    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

    I wish that the future WLAN specs and products would use 5Ghz ISM band, like 802.11a and some HiperLANs do, but we'll have to see what's going to happen Juxo 16:50 Jun 5, 2003 (EEST)
