Bluetooth SIG Adopts Bluetooth v1.2
The Bluetooth Special Interest Group (SIG), the trade association responsible for Bluetooth wireless technology, has announced the adoption of Bluetooth Specification Version 1.2. The update includes new features for a more reliable and easier user experience.
The adoption of Bluetooth Core Specification Version 1.2 is the perfect example of what an industry can accomplish together in creating a standard, said Mike McCamon, executive director of the Bluetooth SIG. All of the work to complete this specification was done by the members, for the members of the Bluetooth SIG. It is a huge accomplishment.
This new version of the Bluetooth Core Specification was designed for developers by developers with a view toward a more positive user experience and the future wireless world. The current specification is included in over 1000 products as diverse as computer mice and mobile phones to automobiles and various computing products. Version 1.2 is also intended to set the stage for the development of a growing number of mainstream products such as more feature rich mobile phones, headsets, PDAs, digital music players, cameras and laptops in a consumer's Personal Area Network.
The Bluetooth Core Specification Version 1.2 introduces a host of new features intended to make Bluetooth wireless technology easier and more reliable to use:
- Adaptive Frequency Hopping (AFH) AFH was explicitly designed to reduce interference between wireless technologies sharing the 2.4 GHz spectrum. Cordless telephones, microwave ovens and certain Wireless Local Area Networking (WLAN) technologies, including IEEE 802.11b and IEEE 802.11g, generally share the same wireless frequencies as Bluetooth wireless technology. AFH works within the spectrum to take advantage of the available frequencies without limiting the Bluetooth transmission to a set of frequencies occupied by other technologies. This 'adaptive hopping' allows for more efficient transmission within the spectrum, thereby providing the user with greater performance, even if using other technologies along with the Bluetooth wireless technology.
- Enhanced Voice Processing This feature is designed to improve the quality of voice connections, particularly in noisy environments, using error detection methodologies.
- Faster Connection Setup This version of the wireless technology allows for even faster connections to other Bluetooth wireless devices, thus improving the user experience.
- Backward Compatible As a core feature, the new version of the Bluetooth Core Specification is backward compatible with 1.1 Bluetooth Core Specification Version 1.1 products, allowing users of nearly all existing Bluetooth equipped devices to easily work with products built to the new Specification.
The Bluetooth Core Specification Version 1.2 incorporates changes that are meaningful to all of the industries that can make use of Bluetooth wireless technology in their products, added McCamon. Version 1.2 is especially exciting for the personal computing industry, however, because of the adaptive frequency hopping feature and the realm of possibilities it opens up for complimentary wireless technologies like Bluetooth and WiFi to coexist in the PC.
Consumer products that incorporate the new version of the Specification are expected to begin shipping in the next quarter, with greater volumes arriving in the market over the next 1218 months.
