CSR designs single-chip wireless devices. Our business started with a focus on solutions for the 2.4GHz Bluetooth?personal area networking standard; in November 2004, we entered the IEEE 802.11 marketplace - a family of wireless standards also referred to as ''WiFi'' or ''Wireless LAN'' - with devices capable of operation in both the 2.4 and 5GHz frequency bands.

CSR''s leading position in the Bluetooth business has been won by a unique approach to IC design based on extremely high levels of integration, providing compelling performance and cost advantages to OEMs. This brand ethos has been carried through to 802.11 applications, with an IC architecture that integrates a new level of functionality embracing all three major variants of the protocol (802.11a, b and g), and IC choices that offer solutions for both current applications, and emerging embedded applications in portable consumer electronics devices (including mobile phone handsets) and home appliances.

In the Bluetooth market, CSR is ranked #1 in every Bluetooth market segment with a unit market share in excess of 50%.

CSR''s BlueCore?ICs are used in all principal applications including mobile phones from BenQ, HTC, Motorola, NEC, Nokia, Panasonic, Samsung and Sharp; wireless headsets from Hutchison ''3'', Jabra, Logitech, Motorola and Plantronics; almost all new models of laptop personal computers with Bluetooth capability introduced since 2003 (including Apple, Dell and IBM), mice and keyboards from Logitech, and in-car communication systems used in SAAB, Audi & BMW motor vehicles. BlueCore?ICs are also approved by Microsoft for use with its Windows operating system. For a comprehensive list of products that our silicon features in, check: www.btdesigner.com.
