PAGE 129 OF 140
There are different UHF operating frequency standards all over the world, regulated
by governmental authorities in most countries: for instance, Federal Communications
Commission (FCC) in the United States and ETSI (European Telecommunications
Standards Institute) in Europe.
Globally, each country has its own frequency allocation for RFID.
For instance, RFID UHF bands are:
865–870 MHz in Europe
902–928 MHz in North and South America
950–956 MHz in Japan and some Asian countries
