Hi there

If one familiar with RFID systems knows one of the operation frequencies of this systems is 6.8 GHz, however I could not find the bandwidth of RFID at 6.8 GHz. Is this from 6.65~6.95 GHz or not.....???

Can anybody help?

Thx buddy....
But how come I could NOT find it in anywhere?
Would you please introduce me a reference for this? Book, paper, etc.

Really appreciate in advance.
Good luck
 

I don't recognize 6.8 GHz as a commonly accepted RFID frequency, it's neither mentioned in FCC or ETSI documents. Where do you see it specified?

I think the authors meant 5.8GHz (ISM band).
If you look at frequency regulations, 6.8GHz is a satellite communication band.

Thx, I'll check this out.
But there are other references that tried to reject this band (i.e. 6.8 GHz RFID).

Thx again.

My best guess is that someone started with a typo (6.8GHz instead of 5.8GHZ) and others based their designs on that mistake. If you search for "6.8GHz RFID" your edaboard thread is now at position #1, indicating that there are very few publications for that keyword.
