CSR is estimating 15 to 20 per cent revenue growth for the next five years reaching $2bn by 2012.

The firm said its interim results with revenues of $376m, up 19 per cent on the same period a year ago point the way to high growth driven by the use of Bluetooth in products outside the mobile phone market.

Pre-tax profit was down in the half year, however, to $48.7m versus $69m a year ago. Q2 2007 contributed $44m to that figure but Q1 just $4.6m.

“The company continues to see a growth in the diversification of consumer applications using Bluetooth and in the medium term forecasts a substantial proportion of Bluetooth volume will be directed at non-cellular markets.

“In particular, CSR has identified MP3 and MP4 players, digital TV, gaming consoles, PCs, cars and cameras with additional applications continuously being identified,” said CSR.

In the portable music player market CSR has partnerships for Bluetooth and WiFi-enabled devices with Actions Semiconductor, Austria Micro Systems, Freescale and Telechips.

The automotive sector has also been increasingly making use of Bluetooth in new build cars. Ford has introduced a hands-free in-car communications system based on Bluetooth. “CSR expects the proportion of new build cars that incorporate Bluetooth to increase from the 6 per cent to 8 per cent seen today towards 30 per cent in the medium term,” said CSR.

CSR said beyond Bluetooth it is looking to lead the markets for GPS, Ultra-Wide Band (UWB), embedded WiFi and Ultra Low Power (ULP) Bluetooth and combination of these with Bluetooth and FM.

The firm also said it now has over 1,000 staff as a result of continued investment in research, sales, marketing, applications, engineering and operations. This is expected to further increase in the second half of 2007.
