Enhanced RFCMOS Paves the Way for UWB Systems
Ultra Wideband (UWB) wireless systems are capable of delivering extremely high data rates with little interference and excellent frequency diversity. These transmission properties allow high performance systems to be designed at frequencies that can be implemented using enhanced RFCMOS IC technologies.

Software Defined Radio for Wireless Devices
Wireless in the commercial world started in the late 1980s with the advent of car-phones and 2 lb. handsets that cost more than $2000.

This problem has mostly been solved; we now have phones that barely weigh a couple of ounces and cost less than $40. The next challenge for the industry was to evolve the handset from a purely voice communications device to a multifunction device that is capable of handling data, video, music, and graphics as comfortably as voice.
