A long-range radio tag uses radio energy harvesting and separates the functions of radiofrequency excitation and radio tag reading such that the reader may be displaced at a substantial distance from the radio tags. The ability of the radio tags to communicate with a distant reader is further enhanced by a query system which allows a highly simplified message to be transmitted by the radio tags, as flexibly defined by a received query. The use of addressing and frequency multiplexing system allows a large number of tags to be serviced by a single reader.
