Bluetooth 4.0 will be here soon

Bluetooth 3.0 is barely ready yet, but version 4.0 has already been finalized.

The novelty of the new version will be mainly energy saving, which will allow the technology to be used even more widely.

With the new standard, the current range of approximately 10 meters increases to approximately 60 meters. The version of Bluetooth 3.0 has not yet become widespread among mobile phones, except for some Samsung models. Most new phones today still use the 2.0 or 2.1 standard "blue tooth". The first 4.0 device is expected to arrive by the end of 2010. And phone manufacturers will certainly take a step forward and use the 2.0 standard immediately after 4.0.
