wireless technologies or wibree technology

abstract

Nowadays the wireless technologies are more in use and are widely evolving. Some of the technologies now in use are Wi-Fi, Wi-max, Zigbee, Bluetooth… Out of which Bluetooth is most popular. These technologies are widely used to connect the large devices like mobile phones or personal computers. No other existing wireless technologies will connect with small button cell battery devices so effectively. So the Nokia introduced the new radio technology called Wibree.


Wibree is a new radio wireless technologies technology developed by Nokia. It consumes only a fraction of the power compared to other such radio technologies, enabling smaller and less costly implementations and it is easy to integrate with Bluetooth solutions. Wibree is the first open technology offering connectivity between mobile devices or personal computers, and small, button cell battery power devices such as watches.

Wibree is ultra low power technology. The maximum transmitted output power of Bluetooth class 2 is 4dBm, (~ 2.5 mW). The total power consumption is much higher. The output power of Wibree standard will be around -6dBm. Each manufacturer will determine its own transmit power.

In order to ensure fast availability of the new technology, Nokia is defining the Wibree interoperability specification together with a group of leading companies representing semiconductor manufacturers, device vendors and qualification service providers.
