Notes:

    (1) Occupational/controlled exposure 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 a person is transient
        through a location where occupational/controlled limits apply provided he or she is made
        aware of the potential for exposure.

    (2) General population/uncontrolled exposure limits apply in situations in which the general
        public may be exposed, or in which persons who are exposed as a consequence of their
        employment may not be fully aware of the potential for exposure or cannot exercise
        control over their exposure

   5.3.          EQUATIONS
POWER DENSITY

Power density is given by:

S = EIRP / (4 * Pi * D^2)

Where

S = Power density in mW/cm^2
EIRP = Equivalent Isotropic Radiated Power in mW
D = Separation distance in cm

Power density in units of mW/cm^2 is converted to units of W/m^2 by multiplying by 10.


DISTANCE

Distance is given by:

D = SQRT (EIRP / (4 * Pi * S))

Where

D = Separation distance in cm
EIRP = Equivalent Isotropic Radiated Power in mW
S = Power density in mW/cm^2


SOURCE-BASED DUTY CYCLE

Where applicable (for example, multi-slot cell phone applications) a duty cycle factor may be
applied.

Source-based time-averaged EIRP = (DC / 100) * EIRP

Where

DC = Duty Cycle in %, as applicable
EIRP = Equivalent Isotropic Radiated Power in W

MIMO AND COLOCATED TRANSMITTERS (IDENTICAL LIMIT FOR ALL TRANSMITTERS)

For multiple chain devices, and colocated transmitters operating simultaneously in frequency
bands where the limit is identical, the total power density is calculated using the total EIRP
obtained by summing the EIRP (in linear units) of each transmitter.

Total EIRP = (EIRP1) + (EIRP2) + ... + (EIRPn)

where

EIRPx = Source-based time-averaged EIRP of chain x or transmitter x

The total EIRP is then used to calculate the Power Density or the Distance as applicable.


MIMO AND COLOCATED TRANSMITTERS

For multiple colocated transmitters operating simultaneously in frequency bands where different
limits apply:

The Power Density at the specified separation distance is calculated for each transmitter chain
or transmitter.

The fraction of the exposure limit is calculated for each chain or transmitter as
(Power Density of chain or transmitter) / (Limit applicable to that chain or transmitter).

The fractions are summed.

Compliance is established if the sum of the fractions is less than or equal to one.

    5.4.          LIMITS AND IC EXEMPTION
VARIABLE LIMITS

For mobile radio equipment operating in the cellular phone band, the lowest power density limit
is calculated using the lowest frequency:

824 MHz / 1500 = 0.55 mW/cm^2 (FCC)
S = 0.02619 ƒ 0.6834 W/m^2 (IC).


FIXED LIMITS

For operation in the PCS band, the 2.4 GHz band and the 5 GHz bands:

From FCC §1.1310 Table 1 (B), the maximum value of S = 1.0 mW/cm^2
From IC Safety Code 6, Section 4 Table 4 Column 4, S = 0.02619 ƒ 0.6834 W/m^2


INDUSTRY CANADA EXEMPTION

RF exposure evaluation is required if the separation distance between the user and/or
bystander and the device’s radiating element is greater than 20 cm, except when the device
operates as follows:

•        below 20 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is
         equal to or less than 1 W (adjusted for tune-up tolerance);
•        at or above 20 MHz and below 48 MHz and the source-based, time-averaged maximum
         e.i.r.p. of the device is equal to or less than 4.49/ƒ0.5 W (adjusted for tune-up tolerance),
         where ƒ is in MHz;
•        at or above 48 MHz and below 300 MHz and the source-based, time-averaged
         maximum e.i.r.p. of the device is equal to or less than 0.6 W (adjusted for tune-up
         tolerance);
•        at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum
         e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ0.6834 W (adjusted for tune-up
         tolerance), where ƒ is in MHz;
•        at or above 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device
         is equal to or less than 5 W (adjusted for tune-up tolerance).

In these cases, the information contained in the RF exposure technical brief may be limited to
information that demonstrates how the e.i.r.p. was derived.

Notes:

   1) The manufacturer configures output power so that the maximum power, after accounting
      for manufacturing tolerances, will never exceed the maximum power level measured.
   2) The output power in the tables above is the maximum power per chain among various
      channels and various modes within the specific band.
