Ask the SIG | Q4 ’07 Experience More What is Wibree and why is it being merged with the Bluetooth SIG? Bluetooth stack Bluetooth / Wibree stack (dual-mode) Wibree stack (standalone) Wibree is an ultra low power radio technology developed by Nokia for use in small devices, such as watches, gaming and sports sensors, that connect to host devices like personal computers and mobile phones. Wibree is optimized for embedded applications that require extremely low power consumption, small size and low cost, rather than high-data-rate voice and audio applications. Our expertise, large membership and resources like the qualiﬁcation program will help ensure interoperability and further development of Wibree. How will this integration beneﬁt Bluetooth technology? Wibree technology Bluetooth Profiles Bluetooth Profiles L2CAP Wibree Profiles PAL Wibree Profiles L2CAP PAL Admission Control HCI HCI + Extension HIF Wibree technology addresses devices not currently served effectively by Bluetooth wireless technology: smaller devices with ultra low power requirements. An ultra low power Bluetooth wireless solution will enhance current use cases and enable new ones, providing greater access to untapped markets such as sports and wellness, health care, entertainment devices and toys. Wibree is a good ﬁt for Bluetooth technology because it tightly complements existing solutions and market sectors. With Wibree on the ultra low power end and UWB on the high-speed side, Bluetooth technology provides the full circle of wireless options, positioning it to become the default technology for connecting all sorts of devices with varying power needs. How is Wibree implemented with Bluetooth technology? LM DuMo Manager Link Manager (LM) Link Coordinator (LC) RF LL Link Layer (LL) LC RF Wibree was designed for implementation either as a standalone chip or as a dual-mode chip incorporating Wibree and Bluetooth technologies. Small devices like watches and sports sensors will be based on the standalone chip, whereas Bluetooth enabled devices like mobile phones and PCs will beneﬁt from the dualmode chip, which will extend Bluetooth enabled device connectivity to a range of smaller devices. Wibree’s power consumption in dual mode is ultimately dependent upon how a product uses Bluetooth technology. Dual-mode implementation uses parts of the Bluetooth wireless hardware and shares one physical radio and antenna. When will the ultra low power Bluetooth wireless technology interoperability speciﬁcation be ready, and when will the ﬁrst products arrive on the market? Physical Layer (PHY) Wibree Technology Protocol Stack Why Wibree? Since its announcement in October 2006, Nokia has sought to widen Wibree’s availability by incorporating it into an existing forum, and the Bluetooth SIG, Inc. is the optimal forum for this new technology. The combined solution, called ultra low power Bluetooth technology, is another milestone on a wireless road with No Limits Ahead. According to current estimates, the ﬁrst commercial version of the interoperability speciﬁcation will be available during the ﬁrst half of 2008. In the second half of 2008, we should begin to see the ﬁrst standalone products (small button cell battery-powered devices) from a variety of vendors. Host devices and other dual-mode devices should emerge in the ﬁrst half of 2009. How can members help advance ultra low power Bluetooth wireless technology? Have a question for the Bluetooth SIG? Want to share an answer to a Frequently The new Ultra Low Power and Remote Display Working Asked Question from your customers? Groups will help develop the ultra low power speciﬁcation. E-mail us at signature@bluetooth.com. In addition, the Automation, Human Interface Device and Medical Devices Working Groups will be expanded to incorporate enhancements for ultra low power Bluetooth technology. Promoter and Associate members are strongly encouraged to join these working groups. Bluetooth Special Interest Group | 11
