Broadcom does not sell products directly to consumers. General Questions about Bluetooth. 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.

Broadcom offers Widcomm® Bluetooth protocol software for embedded systems (BTE), Windows (BTW), and Windows-CE (BTW-CE). All Widcomm software provides simple integration, powerful diagnostics and the shortest possible time to market. Bluetooth wireless technology and 802.11b/g both use the 2.4 GHz ISM (Industrial, Scientific, Medical) unlicensed spectrum, and in some configurations can interfere with each other. If the Bluetooth and 802.11b/g antennas are more than 3 meters apart, however, interface in minimal. Co-existence schemes such as adaptive frequency hopping have been implemented to address potential interference issues and Broadcom has introduced its InConcert® coexistence technology, which mitigates interference problems. 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, 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 2000 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. Product qualification is a way to ensure that Bluetooth products really do work together and a forum for demonstrating that a company's product complies with the Bluetooth specifications (per the Adopters Agreement).

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.
