The popularity of mobile phones with wireless capability has helped a UK firm more than double its profits in the first three months of 2006.
Up to 40% of mobiles will feature Bluetooth by the end of 2006
CSR specialises in supplying Bluetooth technology, which enables devices such as computers and mobiles to talk to each other without cables.
The firm predicts the percentage of mobiles with Bluetooth will rise from 25% in 2005 to 35-40% by December 2006.
CSR saw pre-tax profits climb 137% to £14m in the quarter to 31 March.
The Cambridge-based firm said the popularity of hands-free devices for mobiles had driven business.
It counts phone manufacturers including Nokia, Sony and Samsung among its customers while IBM, Apple and Dell are among the companies using CSR products in their computers.
CEO John Scarisbrick said the overall Bluetooth market would grow by 60-70% in 2006 - faster than it had previously forecast.
Sales rose 103% to £73.5m in the period.
