Modem Testing


USB modems are tested for SAR on all 5 sides of the modem with a 5 mm  gap between the modem face and the flat phantom. If there are multiple  antennas and technologies in the modem, all antennas and technologies  must be tested to meet the SAR requirement. All PCMCIA/express cards are  tested on the bottom surface with a gap of 10 mm from the phantom for  the US SAR requirements. The only exception is if the  PCMCIA/express card is installed into a PDA; then, the device must be SAR tested with a 5 mm gap from the phantom. The EU requires that all  sides of the device be tested at a distance not to exceed 25 mm. The US  SAR and RF exposure limit requirements are listed in OET bulletin 65  Supplement C, KDB 447498, KDB 248227 and KDB 941225. The EU requirements  are listed in IEC 62209 Part 2.
