Bluetooth

[frozenstar]

Everyone seems to be missing the point. Bluetooth wasn't designed for high data rates and long distances. There is no need for it to evolve to support services like real-time video and such. 802.11g already does that much better than Bluetooth ever will. But 802.11g consumes a lot of power, generates a lot of heat, and requires more physical space. Can you imagine building that into a mouse or a headset? Obviously not. THAT is where Bluetooth comes in.

yeah, bluetooth sucks for transferring large amounts of data its speed is somewhere around 700 - 800 KBps so compared to firewire its no good for transferring video. Maybe it could be pretty good for transferring still images from the camera.

If it was 700-800 KBps it would be faster than Firewire2. The spec for Bluetooth indicates it tops off at 1.0 Mbps hence the name 802.15.1. Much slower than even USB but it is wireless which makes an order of magnitude cooler.

edit: Sorry for being redundant. I didn't read all the other posts before I opened my fat mouth.'

Hi robbieduncan

What type of speeds are you getting using mobile as modem?

I was told that in Japan they have wireless speeds up to 700kbps over cell connections. Not that we'll see anything like that in the US for a long time.

Actually, 700-800 Kbps is 1000 times slower than Firewire 800, but nice try.

Sorry for the sarcasm, couldn't help it.

Not true. The current implementation of W-CDMA in Japan tops out at 384kbps. There is nothing faster. However, KDDI should be deploying CDMA2000 1xEV-DO soon which will allow for data rates as high as 2.4mbps.

In North America, we can expect to see speeds that high by the end of 2004.

Redezvous with Bluetooth

I know BT is not terribly fast yet, but wouldn't it be cool to auto-discover other BT devices that are rendezvous smart?

You could probably meet people and chat with them without any wires - or share music with someone with a BT enabled iPOD

You could connect to a fax or printer, you could connect to an smtp server to get your mail in/out.

When ithe BT bandwidth improves, then video
goes too...

Just the whole combo of BT + RV enables this realtime discovery and conspiry with people, devices and services. I'm up for that!!

Bluetooth Auto from Saab

There are some non-desktop/notebook computer items also taking advantage of bluetooth. Saab had a product video on their web site not too long ago for either the 9-3 or 9-5 demonstrating how it had integrated voice recognition (for the climate control, stereo, navigation system, etc.) with mobile communications - including bluetooth. The implications for this sort of car with a notebook may just be to use it as a large cell-phone, but there may be some nifty possibilities that don't spring to mind...

While I can no longer find the product film - here is a link to a story on the car:

http://www.itsa.org/ITSNEWS.NSF/4e0...c22539d01157b2ba85256c4000437e67?OpenDocument

Then again, maybe its just another device giving off a signal that can be used to track you as you pass by checkpoints - making your car into one big cookie, like a smart tag or EZ Pass. I mention this latter point as I was thinking that while the Wi-Fi 802 wireless networking standard is convenient - I'm sure Starbucks, and every marketing research firm out there, are excited to have an avenue to acquire more information on who uses their stores, when and for how long. Well - if it wasn't one of the wireless standards, I'm sure it would only have been a matter of time before Starbucks created scannable "bonus cards" like the supermarkets and bookstores to induce folks to let them record who bought how much and when by offering a small discount (although a discount is better than having to pay T-Mobile the fee to use the hot spot). I digress.

mac = small bluetooth component

I guess the point that I was missing is that my Mac really isn't a huge component of Bluetooth. It's a convienence issue. It sounds like it's more of a AirPort-ish solution for everything that doesn't have major processing power (cell phones, etc). So in that respect it makes a little more sense to me to have it on a computer.

Regarding "high=speed bluetooth" it seems like a much more worthwhile endeavor to adapt AirPort Extreme into smaller packages / componenets for use to transmit lots of data rather than sit around and wait for BT to get faster.

At the moment the best use (on a Mac) is to synchronise your contacts (from Address Book) and Calendars (from iCal) with your mobile devices. I use it to keep my Mac and my mobile phone (SE T68i) synchronised. You can also use the T68i as a modem through Bluetooth, send and receive SMS messages on your Mac through the phone (really cool). If you are on a call on your mobile whilst it is paired and someone else calls you a little window pops up on your Mac telling you this and offers you the choice of switching calls or rejecting their call (service provider dependant). You can also transfer pictures, ringtones and text notes to and from the phone using Bluetooth File Exchange.

Enough?

hi. can u pls. tell me how to transfer pictures?

t68i

I use a t68i and my laptop. It is great to use the phone for presentations or a remote for iTunes. But it sucks as a modem. 9600 is just too slow even for email when I get a ton of SPAM. You can get it higher if you use a GPRS connection but then the mobile company charges you per mb tranfered. Does anyone make a phone with a faster modem than 9600?

 

[Freg3000]

I love BlueTooth. I use it with my t68i to sync contacts, and use it between Macs for small files. I am really excited about the future of BT though, as I am aure that there are a lot of possibilities that have yet to be unlocked.
