Wibree
wibree
Now a days 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.
The name for the new low-power wireless standard called wibree is an amalgam of "Wi," for "wireless," and "bree," from an Old English word for "crossroads," or a place where two things come together.
What is Wibree?
.New radio technology for ultra low power applications
.Open industry initiative
Why is Wibree needed?
.Ultra low power cannot be achieved with existing open standards
FEATURES
.Wireless Technology .Cheaper than the bluetooth wireless communication. .Lower power consumption .Use same frequency of Bluetooth (2.4GHz) .Small chip size .10 times more energy efficient than Bluetooth .Inexpensive implementation .Easily integrated with Bluetooth solutions
Advantages
.Ultra-low power consumption .Long battery life .Use same frequency of Bluetooth (2.4GHz) .Small chip size .10 times more energy efficient than Bluetooth .Inexpensive implementation .Easily integrated with Bluetooth solutions
Disadvantages
.Data transmission is very slow, i.e. only 1Megabit per second
.Cannot be used in high bandwidth required applications
WIBREE IMPLEMENTATIONS
Wibree stand-alone chip The Wibree stand-alone chip is designed for use with applications which require extremely low power consumption, small size, low cost and where only small quantities of data are transferred.
Wibree-Bluetooth dual-mode chip The Bluetooth-Wibree dual-mode chip is designed for use in Bluetooth devices.
The link layer is strictly stateful - every packet is acknowledged before the next one is sent. If a packet does not go through - if no re-transmission induces an acknowledgment - the link will be terminated whereafter a new one possibly is initiated. The roles in communication are _xed. A target device
