By designing a digital RF CMOS architecture, TI has removed many of the challenges associated with current RF devices. The BRF6100 Bluetooth chip will consume as little as half the power of current solutions and will occupy the smallest board area of any product available today. The BRF6100 will allow mobile device designers to easily integrate Bluetooth functionality -- a high value-added feature -- for a total system cost below $4 in volume quantities."

This may be the drop that overflows the river banks because price point has been such a huge obstacle to Bluetooth adoption. Getting the price of a chip below $5 was a necessary step to mass production.
