In this paper, we present architecture, circuit implementation and integration issues of an embedded smart system for innovative, long-range interconnected identification/sensor network in warehouse and intelligent goods distribution systems. The network is interconnected via IEEE 802.11 and ultra-wideband (UWB) wireless air interfaces. A self-powered, ultra-low power UWB transceiver with BPSK modulation is designed for transponders and implemented in 0.18 μm CMOS technology. Low power consumption is achieved by developing innovative circuit and system architectures. Instead of pumping up energy from the Gaussian pluses emitted by the reader, a power converter draws energy from the 802.11 access point and its surrounding electromagnetic waves. Functionality of the transceiver is verified and integration issues for smart labels are investigated on thin foils of liquid crystal polymer.
