The radio spectrum in each country is controlled by regulators within that country. RFID is, however, an enabling asset and the regulations impact its own citizens and the competitiveness of its own industries. The laws of physics dictate that UHF is a very important frequency for RFID range performance with minimum power levels. But this band has not been available in many countries.
Trolley Scan has reported on the following developments in frequency allocations that are now happening:
* Japan is allocating a frequency near 956 MHz for RFID. Trolley Scan is only the second supplier to have equipment that meets these requirements and this will be supplied to users in Japan. Japan has resisted a UHF allocation for the past 20 years.
* The UK has decided to establish a second RFID frequency at higher power levels than that currently available to EU countries. Obviously the UK has decided that the low powers currently allowed to EU citizens are holding back developments in the UK.
* Korea, Singapore and Israel are in the process of establishing UHF RFID frequencies at sensible power levels for passive RFID.
Eventually every country in the world will hopefully have an allocation within its spectrum plan in the band 860 to 956 MHz for passive RFID. Due to the wide band characteristics of the transponders (frequency agility), transponders that are attached to goods should be readable by readers in every country.
For new users who wish to evaluate UHF RFID and their applications without needing specialised skills, Trolley Scan provides small systems that comprise a reader, antennas and 100 transponders. See www.trolleyscan.com/isosys.html
