Are the WLAN cards safe to use from a health perspective since they use microwave frequencies?
A. The WLAN devices are safe when used under normal operating conditions as stated in the user manuals. The power levels are below the power level of a typical microwave oven. The radio modules were tested by independent test labs in accordance with various recognized standards. The levels measured when the PCMCIA antenna was 1 cm away from the user were recorded at 10-12% of the maximum level allowed. Q. The FCC limits the maximum system power to 4 watts Effective Isotropically Radiated Power (EIRP) for non point-to-point systems. However, a properly tested and certified system is allowed to exceed the 4 watt EIRP for a point-to-point system. I have two parabolic dishes aimed at an Omni. Can I exceed the 4 watt EIRP limit if I consider each leg point-to-point? A. No. The FCC defines the system that uses directional gain antennas as only part of the complete system. You cannot exceed the 4W EIRP for any of the legs of this system since the whole system is a point-to-multipoint. This to
