Wibree[1] is a digital radio technology (intended to become an open standard of wireless communications) designed for ultra low power consumption (button cell batteries) within a short range (10 meters / 30 feet) based around low-cost transceiver microchips in each device.

Wibree is designed to work side-by-side with and complement Bluetooth. It operates in 2.4 GHz ISM band with physical layer bit rate of 1 Mbps. Main applications include devices such as wrist watches, wireless keyboards, toys and sports sensors where low power-consumption is a key design requirement. The technology was announced 2006-10-03 by Nokia. Partners that currently license the technology and cooperate in defining the specification are Nordic Semiconductor, Broadcom Corporation, CSR and Epson[2]. Other contributors are Suunto and Taiyo Yuden.

Bob Iannucci, head of Nokia's Research Centre, claims the technology is up to ten times more efficient than Bluetooth.[3] It will reportedly have an output power around -6 dBm.[4] Nordic Semiconductor is aiming to sample Wibree chips during the second half of 2007.[5]
