Technical specifications

The Digitag-F type DTFT01 is a radio active tag, operating at 
433,92 MHz in GFSK modulation.
The tag transmits continously a radio pulse with a period of 1 sec. 
A  special  algorithm  adds  to  the  rated  time  period  a  small  slot, 
realizing,  in  this  way,  an  anticollision  system,  which  avoids  the 
overlapping  of  the  RF  signals  of  many  tags  when  standing 
simultaneously in the same field.
