The Bluetooth Special Interest Group has said that the new version, Bluetooth 4.0, could be launching in the 4th quarter of this year with devices such as headsets, phones and PC’s all getting the technology.
The latest specification allows devices with smaller batteries to utilise Bluetooth. Previous versions of BT required that a device had at lease a AAA or larger capacity battery to function. The new 4.0 specifications allow for smaller devices that require coin-cell batteries to run.
As well as utilising less power, the device also has higher speed data transfer. Version 3.0 was launched last year although it kind of fell flat on it’s face due to the power requirements needed. Version 4.0 fixes those problems.
The new specification will carry the high-speed Wi-Fi feature introduced with Bluetooth 3.0. That allows devices to jump onto Wi-Fi 802.11 networks, where it can transfer data at up to 25Mbits per second.
Hopefully with the lower power requirements and the options to switch to 802.11 networks we should start seeing more devices using the Bluetooth specification.
