Information on Future Bluetooth Specifications

Bluetooth 1.2

  • Backward compatible with 1.1
  • Baseband platform already available from Ericsson Techonology Licensing
  • Adaptative Frequency Hopping (AFH) provides better immunity to interference from other devices (such as 802.11 devices)
  • Scatternet ability (Running multiple Piconets simultaneously, making it possible to interconnect piconets)
  • Extended SCO (ESCO) (whatever that means)
  • Improved QoS
  • Faster connections then in 1.1


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
