A wireless digital network communication system built on the basis of novel radio transmitting devices is presented. We propose to use passive nonlinear scatterers reradiating an electromagnetic field instead of active transmitters. The developed approach allows to implement communication system which has essentially lower power consumption and is cheaper and easier to construct than conventional ones. The present paper describes an experimental study of a system collecting information from the sensor network nodes.
