(Sorry if this posts twice)
Hello All,
I am trying to capture the communications between a RFID reader and
an EPC Gen 2 tag (920 MHz). I tapped directly into the antenna of a
Thinkmagic M5e RFID reader. I turn it on and it starts reading the
tags. When I look at the raw signal from the usrp or an Agilent
signal analyzer, I can clearly make out the reader-to-tag data bursts.
But, I don't see the tag-to-reader bursts. I know they should be
considerably smaller in amplitude, but all I see is noise.
Has anyone had any luck capturing this type of data? Any suggestions
would be greatly appreciated.
Thanks in advance,
Kevin
