1 Kilometer Bluetooth Link to Cell Phone 94
carbolic writes "WiFi-Toys.com has posted an article (with pics) about performing a Bluetooth connection over a distance of 1 kilometer. They claim it is a new world record. They used a Class 1 USB adapter modded using a kit from Bluedriving.com. The over-the-air connection went to an unmodified Sony Ericsson T610 at a distance of 'about 3,300 feet' and they transferred a few pictures. This test was to a paired device pre-configured for the built-in ObexFTP access, but the implication is that now it's easy to Bluesnarf without even being near the target phone."

There is more to it than that. Modulation is important. Bluetooth isn't meant to go more than 10m, wireless b and g can go up to 100m. wireless b has a few times more usable bandwidth.
You do get more Bluetooth channels though, 79 I think, so more people can use it without interfering wit

I'm a bit undecided on this concept. I love it as a principle of .+nix - I understand that each program generally does one task and this makes .+nix powerful.
But the problem seems to be with defining "one thing". What is one thing? Make calls? Recieve calls? Be my personal communications device?
So far, it seems to me that someone came up with this phrase "Do one thing and do it well." and it stuck, but noone really thought it through. It's kinda like the KISS - "Keep it sim

Another pic shows a picture of a hill, with a GIANT red hand-drawn arrow pointing to where the phone is. Picture #3 is the boot screen for the phone, courtesy T-Mobile. Then we get a blurry pic of the linksys bluetooth adapter with a giant cable coming off it...and last but not least...a picture of the bluetooth-raped cellphone..so traumatized, it has switched itself off.

The frequency hopping is a major factor. The psuedo-random hopping sequence is determined when the devices first connect. If you're not listening at that time (and know the device addresses of each), to get on track is far more difficult than it is worth. Remember its hopping ~1000 times a second.
