4.6. Regulatory agencies in EU countries and the USA
The design and RF power of the antennas is affected mainly by the country-specific RF regula-
tions. The entire EU geographic area is covered under uniform limits specified in the R&TTE
guideline and EN 300 330. In North America this is regulated by FCC Part 15.
In EU countries the maximum permissible field strength at 13.56 MHz at a distance of 10 m is:
42dB
µ
A/m. In the USA this is 38dB
µ
A/m.
When commissioning the system, be sure that the permissible values as prescribed by the national
regulatory agency are not exceeded.
Since FCC Part 15 prescribes a separation of 50 dB between the carrier and sidebands, the
Reader may be operated in the USA only using 1 of 256 bit coding (modulation).
When using Reader ID ISC.LR200-B and under optimum ambient conditions, the antennas can be
operated in the configuration as described here in EU countries using a maximum of 4 W, or 1.5 W
in the USA. If the limit values are higher or lower, the RF power must be adjusted accordingly or
the magnetic radiation needs to be reduced by shielding the antennas.
When commissioning the antennas, the system integrator should be sure that the installation in-
structions are followed, the necessary Reader settings have been made and that the limit values
prescribed by the national regulatory agency are not exceeded.
Furthermore the Reader must be configured as follows:
