Wibree, also called "Baby Bluetooth," is a low-power wireless local area network (WLAN) technology that facilitates interoperability among mobile and portable consumer devices such as pagers, personal digital assistants (PDAs), wireless computer peripherals, entertainment devices and medical equipment. Originally conceived by Nokia and developed in conjunction with Broadcom, CSR and others, Wibree is similar to Bluetooth but consumes a small fraction of the battery power. Wibree operates at a range of 5 to 10 meters (about 16.5 to 33 feet) with a data rate of up to 1 megabit per second (Mbps) in the 2.4-GHz radio-frequency (RF) band. Wibree may be deployed on a stand-alone chip or on a dual-mode chip along with conventional Bluetooth.
Bluetooth is a telecommunications industry specification that describes how mobile phones, computers and PDAs can be interconnected using short-range wireless connections. Bluetooth requires that a low-cost transceiver chip be included in each device. A technology called frequency-hopping spread spectrum allows devices to communicate even in areas with severe electromagnetic interference (EMI). Built-in encryption and authentication is provided.
