse setup.

Can you make a call with your cell phone in your pocket and that earpiece in your ear? Can you talk to someone? Where's the microphone?

The mic is on a boom attached to the earpiece.

Shortrange wireless, small footprint, extremely low power consumption.

If you tried running 802.11 on a cell phone battery, you'd end up charging your phone several times daily.

depends on your idea of cost. they make 500 dollar cellphones after all. wired headsets are rather annoying to carry around, and untangle etc. do some pay for convenience? sure why not. i've seen em low as 60 bux, not bad at all for new tech.

 

[BatmanNate]

I figured it would come in handy to use the internet via cellphone from a PDA or laptop. Also the '04 Toyota Prius is supposed to have a bluetooth interface. :Q

 

[ElFenix]

isn't 802.11 much higher bandwidth than bluetooth?

Yes, but other than huge file transfers who actually taxes out 802.11b?

 

[bolido2000]

How secure is BT? Could someone easily hack into cell phones and PDA in the future?
