RF EXPOSURE REQUIRMENTS [§§ 15.247(i), 1.1310 & 2.1091] 5.7.1. Limits § 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b). Limits for Maximum Permissible Exposure (MPE) Frequency range Electric field strength Magnetic field strength Power density Averaging time (MHz) (V/m) (A/m) (mW/cm2) (minutes) (A) Limits for Occupational/Controlled Exposures 0.3-3.0 614 1.63 *(100) 6 2 3.0-30 1842/f 4.89/f *(900/f ) 6 30-300 61.4 0.163 1.0 6 300-1500 f/300 6 1500-100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 2 1.34-30 824/f 2.19/f *(180/f ) 30 30-300 27.5 0.073 0.2 30 300-1500 f/1500 30 1500-100,000 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density Note 1: Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure. Note 2: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure.

Co-location Pursuant to KDB 447498 D01 General RF Exposure Guidance v06, Section 7.2: Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneously transmitting antennas incorporated in a host device is ≤ 1.0, according to calculated/estimated, numerically modeled, or measured field strengths or power density. Co-location will only applies to EUT with 2 dBi dipole antenna, worst case EIRP of 32 dBm will be used in co- location at the minimum 23 cm evaluation separation distance required by the operating configurations and exposure conditions of the host device.
