The Bluetooth Special Interest Group (SIG) recently formalized the Bluetooth 4.0 and hopes to market the first products during the last quarter of this year.
Low power consumption and better performance
As we have explained in our columns, the big news of this standard is the ability to reduce energy demand controllers so they can be integrated in very small items (watches, sensors, etc..) Without an impact on the autonomy of these tools batteries often very limited.
Consumption is comparable to an RFID chip and the module uses a 2.4 GHz ISM band relatively impervious to interference. If you want better performance, this standard offers a bandwidth of 24 Mbps and the ability to communicate directly with wireless controllers
Specifically, the Bluetooth SIG Qualification Program is officially open, allowing manufacturers to certify their products. The group in charge of this standard considers that this new version will be much more popular than Bluetooth 3.0, which really begins to be marketed.
