Wibree (Bluetooth Low Energy) - Wireless Technologies
Like Bluetooth, Wibree is a wireless communication standard for a short range which is 10 m(33 ft). It has been developed by Nokia Research Centre and is designed for ultra low power consumption. This is a relatively new technology and was released to public in October 2006 with brand name Wibree. In 2007 it was named as Bluetooth ultra low power and in 2008 Wibree was renamed Bluetooth low energy.
Some Facts about Wibree
Here are some important facts about this technology:
Radio frequency of the Bluetooth low energy or Wibree is 2.4 GHz. The original classic Bluetooth technology also operates at the same frequency.
Just like Bluetooth, it has a range of 10 meters.
When it comes down to energy consumption, Wibree is the best option. Lets say the energy consumed by Bluetooth is 1, then Wibree would use 0.1 to 0.5 depending on the use; this means it uses 10% to 50% energy as compared to Bluetooth. Also its peak current consumption is 15mA.
Application throughput of Wibree is 0.2 Mbps as compared to the 0.7-2.1 Mbps of Bluetooth.
It has over the air data rate of 1Mbps, while that of a Bluetooth ranges from 1 to 3 Mbps depending on radios.
Frequency: 2.4 GHz
Data transfer: 1 Mbps
Range: 10 meters
Cost: Almost the same as Bluetooth, thus inexpensive.
