Power Consumption Trade-offs in Short-distance Wireless Transceivers for Sensor Nodes

This paper reviews system level considerations for the design of Ultra Low-Power Radio (ULP radio) transceivers with the capability to operate at short distances (similar to 1m) with a data rate of 1 Mbit/s and with a very low power consumption (similar to 1mW); the target application is a Sensor Node (SN). It is shown that under practical constraints an Ultra-Wide-Band impulse radio architecture (UWB-IR) is more power efficient than narrow-band modulated carrier approaches for the same bit-error rate (BER) performance.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000287267300037&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Computer Science, Hardware & ArchitectureEngineering, Electrical & ElectronicTelecommunicationsEICPCI-S(ISTP)
