A new 2.2 bluetooth version is now being developed by a group of professional team. It is expected to give a 100 times faster speed than the current 2.0 speed.
At the same time, Nokia Siemens Networks declared to increase the data transfer through EDGE to 592 kb/sec. It's a change only on soft level. Besides, Nokia Siemens prepares the technology EGPRS 2B, which will raise the data transfer speed to 1.2 Mbits/sec. Can't wait to see and test all these!!!
