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.          IC EXEMPTION

INDUSTRY CANADA EXEMPTION

RSS-102 Clause 2.5.2 RF exposure evaluation is required if the separation distance between
the user and the device’s radiating element is greater than 20 cm, except when the device
operates as follows:


• 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;

6. RF EXPOSURE RESULTS
In the table(s) below, Power and Gain are entered in units of dBm and dBi respectively and
conversions to linear forms are used for the calculations.

* Certified WiFi module

The device operates above 300 MHz and below 6 GHz with a maximum EIRP less than or
equal to 2.7 Watts in 2.4GHz band as a mobile device with a minimum separation distance of 20
cm, therefore it is exempt from routine RF Exposure Evaluation under RSS-102.

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.

   3) The antenna gain in the tables above is the maximum antenna gain among various
      channels within the specified band.

   4) A tolerance value of +0.7 dB was included in the output power values above for 2.4GHz
      802.15.4 mode to cover the output power tolerance under extreme conditions in the real
      filed as declared by the client. For Wifi mode the data was obtained from the certified
      module MPE report.
