Technology RoadmapTo Developing the Universal Radio

• Move the Problem to the Digital Domain– Today’s GSM Phone uses 100 MIPs

– The GSM channel implemented in the digital domain requires over 500 MIPs without decimation techniques

– With appropriate pre-filtering, GSM channel filter can be only 5 MIPs… Not Applicable !

• No Talk-Time Degradation

• Battery Capacity Improved Barely 10% in 40 years!
