Bluetooth 2.0

First news/rumors

• Backward compatible with 1.1 and 1.2
• This version is rumored to contain new speeds of 4,8 and 12 Mbps.
• A new way of communication: non-hopping narrowband connections, which sounds like a broadcast channel that can be read by all devices in the coverage area.
• 2.0 dispenses with the master/slave situation making every device able to keep a piconet running, while as in the 1.1 spec if the master leaves the piconet is dropped for all slaves
• The release of the 2.0 specification will propably be delayed to 2004, even though there are already prototypes running in Ericssons labs
