Line 1: | Line 1: | ||
===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 [[Piconet]]s 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 [[User:Juxo|Juxo]] 16:50 Jun 5, 2003 (EEST) | 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 [[User:Juxo|Juxo]] 16:50 Jun 5, 2003 (EEST) |
