Patent Images
1. A controlling method for a radio-frequency identification system operating between a reader and a tag, the controlling method comprising:
- transmitting a signal from the reader to a transmission device;
setting parameters of the transmission device depending on the demands of the radio-frequency identification system after the transmission device receives the signal via a receiving antenna of the transmission device;
transmitting the signal that is processed from the transmission device to the tag via a transmitting antenna of the transmission device; and
simultaneously the transmission device receiving and collecting signals outputted from the tag, whereby the tag is applied in multi-function and long-path manner depending on parameters of the radio-frequency identification system.

2. A transmission device for a radio-frequency identification system operating between a reader and a tag, the transmission device comprising:
- a receiving end; and
a transmitting end, wherein a signal outputted from the reader is received via a receiving antenna of the receiving end, the signal is processed depending on parameters set by the radio-frequency identification system, the processed signal is sent to the tag via a transmitting antenna of the transmitting end of the transmission device, and simultaneously the transmission device receives and collects a signal sent back from the tag, whereby the signal processed by the transmission device is high-power and high-identified so that the radio-frequency identification system can provide more complex identification.
- a receiving end; and
