If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update, or contact the device manufacturer. Broadcom supplies Bluetooth hardware and software solutions for various PC, Pocket PC and mobile terminal products. Broadcom does not sell products directly to consumers. Bluetooth wireless technology is an international open standard for allowing intelligent devices to communicate with each other over short range wireless links. It allows any sort of electronic equipment - from computers and cell phones to keyboards and headphones - to make its own connections, without wires, cables or any direct action from a user.

A distinctive advantage for Bluetooth wireless technology is its low power consumption, enabling extended operation for battery powered devices like cell phones, personal digital assistants, and web tablets. Bluetooth wireless technology includes both hardware and software components. The hardware consists of a Bluetooth module or chipset, which is comprised of a Bluetooth radio transceiver and baseband or a single-chip that contains both. Another part of the hardware is the antenna. The radio transmits and receives information via the antenna and the air interface.

The chip also contains a digital signal microprocessor, which is part of the baseband. The key functions of the baseband are piconet and device control - for example, connection creation, frequency-hopping sequence selection and timing, modes of operation like power control and secure operation, and medium access functions like polling, packet types, packet processing and link types voice, data, etc.

The software consists of the protocol stack. All Widcomm software provides simple integration, powerful diagnostics and the shortest possible time to market. Bluetooth is primarily a cable replacement technology, enabling users to connect to a wide range of computing and telecommunications devices without using cables.

The real magic of Bluetooth wireless technology lies in the concept of a Personal Area Network PAN and ad hoc connectivity. Through the Discovery Service, PAN devices are capable of spontaneously joining into a network as they approach each other. This occurs only while the devices are in close proximity: The opportunity for automatic, unconscious connections between mobile devices provides new freedom for end-users. But these same features are also limiting for Bluetooth wireless technology and Depending on the specification of the device, Bluetooth wireless technology works within a to foot radius.

Bandwidth allocation is very flexible, and completely under the control of the device which establishes the connection. Security is a critical issue in any wireless system Bluetooth provides several components that ensure secure wireless connections.

First, at the highest level, the application itself can provide authentication and encryption, and is used in the most critical applications. Second, the Bluetooth specification provides for authentication and flexible encryption at the baseband level.

The third level of security is based on the transmitter characteristics of low power and frequency hopping, which helps deter casual eavesdroppers.

Bluetooth wireless technology is different from historical wireless standards in that it is an open standard that is consistent worldwide. The Bluetooth Special Interest Group SIG , comprised of leaders in the telecommunications, computing, and network industries, is driving development of the technology and bringing it to market.

The Bluetooth SIG includes promoter companies 3Com, Ericsson, IBM, Intel, Lucent, Microsoft, Motorola, Nokia and Toshiba, and more than adopter companies. The goal of the SIG is to promote the standard, ensure interoperability, define the radio characteristics, link protocols and profiles, and provide free access to the Bluetooth standard.

The benefits to producers include standardized connectivity and protocols, opportunities for product enhancement and differentiation, and reduced interoperability concerns. Broadcom is an associate member of the Bluetooth SIG and participates in various Bluetooth SIG working groups. The qualification process involves protocol conformance tests, profile interoperability tests, compliance declarations and documentation reviews as described in the Bluetooth Qualification Program Reference Document PRD.

The PRD defines the specific test standards and criteria that must be met by hardware manufacturers and software developers in order to receive qualification. Interoperability means plug and play operation with full compatibility among products from different manufacturers. Each manufacturer must send their products to a Bluetooth Qualification Test Facility, which performs interoperability tests under controlled conditions. Unplugfests are an informal forum to determine interoperability issues. Broadcom has been attending Unplugfests since they first started in He was the son of Gorm the Old, the King of Denmark, and Thyra Danebod, daughter of King Ethelred of England.

Harald was responsible for peacefully uniting Denmark and Norway. Bluetooth wireless technology unites devices such as PDAs, cellular phones, PCs, headphones, and audio equipment, using short-range, low-power, low-cost radio technology.
