Cell Phone, Laptop & Tablet Testing

Cell Phones

All cell phone models must be tested to meet the SAR requirements for  most all countries around the world. All bands and technologies are  tested or evaluated against the requirements. The phone is tested using a  phantom head on both the right and left side of the head in a touch  configuration. The phone is also tested with the phone touching the ear  and tilted away from the cheek 15º. The phone is then moved to a flat  phantom to simulate the phone next to the body. It is tested with a  specified separation distance, which is included in the user’s guide.  The US requirements are listed in OET bulletin 65 Supplement C, KDB  447498, KDB 648474 and KDB 941225. The testing procedure for a handset  is described in IEEE1528-2005. The EU requirements are listed in IEC  62209 Parts 1 and 2.

Laptops & Tablets

If the antenna is located within 20 cm (8.5 inches) of the body, the laptop would require SAR testing for radio frequency exposure limits.  For laptops with antenna located at the top of a large LCD, SAR testing  may not be required. The SAR testing includes all transmitters  installed in the laptop or tablet computer. If the WLAN is a diversity  antenna design, all antennas must be tested and evaluated for the SAR requirements.  The laptops are tested with the bottom of the laptop in contact with  the flat phantom only. All tablets are tested for RF exposure limits on  the bottom of the tablet as well as the side at the bottom of the LCD  screen in both landscape and portrait modes if applicable. The US SAR  requirements are listed in OET bulletin 65 Supplement C, KDB 447498, KDB  248227, KDB 616216 and KDB 941225. The EU requirements are listed in  IEC 62209 Part 2.
