We propose a "wide area ubiquitous network" as a highly economical and convenient wireless system for providing a wide variety of services. Its basic feature is "wide coverage using ultra low power consumption terminals," and its specific target is a "5-km cell radius using 10-mW transmission power terminals run on ten--year life batteries."

This paper presents design methodology for CMOS RF-ICs in the 2-GHz bond. After describing RF transceiver architectures, it introduces some low-voltage, low-power CMOS front-end circuits that use an LC-tank folding technique. Finally, it presents a 1-V, 12-mW image-rejection receiver in the 2-GHz band.
