Title:
送受信プロトコル変更が可能な無線周波数タグを含む無線周波数認識システム
Document Type and Number:
Japanese Patent JP4694236
Kind Code:
B2
Abstract:
A radio frequency (RF) tag is provided with an antenna coil adapted and configured to wirelessly exchange data with a read/write terminal, a RF transmitting/receiving unit adapted and configured to modulate and demodulate data exchanged via the antenna coil, a protocol change field programmable gate array (FPGA) unit adapted and configured to selectably process data modulated or demodulated by the RF transmitting/receiving unit, and a memory unit adapted and configured to store data processed by the protocol change FPGA unit. Preferably, the protocol FPGA unit includes a plurality of differently programmed RF transport protocol circuits selected based on code data stored in the memory unit.
