A 2-Mb/s, UHF-band, wireless sensor node for real-time multi-point sensing

A 2-Mb/s, UHF-band wireless sensor node constructs a network capable of high-speed data collection from multiple sensing points. A relatively high data-rate of 2 Mb/s ensures TDMA-based real-time sensing in a network of a maximum of 63 sensor nodes. Using a carrier frequency in the UHF band simplifies the RF section in the node and thus saves area and power. 1-V CMOS/SOI technology integrates some of the transceiver circuit on a silicon die and further reduces node area and power. A battery-operated, prototype circuit board occupies only 6.5 cc and demonstrates wireless sensing of multiple nodes.
