Bluetooth 2.0

Many would argue that Bluetooth 1.x is still half-baked, at least in regards to some of the products on the market out there now, but the creators of Bluetooth are pushing ahead with the 2.0 spec. More bandwidth is always nice, but they mention that it's "non-hopping" which will defeat one of the major security features of Bluetooth. Still, with a range of 10 meters, it's still a personal area network so hacking is unlikely (but not impossible).
"A scientist at Ericsson Technology Licensing has leaked the basic features of the upcoming Bluetooth 2.0 wireless communications specification targeted at personal-area networks, which has been kept under wraps by the standards-setting Bluetooth Special Interest Group. The 2.0 spec is expected to support gross rates of 4, 8 and 12 Mbits per second, said chief scientist Jaap Haartsen in a speech prior to the Bluetooth Congress here.
The 2.0 spec will offer new communication modes on top of the current Bluetooth by using "a non-hopping narrowband channel and distributed media-access control protocols," said Haartsen. The higher-rate mode is also designed to provide "faster response times and built-in quality-of-service, and offer broadcast/multicast support," he said. Bluetooth 2.0 is expected to operate over the same 10-meter distance as the present Bluetooth. Its peak power consumption is expected to be double that of the current Bluetooth."
